- TypeRight-Angle Drills
- 10-piece set provides multiple cutters for continuous CNC work
- Tungsten steel construction resists wear during abrasive material cuts
- Two-flute design clears chips efficiently for smoother edges
- 4 mm shank fits standard collets without adapters
- Suitable for acrylic, PVC, nylon, resin, wood and plywood
10-Piece Carbide Router Bit Set
This set supplies ten two-flute straight-slot bits made from tungsten steel for CNC machinery. Each cutter measures 4 by 4 by 22 by 45 millimetres and is designed for precise engraving and cutting tasks. The pack suits workshops that need multiple identical bits for continuous production runs.
Industrial Cutting Application Only
The bits are rated for use on acrylic, PVC, nylon, resin, wood and plywood in industrial environments. Safety guidance states the product is not for anyone under 18 years old and must not be used on hazardous materials. Proper machine guarding and personal protective equipment are required during operation.
Sustained CNC Production Workloads
Under continuous CNC routing the solid carbide construction maintains edge geometry across repeated passes in the listed materials. The two-flute design clears chips efficiently during extended cutting sessions without the overheating risk seen in higher-flute alternatives. The ten-piece box allows quick bit rotation to keep throughput steady.

Questions about this item
How do I install the 4 mm shank bits into my CNC collet without damaging the tungsten steel cutting edges?
Use a 4 mm ER collet, tighten the nut to the manufacturer's torque spec while holding the bit by the shank only, and avoid touching the 22 mm flute length during insertion.
When will the 10-piece tungsten steel set need replacement under daily plywood and acrylic routing?
Rotate bits every few hours; expect to resharpen or replace once the 22 mm flute shows visible rounding or chipping on the two-flute edges.
What is the first limitation I will hit when running these 45 mm overall-length bits continuously in dense hardwood?
Heat buildup in the solid carbide body limits sustained feed rates; pause cuts to let the 4 mm shank dissipate heat before the two flutes lose sharpness.
