3012 Heavy Duty
3012 heavy-duty planing cutterhead, D 62-100 mm, 6T, bore options 40-200 mm. Helical insert design.
The 3012 heavy-duty planing cutterhead carries six teeth (6T) across diameters (D) of 62 to 100+ mm, widths (W) of 35 or 40 mm and bore options (d) from 40 to 200 mm per the size/model matrix in the specifications table — the 3012 programme of the heavy-duty family.
The VPOINT 3012 Heavy Duty is a carbide woodworking cutting tool. Ideal for heavy planing on industrial planers, deep dimensioning cuts and 3012-series head programmes.
Design and Construction
The 3012 heavy-duty planing cutterhead carries six teeth (6T) across diameters (D) of 62 to 100+ mm, widths (W) of 35 or 40 mm and bore options (d) from 40 to 200 mm per the size/model matrix in the specifications table — the 3012 programme of the heavy-duty family.
How It Works
As the head spins, the helical rows of inserts cut a continuous shearing arc: cutting force stays low, noise drops, and the finish shows the characteristic sheared-surface look instead of ripple marks. When an edge dulls, the insert is turned to its second edge or swapped in minutes — the head, its mounting and its balance stay on the spindle.
Applications
- Heavy planing on industrial planers
- Deep dimensioning cuts
- 3012-series head programmes
- High-volume solid wood lines
Suitable Materials
- Solid wood
- MDF and particleboard
- Plywood and veneered panels
- Laminated boards
The heavy-duty helical body holds the insert rows stable through deep cuts.
System Comparison: Replaceable Insert vs. Solid Knife
Insert cutterheads keep the steel body in service and replace only the cutting edges. For production planing and jointing, this is usually the lower-cost way to hold edge quality.
| Property | Replaceable Insert Knife (This Tool) | Solid Profile Knife |
|---|---|---|
| Edge replacement | Swap the worn insert only; the steel body stays in service | Regrind or replace the complete tool |
| Body material | 40Cr chrome-molybdenum steel body, reused across insert changes | Whole tool consumed as the edge wears |
| Downtime per edge change | Minutes — index or swap the insert | Send out for regrinding or buy a new tool |
| Profile changes | Fit a different insert geometry to the same body | New tool required per profile |
| Edge condition | Fresh edge on every change; consistent cut quality | Edge quality drifts between regrinds |
| Best suited for | Production cutterheads with repeat profiles | One-off profiles and low-volume work |
Solid knives remain the better choice for one-off profiles and very low volumes.
Delivery Scope
Single cutterhead. Order by the diameter, width, bore and tooth count stated in the specifications table below (inserts sold separately).
Why Choose VPOINT
- One-year warranty on every cutter — defects in material or workmanship are covered for 12 months from delivery.
- Custom tooling — diameters, shanks, cutting lengths and flute configurations built to your drawing or sample.
- Non-standard fabrication — sizes outside the standard catalogue, including special geometries.
- Resharpening service — cutters return to service after regrinding at a fraction of new-tool cost.
- Factory-direct since 2008 — ISO 9001 manufacturing in Sichuan and Dongguan, China; no trading intermediaries.
Send a drawing, a sample or a worn tool, and our engineering team will quote the exact specification you need.
Precision & Quality Control
Every cutter is inspected before shipment. Shank diameter, cutting-edge diameter, cutting length and overall length are measured against the values listed in the specifications table, and cutting edge runout is verified on the assembled tool.
Tools measuring outside tolerance do not ship. Inspection is performed under our ISO 9001 quality system, with batch records retained for traceability.
