Up-Down Compound Router Bit

The YINGHUA carbide mill cutter is a one-flute compression spiral bit designed for CNC routing. It cuts acrylic, PVC, density board and wood board with a clean top and bottom surface. The tool suits workshops needing precise edge quality on double-sided laminates.

Sustained Cutting Behaviour

Tungsten steel construction maintains edge hardness during extended passes through dense panel materials. The up-down flute geometry continuously evacuates chips toward the centre, reducing heat buildup in the cut zone. This allows consistent feed rates without frequent pauses for chip clearance.

Setup Checks Before Ordering

Verify your CNC spindle accepts a 4 mm shank and provides enough Z-travel for the 55 mm overall length. Confirm the collet or chuck can clamp the 32 mm cutting length without interference. Ensure your machine and work-holding are rated for industrial cutting only, as the tool is not for use by anyone under 18 years old.

Questions about this item

How much heat does the 4 mm carbide flute generate when routing dense board all day?

Tungsten-steel construction and the single-flute geometry evacuate chips quickly, keeping the cutter cooler during continuous passes in acrylic, PVC or wood.

What collet size must my CNC spindle accept for the 4 mm shank?

The tool has a 4 mm shank, so the machine needs a 4 mm collet or a compatible reducer sleeve to hold it securely.

Will the 55 mm overall length clear the gantry on my older desktop CNC router?

At 55 mm total length the bit fits most hobby and light-industrial gantries, but verify your Z-axis travel before purchasing.
