The VEX 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. Like the cutting edge for forward and reverse chamfering, the drill tip is made of coated carbide and is very easy to change. High efficiency is guaranteed.
- 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.
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.

As standard, VEX-S tools are available for bores from Ø 5.00 mm to Ø 11.50 mm with bore depths of 1 times diameter and 2 times diameter. VEX-S drilling tips are available from Ø 5.0 mm in 0.1 mm increments. Intermediate sizes and other dimensions upon request.
The chamfering blades correspond to the SNAP5 series. They are available from Ø 5.5 mm x 90° in 0.5 mm increments for front and back or only back cutting. Other dimensions upon request.
