10-Piece Carbide Router Bit Set

This 10-piece set of single-flute up-spiral cutters is designed for CNC routing in acrylic, PVC, plastic, wood, multilayer board, plywood and MDF. Each bit features a 3.175 mm shank with a 17 mm cutting length and 38 mm overall length, made from tungsten cobalt alloy for high surface finish results. The pack suits hobbyists and small workshops running multi-material jobs.

Recommended Speeds and Heat Management

Run the bits between 20,000 and 24,000 RPM with a feed rate of 1 to 10 metres per minute, adjusting for the specific material. The single-flute geometry evacuates chips efficiently, reducing heat build-up in plastics and soft woods. Proper speed selection prevents melting or burning, keeping power draw steady on compatible CNC spindles.

Questions about this item

How do I fit the 3.175 mm shank into my CNC collet without damaging the cutter?

Insert the 3.175 mm shank fully into a matching collet, tighten the nut to the machine maker's torque, and confirm the 17 mm flute length clears the workpiece before starting the spindle.

When should I replace these carbide router bits?

Replace the cutters when the single flute shows visible wear, chipping, or when cut quality on acrylic, PVC or MDF deteriorates despite running at 20000-24000 RPM with a 1-10 m/min feed rate.
