Drilling, deburring and chamfering all at once – how it works

With HEULE’s combination tools, a single tool performs several machining steps. Whilst the drill bit creates the required bore in the workpiece, the integrated chamfer or deburring blade deburrs both sides of the bore edge in the same operation. No tool changes, no turning, no additional process steps: the workpiece comes off the machine ready to use. This not only saves machine time but also reduces the need for manual intervention and thus potential sources of error. The result is consistently high machining quality, making it perfectly suited to series production.

HEULE's combination drilling tools simplify production processes by combining drilling with deburring, chamfering or countersinking.

More about HEULE

A combination drilling tool is a precision tool for CNC machining that performs drilling and chamfering (or drilling and deburring) in a single operation. HEULE combination drilling tools such as VEX and DCC are specially designed to create both sides chamfers simultaneously as the bore is drilled – without having to turn the workpiece or stop the spindle.

Whilst the drill bit creates the bore, the integrated chamfering or deburring blade performs the deburring. First, the front of the bore is deburred; as the tool retracts, the back side is machined. All this is done automatically in a single operation. The workpiece does not need to be re-clamped, re-positioned or turned.

The main advantage lies in the reduced process times achieved by combining several work steps. As there is no need for tool changes, turning or spindle stops, several process steps are eliminated. This can lead to significant cost savings, particularly in series production, such as for brake discs or crankshafts.

Both the VEX and the DCC are tooling solutions in which HEULE has permanently integrated the chamfering technology into a drill body. In the case of the VEX, this is done with a replaceable drill insert; for the DCC, it is integrated into a solid carbide drill bit. With the Module Line, on the other hand, your existing drill body is supplemented with a chamfering module to maximise time savings and ensure the highest quality.

HEULE’s combination drilling tools are suitable for all common materials used in CNC machining – from aluminium and steel to stainless steel. The carbide chamfering cutters are coated to suit the specific material and can be selected according to the material being machined.

Yes. If the standard tools do not meet the requirements of your specific application, HEULE will work with you to develop a customised combination tool, for example in combination with countersinking. As experienced problem-solvers, we analyse your bore geometry, materials and process requirements and develop a solution that fits perfectly. Please contact us via the enquiry form.
