130° Parabolic Screw Machine Drills – Cobalt & TiAlN Coated
Features and Benefits
- Wide land parabolic design for drilling holes deeper than 5xD while eliminating the need to “peck”.
- 130° split point to prevent “walking”.
- Heavy-duty parallel web.
- For materials that form long chips, like aluminum, brass and copper alloys.
- Wide flutes with 40° helix angle provide fast chip removal.
- Increased web thickness improves feed rate.
