COFA: Cross Hole Deburring

Swiss Precision Since 1961


A Solution for Cross Hole Deburring of Sloped Bores

For many cross hole deburring applications that our customers encounter, COFA is the best solution for replacing manual deburring. In situations where parts are being hand deburred because of the existence of cross holes, a standard COFA tool is often the way to eliminate time and labor, while also producing more consistent, higher quality parts.

Typical cross hole deburring situations for COFA:

  • Sloped surfaces
  • Uneven and even surfaces
  • Crossing bores with limits in respect of the penetration angle
