  • Industrial-grade cutters restricted to users over 18

Five-piece carbide milling cutter set

This five-piece set contains tungsten steel end mills with a 4 mm shank and 22 mm cutting length. Each cutter has two flutes and an up-and-down spiral geometry that compresses the workpiece during routing. A diamond-like carbon coating reduces friction and extends tool life in abrasive wood-based materials.

CNC operators cutting layered board stock

The compression profile suits users who need clean top and bottom edges on plywood, particleboard, density board and solid wood without separate roughing and finishing passes. Hobbyists without a rigid CNC router or dust extraction may find the tools chatter or load up, so they should consider standard up-cut or down-cut bits instead.

4 mm shank diameter

Every cutter in the pack shares a 4 mm shank, so the collet or tool holder must accept that exact size. If the machine spindle requires a different shank diameter the set cannot be used without an adapter, which is not included.

Questions about this item

When will the 4x22mm DLC carbide cutters need replacement?

Replace the cutters when the DLC coating wears through and the tungsten steel edges dull, which shows as tear-out on plywood or density board.

What limits continuous cutting with these two-flute spiral mills?

Heat buildup in the tungsten steel body is the first limit; sustained feed rates that overheat the flutes will degrade the DLC layer and reduce edge life.

How much heat and noise do the cutters generate during all-day CNC routing?

The cutters themselves run silently; all audible noise and heat come from the spindle and workpiece, so manage spindle speed and chip evacuation to control temperature.
