split point angle. Long lasting working capacity. Short chisel edge for reduced drilling resistance. Suitable for drilling in steel, cast iron, non ferrous metals, alloyed and non-alloyed material. Drill Bit Set made from HSS for high-performance, offering more resistance than high carbon steel bits. It contains a great selection of the most commonly used diameters from 1mm to 13 mm in 0.5 mm increments. These High-Speed Steel (HSS) are constructed from a single piece of high-speed steel, thus reducing breaking and blunting under heat or stress.
Features and Benefits
Ground flute for a longer life than equivalent roll forged bits
The shaft is equal to the diameter of the drill for low breakages
