SNAP18 Module

Your drill body. Our chamfering module. Your time-saving. 

  • Perform both drilling and chamfering at the same time in just one operation
  • Reduce the number of individual tools and working steps and thus process times and costs
  • Available for drill bodies starting from drill-Ø 18.0 mm
  • Module dimensions: 16.0 x 3.5 x 5.0 mm
  • Can be installed close to the drill head due to the compact size of the module

The new SNAP module is used in drill bodies from Ø18.0mm. Despite its small dimensions, the SNAP module produces chamfers ranging from 0.5 to 1.0mm – depending on the blade used. The blades are available with various coatings depending on the workpiece material and can be exchanged in just a few quick steps using an assembly tool.

The compact design of the module has very few wearing parts. The module is extremely compact at just 16.0 x 3.5 x 5.0 mm. 

To accomodate the SNAP module, the existing drill body is to be modified with a pocket by the customer (in consultation with the drill body manufacturer). The module is fixed to the drill body with a single screw. To enable higher feed rates and further optimise the process time, two modules can be integrated in one drill body. It is not possible to integrate the modules into solid carbide drills. 


Due to the compact size of the chamfering module, it can be installed directly behind the drill head. This reduces traverse distances, allows drilling and chamfering to be carried out simultaneously, enables longer drilling depths and reduces obstruction by chips during chamfering.

Process steps

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


The existing drill body is used for drilling.During drilling the integrated SNAP Module 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.


The blade automatically retracts due to its geometry when the chamfering size is reached. Inaccurate workpieces such as castings with their typical tolerance variations can now be machined reliably and with a consistent chamfering result.
