5-Piece Carbide Mill Cutter Set

This set contains five spiral carbide end mills designed for CNC router work. Each cutter measures 3.175 by 17 mm and features a DLC coating. They are intended for woodworking professionals and hobbyists who need reliable tooling for compression cutting tasks.

Up-and-Down Compression Flute Geometry

The defining specification is the up-and-down cut two-flute spiral design. This geometry pulls chips upward on the top flutes and downward on the bottom flutes to compress the material and prevent tear-out on both faces of the workpiece.

Tungsten Steel Construction With DLC Coating

Cutters are made from tungsten steel for hardness and wear resistance when machining wood, plywood, density board, solid wood and particleboard. The DLC coating further reduces friction and extends tool life. Note that these bladed tools are not for use by persons under 18 years of age.

Questions about this item

What does the 3.175 mm shank diameter mean for my CNC router collet?

The 3.175 mm shank matches a standard 1/8 inch collet size, so it fits directly into many desktop CNC routers without needing an adapter or reducer sleeve.

How does the up-and-down cut geometry affect the edges when routing plywood or solid wood?

The compression spiral pushes chips both upward and downward, which shears the top and bottom faces cleanly and reduces tear-out on double-sided veneers or laminates.

What physical clearance do I need for the 17 mm cutting length on my machine?

The 17 mm flute length requires at least that much Z-axis travel below the collet face, so check your router's maximum plunge depth before starting a deep profile cut.
