This cutter can handle very high feed rates thanks to a rigid design and the two effective numbers of teeth.
The insert and body strength gives the cutter maximum safety and reliability, which makes it suitable for use in unmanned production. R218.20 can handle very high feed rates which gives it very good productivity on modern machine tools.
It is also cost-effective under peak performance thanks to the insert and body strength. The new Ball Nose cutter R218.20 is a versatile cutter and can be used from semi-finishing to heavy roughing operations.
The cutters have a unique seating with tenon to avoid stress on the locking screw, and a chip space with a big radius to make the cutter strong in the centre.
The insert edge is "S" curved to reduce cutting forces, and has a constant cutting rake all along the edge. Reinforcement in the centre makes it breakage resistant.
Cutters are available in Cylindrical shank, Cylindrical/Weldon shank, Seco Weldon shank, Morse taper, Weldon pin drive shank (dia 50 mm) and Combimaster heads, with different reach lengths.
