1.. Equipment used in producing is totally designed by ourselves to produce high quality products.
2. The body materials can join both hardness and strength together perfectly after the third time heat treatment.
3. We have advanced testing equipment to test all the key processing parts to avoid low quality products.
Size:
| Diameter | Thickness | Bore | Teeth | Length (mm) |
| 210 | 4.0 | 50/70 | 4 | 12 |
| 250 | 3.8 | 50/70 | 6 | 12 |
| 250 | 4.0 | 50/70 | 6 | 12 |
Applications
Finger Jointing: Creates strong, durable joints for furniture, cabinetry, and woodworking projects.
Design and Construction
The CXA-series finger joint cutterhead spans 210 and 250 mm diameters: 210 x 70 x 4.0 with 4 teeth, and 250 x 3.8/4.0 with 6 teeth, bores 50/70 mm, finger length 12 mm — the large-format programme for heavy finger-jointing lines, per the specifications table.
How It Works
The larger diameters give the teeth a longer cutting arc and better heat spread at line speeds on thick stock. Four- and six-tooth programmes match the feed rate of the jointing line; the 12 mm finger length covers the standard structural joint.
Applications
- Heavy finger-jointing lines
- Large-format jointing cutterheads
- Structural timber jointing
- Glulam production
Suitable Materials
- Solid wood
- Hardwood and softwood stock
- Engineered wood
- Glulam components
Large-format carbide plates hold the finger profile at heavy-line feed rates.
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
Cutter set. Order by the diameter, thickness, bore, tooth count and finger length stated in the specifications table below.
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.
