YINGHUA 3.175 mm carbide router bit

This single-flute compression cutter is designed for CNC routing of wood, acrylic, PVC and density board. The up-down spiral geometry shears both faces of the workpiece to reduce tear-out on double-sided panels. Tungsten-steel construction provides wear resistance for extended tool life. Supplied as a single new cutter ready for industrial use.

For CNC operators cutting sheet goods on desktop

The 3.175 mm shank suits machines with matching collets and the 55 mm overall length fits typical Z-travel envelopes. Buyers who need multi-flute tools for faster chip evacuation or larger shank diameters for heavy-duty spindles should look at other tooling. Not intended for handheld use or for cutting metal, stone or hazardous materials.

3.175 mm shank diameter

This dimension determines whether the bit fits your machine's collet or tool holder. Verify the shank size against your spindle specification before purchase. The 32 mm cutting length and 55 mm overall length define the maximum depth of cut and tool clearance. No other specification overrides this fit requirement.

Questions about this item

When will the 3.175 mm shank carbide cutter need replacement?

Replace the cutter when the up-down spiral flutes show visible dullness or chipping that degrades cut quality in acrylic, PVC, density board or wood board.

What limit appears first during continuous CNC routing with the 55 mm overall length tool?

Heat buildup in the tungsten-steel body and single-flute geometry becomes the limiting factor before the 32 mm cutting length reaches its wear limit.

How much noise and heat does the 3A up-down compound cutter generate in all-day operation?

The single-flute carbide design runs quieter than multi-flute bits; heat stays manageable with proper feed rates and chip evacuation in wood and plastic.
