HEULE X-BORES
Automated Solutions for Cross-Hole Deburring

 

With X-BORES, HEULE delivers an advanced, automated approach to cross-hole deburring—eliminating the need for manual finishing while ensuring precision, repeatability, and consistency in every cycle. Engineered for modern CNC machining, HEULE X-BORES excels at deburring intersecting holes, sloped bores, and 1:1 cross-bore ratios with unmatched reliability and efficiency.

 

By automating the cross-hole deburring process, manufacturers can achieve:

  • ⏱️ Reduced cycle time and lower labor costs
  • ⚙️ Consistent, high-quality edge finishes
  • 🧭 Greater process reliability in both standard and complex part geometries

 

Backed by Swiss engineering and decades of application expertise, HEULE provides customized deburring solutions trusted by manufacturers in aerospace, automotive, and precision engineering industries worldwide.

 

Consult with an Application Engineer to find the best X-BORES solution for your specific geometry and material.

COFA


A Solution for Cross-Hole Deburring of Sloped and Uneven Bores

 

For many cross-hole deburring applications, the HEULE COFA tool is the trusted alternative to manual deburring. Designed for CNC machining environments where parts are difficult or time-consuming to hand-deburr, COFA delivers consistent, repeatable results on sloped, uneven, and intersecting bore edges.

 

By automatically removing burrs on both sides of the bore, COFA improves productivity, reduces cycle time, and enhances overall part quality—especially in components 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

COFA-X

 

A Solution for Cross-Hole Deburring of 1:1 Ratio Cross Holes

 

For machining environments where cross holes are identical or nearly identical in diameter, the HEULE COFA-X tool delivers precise, repeatable deburring results. It’s specifically designed for situations where traditional deburring tools can’t reach or where manual deburring would compromise part quality.

 

By automating cross-hole deburring, COFA-X ensures consistent edge quality and process reliability—especially in parts where bores merge, intersect, or create limited tool access.

 

Typical cross-hole deburring applications for COFA-X include:

  • Bores with identical or nearly identical diameters crossing each other
  • Bores that merge into one another
  • Crossing bores with center-axis offset or interfering edges that block direct tool access

SNAP-X


A Solution for Cross-Hole Deburring of Main Bores with Intersecting Bores

 

The HEULE SNAP-X tool is built for complex main bore deburring applications where multiple cross bores intersect the primary bore. Designed for precision and speed, SNAP-X automates the removal of burrs at intersecting cross-bore junctions—improving surface finish and maintaining tight dimensional accuracy.

 

By streamlining what would otherwise be a manual finishing process, SNAP-X enhances productivity, reduces cycle time, and ensures consistent results across multi-bore configurations.

 

Typical cross-hole deburring applications for SNAP-X include:

  • Intersecting cross bores that leave sharp internal edges
  • Main bores that serve as central passages with several intersecting cross bores
