135° point angle with chamfering adjustment enables quick drilling while saving time during marking out. Made from the highest class HSS steel with 5% cobalt, it offers high resistance to temperature. Suitable for drilling in high alloy, titanium, acid-resistant, stainless, and creep-resisting steels, as well as cast iron (durability above 900 N/m2) and other difficult-to-process materials. Drills are made entirely by grinding, ensuring high accuracy and rectilinearity of holes. Packed and sold in a plastic rectangular tube: dimensions 0.5 - 8.0 mm contain 10 pieces; dimensions 8.1 - 13.0 mm contain 5 pieces; dimensions 14 - 20.0 mm contain 1 piece.
