Arbortech TURBOplane

Identity

Name: TURBOplane (also styled TURBOPlane, TURBO Plane) — an Arbortech product, SKU IND.FG.400.20 (SKU per Arbortech's US page, as relayed by the review). Not to be confused with King Arthur's Tools' "Holey Galahad," a different product from a different manufacturer. They are alike in market position (both are angle-grinder wood-shaping discs) and differ in construction.

Family/category: A rotary planing/shaping disc for an angle grinder, with multiple internally positioned tungsten-carbide cutting edges or teeth and no cutting teeth on the outer periphery. Arbortech's page says "No teeth on the periphery of the disc, making it ideal for template work" and describes a "Tungsten carbide cutting edge that can be resharpened." the review reports the same page using "carbide teeth," and US design patents D672795 and D678370 are titled "Turbo plane blade with four teeth" and "Turbo plane blade with three teeth." So it is not toothless and not one continuous edge: the accurate claim is no teeth on the periphery, not "no teeth." It is not an abrader (no fixed grit). Its observed action is intermittent cutting by discrete internal carbide cutters. Whether Hewn's SEVER-versus-ABRADE boundary is drawn broadly enough to include intermittent rotary cutter teeth is a family-boundary call for Haft or Jonathan; this entry places it on the severing side provisionally and does not force a lineage.

One-line: A rotary carbide-cutter disc for an angle grinder with a non-cutting outer rim. Its action overlaps functionally with some hand-plane and spokeshave work, but it does not reproduce their reference surfaces, precision, feedback or risk profile. Manufacturer-marketed as controllable and suitable for all skill levels (a marketing claim, not a safety rating).

✦ How NOT to use it

Pre-use gate (all items must be satisfied before the disc turns). From the support page and Getting Started article read this pass, plus the reviewer's account of the manual [manual, relayed] where marked:

• Confirm the exact TURBOplane model, spindle (5/8" NA or M14), grinder size, rated speed (disc maximum 12,000 RPM; grinder at least 9,000 RPM) and minimum 550 W power.
• Use the grinder's original metal guard, positioned as the current manual instructs. Arbortech's support page asks for a guard that rotates and locks at 45 degrees; the reviewer reports the manual requires guard orientation of about 45 degrees [manual, relayed]. Arbortech's Getting Started article says guards should always be used with blades.
• Fit the auxiliary handle.
• Mount with the correct flange, spacer and locknut stack, with full locknut engagement, and the correct cutter direction [manual, relayed]. Specific directions and sequence are not reproduced here; take them from the manual for the exact SKU.
• Inspect the disc for damage and wear before use, and compare against the manufacturer's wear limit. The reviewer reports the manual gives a blade-thickness discard threshold after sharpening [manual, relayed]. The figure is not given here and must come from the exact manual revision used.
• Disconnect power before mounting, inspection, cleaning or sharpening (support page, for sharpening; [manual, relayed] for mounting and inspection).

During use. Two hands, always ("Always use two hands when operating a power tool"). Secure the work: Arbortech says "a G clamp is all you need to hold your wood steady," at a work height that is neither too high nor too low. Light touch ("Use a light touch with a rotary tool, let the high speed do all the work"), with controlled passes. Stop immediately and disconnect if there is vibration, jumpiness, damage or imbalance. The support page says jumpiness or imbalance most likely means incorrect fitting; refit per the instructions, and if it persists, test on another good-quality angle grinder (that second step is a test of the grinder, not a licence to keep running a damaged disc).

PPE and area. Arbortech's Getting Started article: "Make sure you have the appropriate Respiratory, Eye and Ear Protection." Treat eye or face, hearing and respiratory protection as required, not optional. The article does not address clothing; the review calls for suitable close-fitting clothing and PPE. Control debris and keep bystanders clear (the reviewer; sources of the debris and bystander wording not read).

Hazards the absence of peripheral teeth does not remove. Contact injury, kickback, mounting and overspeed failure, ejection of debris or fragments, dust, noise, and loss of workpiece control. The original's statement that "standard angle-grinder precautions still apply" is replaced by the gate above.

dangerous. Not low-risk by default. Hazards are those listed above, and any injury is a high-speed carbide cutter injury. The original entry searched forums, UK OPSS and product-liability sources and located no injury account naming TURBOplane. That is a bounded research result, not a risk assessment: it does not show that no incident, alert or injury record exists, and it must not be read as evidence of low hazard. The original did not record the databases, exact search terms or search date beyond "UK OPSS, named forums, product-liability/legal-marketing sources, July 2026." Incident history is unknown.

