Broaches KERFOLG for hexagona holes A16
The broach for polygonal holes is a specially shaped tool that is fixed to the spindle of the broaching head on one end, while the other end bears the shape of the hole to be obtained. The broaches are manufatured from special HSS steels, duly treated so that they can also be used to machine hard metals. Before starting with the broaching operation, a pre-broach hole must be drilled on the work piece. This pre-broach hole should be a little bit bigger than the shape to machine (from 0,1 to 0,3 mm bigger) and a little bit deeper in order to discharge the chips. It is a good habit of using a good cutting oil during the broaching operation.

Broaching heads KERFOLG for polygonal holes and external surface profiles
The Broaching Head is a high-speed tool for forming blind or through holes with regular polygonal shapes (square, hexagonal, TORX®, spline, etc.). Installing an adaptor on the same broaching head, polygonal surface profiles can be realized. The broaching head may be applied on most rotary machine tools, both conventional (lathe, drill, milling machine) and numerically controlled ones. Thus it can work both vertically and horizontally. The broach seat is set in the tool body at a specific inclination so that, when the machine rod starts to rotate, it transmits both, a rotary and oscillating motion to the broach. The combined action deriving from the rotation and feed function provided by the machine, allows the broach to smoothly penetrate the pre-drilled work-piece, in order to form the shape required.
