COFA: Cross Hole Deburring
Swiss Precision Since 1961
About The COFA Tool
The HEULE COFA tool is the industry-standard solution for automated cross-hole deburring. Designed for CNC machining, COFA efficiently removes burrs on both front and back edges—even on sloped, uneven, or contoured surfaces—eliminating manual finishing and improving cycle time and consistency across every bore.
A Solution for Cross-Hole Deburring of Sloped, Uneven, and Contoured Bores
For many cross-hole deburring applications, the HEULE COFA tool is the industry standard for replacing manual deburring. Designed for CNC machining, COFA efficiently removes burrs on both front and back edges — even on sloped, uneven, or contoured surfaces — without reversing the spindle or repositioning the workpiece.
By eliminating manual finishing, COFA improves productivity, reduces cycle time, and ensures consistent, repeatable results across high-volume production environments. It’s particularly effective in situations where cross holes prevent the use of standard deburring methods.
Typical cross-hole deburring applications for COFA include:
- Sloped or angled surfaces
- Uneven and even bore intersections
- Crossing bores with limited penetration angles
