CNC Router Bit for Compression Cutting

This single-flute carbide milling cutter is designed for CNC machinery and delivers precise cutting across acrylic, PVC, density board and wood board. The up-down compound geometry reduces tear-out on both surfaces during compression wood routing. It suits professional workshops and industrial users who need clean edges on laminated or double-sided materials. The tool is not intended for anyone under 18 years of age.

Tungsten Steel Construction for Heat Resistance

The cutter body uses tungsten steel to maintain rigidity and resist heat buildup during extended routing passes. A single-flute design promotes efficient chip evacuation, which helps keep the cutting zone cooler and lowers the load on the spindle. Normal use produces typical routing noise levels without excessive vibration when the tool is secured correctly in a compatible collet.

Single-Piece Packaging for Immediate Use

The package contains one up-down cut router bit ready for installation in a CNC collet. No additional accessories, collets or software are supplied, so operators must verify shank compatibility with their machine before starting work. The minimal packaging reduces waste and keeps the focus on the cutting performance of the carbide tool itself.

Questions about this item

How do I install the 8 mm shank in a CNC collet and which step causes run-out?

Insert the 8 mm shank fully into a matching collet, tighten evenly and verify the flute clears the workpiece — partial seating causes vibration.

When will the tungsten-steel flute need replacement?

Replace when the single flute shows visible rounding or chipping on the up-cut and down-cut edges — resharpening is not practical for this geometry.

What limit appears first during a long cut in dense board?

Heat buildup at the 35 mm cutting length softens the carbide tip, so feed rate must drop before the 70 mm overall length is fully engaged.
