Deburring of oil bores

With X-BORES HEULE advances into uncharted technical territory that has been out of reach so far. Developping the CBD system, HEULE has introduced a new function and work concept.  Bore intersections with a low main bore / cross bore ratio and flat penetration angle become burr free because of a defined cutting process that ensures a complete edge break. In a close cooperation with the customer, our R&D team examines the feasibility and develops a tailor-cut tool for the specific application.

Application situation


  • Classical oil bore with bore diameter Ø5.0 till 10.0 mm 
  • Very complex intersecting bores usually located in toothings or steps
  • Intersecting bores with a very flat penetration angle

Solution approach

The Cross Bore Tool

The Cross Bore Deburring Tool (CBD) has been developed to deburr oil bores. The tool penetrates the cross bore and deburrs the bore intersection in an absolute process-safe manner.

What's next?

Have you got an unsolved deburring issue you would like to resolve with us?

Any viable solution begins with a clear description of the application. Please define your demands and expectations in a comprehensive and detailed manner. Please focus therefor on the following important aspects:

  • Description of the present deburring process
  • Details of the bore and the application
  • Description of the environment: Machine, clamping, fixture, spatial conditions, interfering edges
  • Number of bores to be deburred
  • Cycle time? Present solution? Present time (Actual/Target)?
  • Is there any function assigned to the deburred surface?
  • Description of the desired final result / target description
  • What has to be observed imperatively when designing the new deburring process?
