Compression Spiral Cutter for CNC Wood and PVC

This single-flute carbide mill cutter is built for CNC routers that need clean edges on both faces of the workpiece. The up-down spiral geometry shears fibres upward and downward at the same time, preventing tear-out on laminated boards and soft plastics alike.

Best for CNC operators cutting double-sided sheet

Woodworkers producing cabinet parts, sign makers routing acrylic, and hobbyists milling plywood will benefit from the compression action. Buyers who only need a single-direction up-cut or down-cut bit for through-cuts or pocketing should look at a simpler geometry instead.

3.175 mm shank with 15 mm cutting length

The tungsten-steel body measures 38 mm overall and carries two flutes in a right-hand spiral. That shank diameter and flute length are the decisive figures for tool-holder clearance and depth-of-cut planning.

The cutter has a 3.175 mm shank, so the collet must match that size exactly.

Will this up-down spiral bit cut cleanly in the plywood and solid wood I already use?

Yes, the tungsten-steel flutes are designed for wood, plywood, density board, solid wood and particleboard.

How can I confirm the bit is cutting correctly after installation?

Check for smooth, tear-free edges on both faces of the workpiece and listen for steady, quiet cutting sound.
