VEX-P – The combined drilling and chamfering tool

Efficient combination of drilling, front and back chamfering in One Operation in the range of Ø11.0 - 17.0 mm.

The VEX-P tool combines a replaceable solid carbide high performance drill insert with HEULE's economical SNAP chamfering system to enable drilling and front and back chamfering in a single process.

Specifics/Benefits

  • Reduction of process times by performing two machining operations in One Operation. 
  • Easy-to-exchange carbide drilling plates with material-specific cutting geometries and coatings. 
  • Manually exchangeable carbide chamfering blades with material-specific coatings. 
  • For bores from diameters 11.00 mm to 16.99 mm and bore depths up to 2 times diameter. 
  • Short set-up and idle times due to easy handling.

Function

For drilling work, the tool is equipped with a drilling bit. Drilling is followed by front and back chamfering with the integrated SNAP chamfering system. The SNAP chamfering blade is held by a spring-loaded control bolt in the tool body allowing it to move. The specially ground SNAP blade for front and back or only back cutting produces the required chamfer by forward feed. As soon as the defined chamfer thickness has been achieved, the SNAP blade radially enters the tool body. The chamfer thickness and chamfer angle are geometrically defined on the SNAP blade and can only be modified by inserting a SNAP blade with different specifications. When it exits the bore, the SNAP blade is returned to its home position by the spring-loaded control bolt.
