- TypeRight-Angle Drills
- Up-down spiral cuts clean edges on both faces
- Single flute clears chips fast in acrylic and PVC
- Tungsten-steel carbide keeps sharp edge in dense board
- 175 mm shank fits standard CNC collets
- 28 mm cutting length handles 50 mm deep passes
Tungsten Carbide Compression Cutter
This 3.175 mm shank router bit uses an up-down spiral flute to shear material on both faces. The single-flute geometry clears chips efficiently while the tungsten steel body resists wear during extended CNC runs. It is sold new as a single piece for immediate workshop use.
Right-Angle Drill Compatibility
The cutter fits standard right-angle drill collets accepting a 3.175 mm shank, allowing quick tool changes without specialised holders. Its 28 mm cutting length and 50 mm overall length suit through-cuts in sheet goods up to that depth. The compression action reduces tear-out on laminated surfaces during everyday panel processing.
Upgrade From Single-Direction Bits
The up-down flute replaces conventional up-cut or down-cut bits when both top and bottom edges must stay clean. The jump is worth it for CNC operators cutting acrylic, PVC, density board or wood board where flip-over sanding or edge-banding adds unwanted labour. Not suited for hobbyists restricted by the 18-years-plus safety guideline or for non-industrial hazardous-material cutting.

Questions about this item
What shank diameter does the 3.175X28X50mm cutter need to fit my collet?
The cutter has a 3.175 mm shank, so it fits 3.175 mm (1/8 inch) collets used on many desktop CNC routers.
How much clearance does the 50 mm overall length require inside my machine?
The tool measures 50 mm overall, so the spindle and gantry must allow at least that much Z-travel plus the material thickness.
What is the correct feed direction for the up-down flute geometry?
The up-down spiral pulls chips both ways; run the spindle clockwise and feed forward so the compression action shears the top and bottom faces cleanly.
