10-piece carbide router bit set

This set contains ten single-flute up-spiral cutters made from tungsten cobalt alloy. Each bit measures 3.175 mm shank diameter, 17 mm cutting length and 38 mm overall length. They are designed for CNC routing of acrylic, PVC, plastic, wood, multilayer board, plywood and MDF where a high surface finish is required.

Optimised for high-speed spindle work

Recommended spindle speed is 20000 to 24000 RPM with a feed rate of 1 to 10 metres per minute depending on the material being cut. The up-spiral geometry clears chips upward, reducing heat build-up in the workpiece. Users must match feed and speed to the specific substrate to avoid tool wear or material melting.

Questions about this item

How long can the 3.175 mm carbide flute run continuously at 24000 RPM before it dulls?

Tool life depends on the material being cut and the feed rate used. At the recommended 1-10 m/min feed range the cutter maintains its edge through extended production runs on acrylic, PVC, MDF and similar substrates.

How hot does the shank get during a full day of CNC routing at 20000 RPM?

The tungsten-cobalt alloy dissipates heat efficiently, so the shank stays warm rather than hot even during continuous operation at the rated spindle speeds. Proper chip evacuation at the suggested feed rates keeps temperatures stable.
