Precision CNC Router Bit for Wood and Composites
The YINGHUA 3.175X22X45mm Rainbow 3A UP DOWN Compound Single Flute Spiral Carbide Mill Tool Cutter is designed for CNC machinery requiring precise material removal. Its tungsten steel construction supports accurate cutting across a range of sheet goods. This single flute bit suits operators focused on clean edge quality in wood-based panels and plastics.
Up-Down Shear Geometry Reduces Tear-Out
The compression spiral combines up-cut and down-cut flutes to pull chips away while pressing the workpiece faces down. This action minimises splintering on both the top and bottom surfaces of acrylic, PVC, density board and wood board. The single flute design promotes efficient chip evacuation during high feed rates.
Solid Carbide Shank Withstands Industrial Loads
The 3.175 mm shank diameter fits standard collets and tool holders used in benchtop and production routers. Solid carbide resists deflection and heat buildup during extended cutting cycles in abrasive composites. Safety guidance restricts use to persons over 18 years old in industrial cutting applications only.

Questions about this item
When will the 3.175 mm single-flute carbide cutter need replacing?
Replace the bit when the up-cut and down-cut edges no longer shear acrylic, PVC, density board or wood cleanly, or when visible chipping appears on the tungsten-steel flutes.
What stops a continuous cut in dense board with this 45 mm overall-length tool?
Heat buildup in the solid-carbide body and chip packing in the single flute are the first limits during prolonged routing.
How much noise and heat does the rainbow-coated 22 mm cutting-length bit produce in all-day CNC use?
Expect typical high-speed router whine and noticeable heat at the shank; the coating reduces friction but does not eliminate thermal load.
