Drilling combined with front and back chamfering in a single pass Heule VEX is the efficient combination of drilling with the HEULE drill and chamfer technology. One single pass and the bore is complete including the chamfer on both bore edges without a tool change or turning the workpiece. The VEX combination tool features a threaded twist drill insert tip and a SNAP technology blade integrated in the tool body for front and back chamfering. The chamfering blade is accurately positioned by a spring-loaded control bolt in the tool body. The high-performance twist drill insert takes care of the drilling. 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. |
| Bore diameter 5.0 mm – 11.5 mm, drilling depth up to 2xd. Both the drill insert tip and the blade are made of coated carbide and are extremely simple to change. VEX drill geometry limits chip wrapping issues or interference with any mechanical operations of the deburr operations. The single bladed front/back SNAP chamfer blade is easy to use and offers quick change features so the tools never leave the machine. |