Coating gate. Old paint can contain lead or other hazardous substances, and high-speed removal makes the dust easily inhalable and spreads it through the work area. Arbortech lists paint stripping as an incidental use; that is marketing and it does not address coating hazards. Use the TURBOplane on a coating only after the coating has been identified as safe for mechanical removal, and an appropriate dust-control, respiratory-protection, containment and cleanup plan is in place. Do not power-strip suspected lead or other hazardous coatings without applicable specialist controls. The review is the source of this gate; the underlying authorities (for example lead-paint guidance) were not fetched in this pass.

damaging. Misuse that damages the disc includes the conditions named above: incorrect fitting, wear past the manufacturer's limit and sharpening beyond the manual. The support page warns against sharpening too early and gives the direction of the diamond-file stroke. The original found no other damage-mechanics source.

beginner-trap. The expectation trap in the original stands as the original run's reading: a beginner drawn to this corner of the corpus by the Lancelot's reputation may expect TURBOplane to hollow or bulk-remove the same way. Separately, a beginner reading "ideal for all skill levels" may take it as clearance; it is not (see access).

lineage-misuse — mechanism confusion. The original's strongest finding stands in corrected form. Forum posters (LumberJocks 2015, Sawmill Creek 2012, as read by the original run; not re-read this pass) discuss TURBOplane and Holey Galahad as though choosing between variants of the same tool. They are different products from different manufacturers with different cutting constructions: TURBOplane has multiple internal carbide cutters on a disc with a non-cutting rim and can be resharpened; Holey Galahad has structured tungsten-carbide teeth bonded to a steel disc and is cleaned and reused. The original's "one shears, the other grinds" shorthand is dropped as unverified. Choose between them on cutting geometry, access, removal rate, surface result, guarding and mounting requirements and project shape, not on appearance or a generic "safer carving disc" label.

Correct use

What it's genuinely good at. Arbortech's page lists planing, freehand shaping and template work; flat use for leveling and planing; angled use for shallow shaping, sculpting, and convex and concave forms. Manufacturer-named applications in the original include bowl exteriors, chair seats and log-furniture surfaces. Because the periphery has no cutting teeth, the disc is designed for template-guided work (manufacturer claim). Suitable for flat, convex, and accessible shallow-concave shaping. Removal rate is a function of presentation and pressure, so stage of work is chosen by geometry, access, removal rate and the surface wanted, not by a fixed rough-mid-finish order.

What it handles poorly. Not the preferred tool for deep, narrow, rim-led or blind recesses, where the face cutters cannot keep safe contact and clearance, and where the lack of peripheral cutting teeth removes the rim-led plunge approach. The original's categorical "not for interior hollowing" is narrowed accordingly: Arbortech markets concave shaping and a simple-bowl project (per the review; project page not read). Finish quality ("minimal sanding") is a manufacturer claim not independently tested. Not for precision joinery or reference-surface work.

Relation to hand tools. It performs powered freehand planing and shaping tasks that may overlap with some spokeshave or hand-plane work, but it does not reproduce their reference surfaces, precision, feedback, or risk profile (feed direction, depth control, cutter marks, noise, and chip and dust projection all differ).

✦ Matching — for the app's read

does: freehand rotary planing, leveling, rapid shaping, sculpting and surface stock removal.

suits: broad flat surfaces, convex forms, accessible shallow concavities, freeform shaping, and template-guided profiles when the exact setup permits. Examples from the original: bowl and dough-bowl exteriors, chair seats, log and rustic furniture surfaces. Paint stripping is not matched (see not-for and the coating gate).

stage: variable. It can remove stock rapidly or make shallower passes depending on presentation and pressure. Not hard-coded after a separate roughing tool.

kit-fit: conditional on the exact regional spindle, the grinder's size, original metal guard, auxiliary handle, available locknut engagement, power and rated speed, and not simply ownership of any 4 to 5 inch angle grinder. Support-page requirements (read): a metal guard that can be rotated and fixed to 45 degrees; a grinder with an auxiliary handle; the on/off switch on the top or side; at least 550 W; and a grinder that runs at 9,000 RPM or higher. Grinder diameter: Arbortech's US page lists 115 mm (4 1/2") and 125 mm (5") in its specification and 4" (100 mm) or 4 1/2" (115 mm) in its features text, which disagree. The reviewer reports an older manual naming 100 and 115 mm and current support material naming 115 and 125 mm [manual, relayed]. Verify against the manual and support page for the exact SKU and grinder, and do not rely on a universal 4/4.5/5-inch claim. Arbortech's Contour Sander and Diamond File are named companions in the original entry (not re-checked).

not-for:

• deep, narrow, blind or rim-led recesses;
• uncontrolled plunge cuts;
• precision joinery and reference-surface work;
• grinders that do not meet the compatibility conditions above;
• use without the grinder's original metal guard and auxiliary handle;
• paint, varnish or coating removal unless the coating gate below is passed. Do not power-strip suspected lead or other hazardous coatings without applicable specialist controls;
• anything requiring a certified safe-by-injury-rate claim.

access: Arbortech markets the disc as "ideal for all skill levels." That is manufacturer marketing, not an independent safety rating, injury-rate evidence or a certification. The no-periphery-teeth design is a control feature for template work and does not remove angle-grinder hazards. Experienced supervision or training, and compliance with the manual, matter more than the maker's skill-level line. Do not give beginner clearance on the strength of it.

revival: none found in the original pass; not further researched.

