Precision CNC Router Bit for Multi-Material Cutting
This tungsten-steel carbide mill cutter is designed for CNC machinery, delivering a precise and easy cutting experience. Its up-down compound single-flute spiral geometry produces clean edges on both faces of the workpiece. It is intended for operators routing acrylic, PVC, density board and wood board in a professional workshop environment.
Replacing Worn Single-Direction Bits
The compression-style flute replaces standard up-cut or down-cut bits that leave tear-out on one surface, making the upgrade worthwhile when finish quality on both sides matters. It suits jobs where changing bits between materials slows production, as one tool handles the listed board types. It is not for users needing multi-flute tools for higher feed rates or for cutting metals and stone.
Sustained Cutting Stability
The solid carbide construction maintains sharpness during extended routing sessions, resisting heat buildup better than high-speed steel alternatives. The single-flute design evacuates chips efficiently to prevent clogging in deep slots or long profiles. Industrial-use-only rating means it is built for continuous machine operation rather than occasional hand-held use.

Questions about this item
Will the 4 mm shank fit my CNC router collet?
The cutter has a 4 mm shank diameter that fits 4 mm collets or ER collets with a 4 mm bore.
How do I avoid chipping when I start the cut?
Ramp or plunge into the material instead of feeding straight in; the up-down flute geometry compresses the top and bottom surfaces only when the tool is fully engaged.
When should I replace this carbide cutter?
Replace it when the cutting edges show visible rounding, the tool begins to burn wood or acrylic, or vibration increases noticeably during routing.
