kwb HSS Metal Drill Bit Diameter 20 mm with Twisted Shank, Thread Rolled, 118 Point Angle, Accessories

The roll-rolled HSS metal drills with twisted shaft are precision tools according to DIN 338 for excellent dimensional accuracy of the bore. The blue-black metal drill bits correspond to the drill type N with a normal spiral for medium length chipping material. The roll-rolled steel drills are manufactured by heated metal round rods, which are pressed into their typical spiral shape by rollers and transport the chips when drilling. The twisted round shank of the twist drill is ideal for use with large diameters in standard drills. The steel drill bits have a 118° point angle and are suitable for easy drilling work in alloy and non-alloy steel, grey cast iron, non-ferrous metals and hard plastics.
