DCC | Solid carbide drill bit with chamfering

Range

The DCC can be used for diameters from 4.0 mm to 10.0 mm. Drilling depths of up to 2.5 x drill diameter are possible. The integrated chamfering blades are available in forward and backward cutting or backward cutting only. Depending on the application, chamfering capacities of up to 0.8 mm are possible. The blades and drills are designed specifically for the application. If larger chamfers are required for forward machining, countersink steps can be integrated.

Construction

The DCC tool has a carbide drill body. The blade for forward and backward chamfering is based on SNAP technology and is made of coated carbide. The mechanical, spring-loaded function principle ensures a reliable process and simple blade changes.

Process steps description

In just one work step, the DCC creates a bore with a chamfer on both sides. The big advantage: This process takes place without turning the workpiece and without changing tools.

In the first step, the solid carbide drill provides the bore. Chamfering is then carried out on both sides using the SNAP technology chamfering blade. The desired chamfer is created in the forward working feed. Upon reaching the defined chamfering capacity, the blade moves radially into the tool body. When exiting the bore, the spring-loaded control bolt returns the blade to its starting position so that the chamfer can be created on the back.
