VEX-S – The combined drilling and chamfering tool

Efficient combination of drilling, front and back chamfering in One Operation in the range of Ø5.0 - 11.5 mm.

The VEX-S tool combines a replaceable solid carbide high performance twist drill 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 helical carbide drilling tips with material-specific cutting geometries and coatings, with or without inner cooling. 
  • Manually exchangeable carbide chamfering blade with material-specific coating. 
  • For bores from diameter 5.00 mm to 11.50 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 screw-on high-performance helical drill bit. Drilling is followed by front and back chamfering using 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 in One Operation. As soon as the defined chamfer thickness has been achieved, the SNAP radially enters the tool body. The chamfer thickness and 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 by the spring-loaded control bolt to its home position.