Anatomy

• Disc body — a steel disc with no cutting teeth on the periphery. This non-cutting rim is the manufacturer's stated basis for template-guided work.
• Cutting edges — multiple tungsten-carbide teeth or cutting edges set internally in the disc (Arbortech copy as cited by the reviewer: "durable carbide teeth," "wide cutting edges"; patents show three-tooth and four-tooth designs). Cutter count for the current product is not asserted here.
• Resharpenable — the maker says the carbide cutting edge can be resharpened. Arbortech's support page (read) says: disconnect the power first, use a small flat diamond file such as the Arbortech Diamond File, and "work ACROSS the face of the tooth." It warns against sharpening too early. No angle or interval is given here because none is stated in what was read. This is a different maintenance model from Holey Galahad (bonded structured teeth, cleaned and reused) and should not be called equivalent. The Lancelot is described in its own entry.
• Arbor/mounting bore — Arbortech's US page: "Suits 5/8” only" (North America) and "Suits M14 only" (EU and Australia). Hardware shipped with it (the original says two spacer washers) is not verified; see the pre-use gate for the flange, spacer and locknut stack.
• Rated speed — "Max. 12,000" RPM per the US page.
• Grinder size — see Variations and the pre-use gate. The page is inconsistent and this entry does not give a universal size.
• No chain, no bar, no chain brake — carried from the original sibling-entry framing. These absences do not remove angle-grinder hazards.

Variations (living)

Prices are as listed on the sources named, read 2026-10-16, list or sale as shown, USD, US seller pages. They move; re-check before relying on them.

Within the TURBOplane line, the original found a single cutting geometry. The review and the patent record show Mini TURBO variants exist, so this is no longer asserted. Clone presence was not verified.

Trades

Power woodcarving (primary); woodturning (bowl and vessel exterior shaping); log and rustic furniture making; general power-sculpting. The original found no arboriculture-adjacent use for TURBOplane in its pass; not searched further.

Lineage

Ancestors: Unknown as a documented line. Functionally the hand plane and spokeshave do overlapping shaping work; that is an analogy, not a descent. The host platform is the angle grinder. Arbortech's own earlier Arbortech Carving Disc is a sibling product from the same maker (company dated ~1988 in that entry, carried here, not re-checked); whether one influenced the other is unknown.

Descendants: Unknown. The patent record shows later design patents citing D672795 (USD719593S1 "Mini turbo plane blade with three teeth" and USD719592S1 "Mini turbo plane blade with two teeth"), so at least a Mini TURBO line followed the original design. No broader descendant search was made.

Contemporaries / cousins:

• Arbortech Carving Disc — same manufacturer, same power-carving range, a different cutter arrangement (discrete teeth, rim cutting per that entry). Arbortech's own marketing runs a "TurboPlane V Burr disc" comparison (as stated in the original entry; not re-read this pass).
• King Arthur's Tools "Holey Galahad" — a different manufacturer's disc. KAT's product-information page (read this pass) describes "high quality structured tungsten carbide teeth, meticulously bonded to steel discs," says "Discs can be cleaned and reused multiple times," and rates them at a maximum 14,000 RPM. Its category page shows a 6-hole "see through" design, Round and Flat profiles, and four coarseness grades. It is closer to the Structured-Tooth Carving Burr than to TURBOplane's discrete resharpenable cutters. Do not treat the two as equivalent.
• Lancelot (King Arthur's Tools) — a chain-loop disc, built earlier in the corpus. The two sit in a similar buying context with very different cutting mechanisms; matching should use mechanism, access, removal rate and surface result, not market position.
• Structured-Tooth Carving Burr — bonded carbide tooth tool, a third mechanism.
• Arbortech's Contour Sander — the maker's named follow-up accessory (per the original entry; not re-read this pass).

History

Origin. The manufacturer is Arbortech, an Australian power-carving tool company (the corpus's Arbortech Carving Disc entry dates it ~1988; carried, not re-checked). Arbortech's US product page lists the TURBOplane at $179.00 USD (US page, read 2026-10-16; its RRP is also shown as $179.00). The original entry's "$149" is withdrawn: The review suggests it may be the price of the Mini TURBO Kit or a past discount, and I have not checked that. The TURBOplane launch year is unknown. The patent dates below establish documented designs, not a first sale date.

