Features
*Made from premium-grade carbide for exceptional durability, resistance to wear, and extended tool life.
*Features a 35° cutting angle, designed to deliver clean, smooth, and accurate cuts, minimizing tear-out in both hardwoods and softwoods.
*Includes 3 precision-drilled holes for secure attachment to cutting heads, allowing for quick indexing. This feature enables easy rotation or flipping of the knife to use a fresh edge, enhancing efficiency and reducing downtime.
Appications
The 50x12x1.7-35° 3 Holes Indexable Carbide Knives are versatile tools widely used in woodworking applications. They excel in wood planing, ensuring smooth and even surfaces, and in jointing, where they straighten and flatten edges for seamless joints. Their precision allows for detailed wood profiling, creating intricate edges and designs. These knives are effective in cutting composite materials like MDF and plywood, providing clean results without splintering. Additionally, they offer precision in laminate trimming, end-grain cutting, and are essential in custom furniture and cabinet making for accurate sizing and shaping. Their reliability also makes them popular among DIY enthusiasts for various woodworking projects. Overall, these carbide knives deliver exceptional performance, durability, and precision across a wide range of woodworking tasks.
Design and Construction
The 50 x 12 x 1.7 mm indexable carbide knife (35° bevel, 3 holes) is a replaceable tungsten carbide insert for planing and jointing cutterheads. Length 50 mm, width 12 mm, thickness 1.7 mm, four cutting edges (Z4) at a 35° bevel, mounted through three screw holes.
How It Works
The three screw holes hold the long insert flat across its full width, so the four edges present a straight, stable cutting line over the 50 mm length. When an edge dulls, the knife is indexed or replaced in minutes and the cutterhead stays balanced in the machine.
Applications
- Planing and jointing cutterheads
- Wide-block helical cutterheads
- Spindle moulders
- High-volume planing lines
Suitable Materials
- Solid wood
- MDF and particleboard
- Plywood and veneered panels
- Laminated boards
Four edges per knife and a stable three-screw mount keep the cutting line straight across long planing runs.
System Comparison: Replaceable Insert vs. Solid Knife
Insert knives keep the cutterhead in service and replace only the cutting edge. For production cutterheads running repeat profiles, 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 knife (box quantities on request). Order by the length, width, thickness and bevel 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, bores, cutting widths and tooth counts built to your drawing or sample.
- Non-standard fabrication — profiles and sizes outside the standard catalogue, including profile restoration.
- 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; 40Cr chrome-molybdenum steel bodies; 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 insert knife is inspected before shipment. Length, width, thickness, bevel angle and edge geometry are measured against the values stated for each part number, and edge lines are checked straight and free of chips under magnification.
Inserts measuring outside tolerance do not ship. Inspection is performed under our ISO 9001 quality system, with batch records retained for traceability.

Frequently Asked Questions
What speed and feed should I start with?
＋See the performance data table above — start mid-range and tune by chip load, finish and heat.
How do I know the parameters need adjusting?
＋Fuzzing means too much feed for the speed; burning means too little. Change one variable at a time.
Do you supply custom sizes?
＋Yes — send a drawing or sample; custom diameters, shanks and geometries are produced to order.
