YINGHUA carbide mill cutter for CNC routers

This new YINGHUA carbide mill cutter is a single-flute up-down compression bit built for CNC routing. The tool measures 3.175 mm in diameter with a 25 mm cutting length and 50 mm overall length. It is made from tungsten steel for hardness and wear resistance.

Suited for cutting acrylic, PVC.

The cutter is intended for industrial cutting on materials such as acrylic, PVC, density board and wood board. It is not for buyers who need multi-flute geometry for chip evacuation in deep pockets or for operators under 18 years of age.

Single-flute up-down compression geometry

The defining specification is the one-flute up-down compound spiral that produces a compression cut on both faces of the workpiece. This geometry decides whether the bit matches the required finish quality on the materials listed.
