HSS PRO is an industrial quality helical Bit with high performance and high durability. It is designed for Biting steel and cast steel, cast and unformed steel, cast iron, non-ferrous metals, plastics and other materials. The 118 ° split point allows perfect centering when Biting and a higher Biting speed. Requires less pressure than standard HSS Bits.
- 118 ° split point with higher performance and optimum centering, precision Biting, without the need for pre-Biting or using a pilot Bit, penetrates quickly, requires less effort and pressure;
- Great resistance. Low risk of breakage even when Biting with smaller diameters due to high elasticity;
- Great Biting performance. Even under unfavorable working conditions;
- Great accuracy. Low tolerance limits and high concentricity for maximum accuracy;
- Best quality steel. High performance steel and high speed.
