The angle of the blade is appropriate to the machinability of the material being worked on. Benefits: strong main cutting edges, insensitive to impact and lateral forces. Straight cut, can be sharpened by hand. conical grind Apex angle: 118° standard. Edge grinding: tapered. Material: HSS high-speed steel Refined. DRILLS FOR METAL HSS (with shear correction) Ground and sharpened edges allowing these drill bits to be used for all drilling in steel, non-ferrous metals, plastics. Double-walled cut. conical grind The apex angle - 135O with shear correction allows for fast drilling while saving time during scoring. Material: HSS high-speed steel refined. DRILLS FOR METAL HSS (with shear correction) Drill bits made entirely by grinding - guaranteeing high accuracy and straightness of the holes and several times higher productivity than for cylindrical or ground drills. Material - top grade HSS high-speed steel Increased wear resistance. Increased resilience and resistance to torsional stress. double-walled cut Apex angle of 135° with shear correction - enables fast drilling while saving time when scoring . Material: high-speed HSS steel refined. DRILLS FOR METAL HSS Co. Drills made entirely by grinding - guaranteeing high accuracy and straightness of the holes. Material - premium HSS high-speed steel, refined with cobalt for increased performance. For drilling in high-alloy steel, titanium, acid-resistant steel, stainless steel, heatresistant steel and cast iron (strengths above 900 N/m2) and other materials difficult to machine. double-walled cut Point angle of 135° with chamfer correction - enables fast drilling while saving time time during scoring. High temperature resistance. Material: HSS high-speed steel, refined with cobalt Co. DRILLS FOR METAL HSS TiN Drill bits made entirely by grinding, coated with titanium nitride to increase drill bit life and improve hole finish double-walled cut Point angle of 135° with chamfer correction - enables fast drilling while saving time time during scoring. Material: HSS high-speed steel coated with titanium nitride TiN.
