Application Details

  • Through bore: Ø14.0mm
  • Counterbore forward: Ø36.0 mm
  • 60° Sinking forward on the bore: Ø14.0 mm
  • Back chamfer: 1.0 mm x 45º
  • Material: aluminium


The solution from HEULE is a VEX-P combined drill and countersink tool which has been specially adapted for the customer. In one pass and without any further tool change the four form elements can be machined.

The back deburring is executed by the proven SNAP principle.
For the forward counterbore a WSP plate made out of carbide is used.

Machining parameters:
Drill operation:
Speed 3500 rev/min, cutting speed vc 155 m/Min, working feed 0.3 mm/rev

Sinking forward / chamfering backward:
Speed 2800 rev/min, cutting speed vc 140 m/min, working feed 0.1 - 0.15 mm/rev
