Tungsten steel router bit for CNC wood

This single-flute carbide cutter is designed for CNC machinery and handles wood, plywood, density board, solid wood and particleboard. The up-and-down spiral geometry compresses material during cutting to reduce tear-out on both faces. It is intended for industrial use only and not for anyone under 18 years of age.

Compression spiral limits chip evacuation in deep

The opposing helix directions pull chips toward the centre of the cut, which works well for through-cuts in sheet goods but can trap debris in blind pockets or deep grooves. The 3.175 mm shank diameter restricts the tool to collets or chucks that accept this exact size, so spindle compatibility must be verified before use.

Solid carbide construction resists wear

Tungsten steel retains its edge longer than high-speed steel when machining particleboard or fibre-reinforced plastics, reducing the frequency of tool changes. The single-piece package delivers one cutter ready for immediate mounting, with no additional hardware or collets supplied.

Questions about this item

Should I choose the 3.175 mm shank version or a different diameter for my CNC collet?

The cutter has a 3.175 mm shank; select this version only if your collet or holder is sized for 3.175 mm, otherwise choose a matching diameter.

What does the 25 mm cutting length mean when the bit is in the spindle?

You can plunge or profile up to 25 mm deep in a single pass before the shank contacts the workpiece.

How does the up-down spiral geometry affect chip evacuation in wood and PVC?

The opposing flutes push chips both upward and downward, compressing the material and reducing tear-out on both faces during compression cuts.
