Range

The standard range includes tools for bore diameters from 5.0 mm to 11.5 mm. They are available in versions with a drilling depth of 1xd or 2xd. The corresponding drill insert bits are available in 0.1 mm diameter increments. The blades for chamfering correspond to the SNAP5 series. These are available from a diameter of 5.5mm x 90° in 0.5 mm increments and in forward and backward cutting or backward cutting only versions. The chamfer size and angle are geometrically defined on the blade and can only be changed by using a blade with a modified geometry.

Construction

The VEX combination tool features an threaded twist drill insert tip and a SNAP technology blade integrated in the tool body for front and back chamfering. Both the drill insert tip and the blade are made of coated carbide and are extremely simple to change. The chamfering blade is accurately positioned by a spring-loaded control bolt in the tool body.

Process steps description

In a single operation with the VEX, the bore is produced with chamfers on both of its edges. This process is completed without rotating the workpiece or changing tools.

 

The high-performance twist drill insert takes care of the drilling. After drilling, the integrated SNAP chamfering system is used to chamfer the front and back edges. The desired chamfer is created by the blade in working feed. Upon reaching the defined chamfering size, the blade retracts radially into the tool body. When exiting the bore, the spring-loaded control bolt returns the blade to its neutral position so that the chamfer can be machined on the back edge of the bore.