Patents. Relevant records exist; the original entry's negative result was wrong.

• US D672795 S1, "Turbo plane blade with four teeth." Inventor Kevin Ross Inkster. Application US 29/421,008, filed May 4, 2012, published December 18, 2012. Google Patents lists a priority date of November 10, 2011 in its family table and shows legal status "Active" with an anticipated expiry of December 18, 2026, which Google flags as an assumption and not a legal conclusion. This is an ornamental design patent. (Read directly this pass.)
• US D678370 S1, "Turbo plane blade with three teeth," published March 19, 2013, a continuation-in-part of the above, per the D672795 record. Not fetched itself.
• US 2013/0118642 A1, "Rotary planing tool," filed November 8, 2012, sharing the 2011 priority date. This is a utility patent application publication; whether it was granted was not checked. The mechanical claims of the utility document were not read.
• Later design patents USD719593S1 (three teeth, "Mini") and USD719592S1 (two teeth, "Mini") cite D672795, per its record.

Cutter count matters: the marketed product's current photographs and spec copy should be matched to the exact revision (three-tooth or four-tooth designs exist) before this entry asserts a number of cutters. This entry does not.

Relationship to Holey Galahad and King Arthur's Tools. The original run began by conflating the two products and corrected itself; that correction stands. The original entry's account of King Arthur's Tools (founded 1990 by Arthur Aveling, per a 2006 Journal of Light Construction profile) is carried from the original and was not re-read this pass. Any influence or licensing between Arbortech and King Arthur's Tools is unknown. The original phrase "parallel, independent invention" is withdrawn: absence of a cross-reference in company histories does not show independence.

Form-follows-failure reading. The original entry read Arbortech's range as a stage-of-work fork between its toothed Carving Disc and the TURBOplane. That is the original run's reading of marketing material; the review says the source does not establish that TURBOplane must follow another roughing tool. Treat it as an interpretation, not a documented design history.

Human side

Traditions & trades. Power woodcarving, bowl exterior shaping, log and rustic furniture, general power-sculpting, the same broad community as the corpus's other power-carving-disc entries. The original's skew toward makers who pay a premium for a "single resharpenable capital tool rather than a wear-and-replace grit disc" is withdrawn: Holey Galahad discs are reusable and cleanable (KAT), and are not cheap consumables.

Cultures & regions. No distinct regional tradition identified in the original pass. Retailers named there (Highland Woodworking, Axminster, sautershop, woodcarvingtools.org) were not re-checked; treat the retailer list as unverified.

Named hands / real accounts. These are the original run's forum readings, carried and not re-read this pass; they are user reports, not evidence of mechanism, safety, price or lineage.

• "Nic" (LumberJocks, 2015) — a self-reported new Lancelot buyer weighing TURBOplane against Holey Galahad, who wrote of toothed and chain discs generally: "these things are some of the more questionably safe tools I've seen... I read enough horror stories." Aimed at the toothed/chain family, not specifically at TURBOplane.
• Ryan Baker (Sawmill Creek, 2012, a Holey Galahad thread that also names TURBOplane) — described the toothed-disc family as "fast cutting, yet pretty easy to control," with caution about hand placement near the wheel. His injury caution concerns the Galahad, not TURBOplane.
• KAT and Arbortech site testimonials are marketing-page quotes, not independently verified makers, and are not used as evidence.

Stories. The original run found a comparison pattern: forum posters discussing TURBOplane and Holey Galahad side by side, weighing price against control and finish. One poster's price line ("you can almost get a round and a flat Holey Galahad for the price of one turbo plane") is dated by what Holey Galahad cost then; current KAT prices are $76.99 to $92.99, so it should not be read as a price comparison today. No single named-maker account specific to TURBOplane was located in that pass. ArboristSite and Arbtalk were not searched.

✦ Proof of existence

Earliest dated/physical example: The earliest dated record located is the design patent US D672795 S1, filed May 4, 2012 and published December 18, 2012, with a family-table priority date of November 10, 2011. This shows a documented design, not a first sale. Launch year: unknown.

Museum/collection records: Not searched in the original pass. No result is claimed either way.

Patents: D672795 (four teeth), D678370 (three teeth), US 2013/0118642 A1 "Rotary planing tool" (utility application publication, grant status not checked), and the later Mini design patents D719593 and D719592. Details under History. Legal status "Active" for D672795 is Google's assumption, not a legal conclusion.

Regulatory/documentary evidence: The original pass located no UK OPSS alert naming TURBOplane or Arbortech. Scope of that search: UK OPSS and the sources named under dangerous, July 2026, exact terms not recorded. No result was located in that bounded pass; that does not establish that none exists. The live manufacturer page (read this pass) and the retailer links in the original are the commercial record.
