CNC Router Bit Set

This set supplies ten solid-carbide router bits for CNC milling and engraving work. The two-flute straight-slot geometry suits wood, plywood, acrylic, PVC, nylon and resin. Tungsten steel construction gives wear resistance for repeated production runs. The pack is intended for industrial cutting use only.

Tungsten Steel Build

Each cutter uses tungsten steel for hardness and edge retention during abrasive material removal. The straight-slot profile allows direct plunge and side milling without specialised tool holders. Double flutes evacuate chips efficiently in plastics and soft woods. The 10-piece box keeps spares on hand for batch jobs.

Application Limits

Cutting performance is limited to the listed non-ferrous materials; metals and hazardous substances are excluded. The bits are not for use by anyone under 18 years of age. Shank and flute dimensions restrict the maximum depth and width of cut per pass. Users must match feed rates and spindle speeds to the specific workpiece.

Questions about this item

What shank diameter does the 4X4X25X45 bit use, and what collet size does that limit me to?

The 4 mm shank fits a 4 mm collet, so the bit is limited to machines that accept 4 mm tooling.

What is the overall length of each cutter, and will it clear my 45 mm Z-travel?

Each bit measures 45 mm overall, so it needs at least 45 mm of clear Z-travel plus the collet length.

How do I secure the 10-piece set in an ER collet without the flutes slipping?

Insert the 4 mm shank until the flutes are just outside the collet face, then tighten the nut to the maker's torque spec.
