RF 100 Speed P has a 48° helix angle with unequal cutting-edge partitioning that is said to ensure a soft, quiet cut and smoothness in machining. This capability reduces the load on the machine and increases the MRR performance. In addition, the optimised chip gullet with a deep flute in the front cutting-edge area, brings about improved chip evacuation when ramping and helical plunging.

Under HPC (high-performance cutting) conditions, the entire length of the cutting edge was used with a small cutting width (5-15% radial depth of cut). Feed per tooth was 0.5 mm during the record attempt. With four teeth, this meant 2 mm feed per revolution.

This performance should be of interest to companies that have large quantities of steel to cut, including the tool and mould-making industry, where mainly high-tensile steels are found, but primarily aerospace, where lightweight components made of solid material with a material removal rate of up to 96% are produced. Of course, the special cutting-edge geometry can also be put to good use in the automotive industry.

Further cutting data from the successful record attempt, which deployed a 20 mm diameter cutter (HSK 63) included: 450 m/min cutting speed; 7,162 rpm spindle speed; 1.2 mm radial depth of cut (6%); 63 mm axial depth of cut; and 14,324 mm/min feed speed.
