Drills made of roll forged High Speed Steel HSS are suitable for general drilling tasks. They replace drills made of conventional tool steel because they have better properties, such as up to four times higher cutting speed
The drills are suitable for steels, cast steel (alloyed), cast steel (unalloyed), grey cast iron, malleable cast iron, nodular cast iron, sintered iron, nickel silver, graphite, bronze, brass, aluminium
The cutting direction is right and the point angle is 118°. DIN 338. Cylindrical shank
Twist drill bits with cylindrical shank are suitable for use in all drill chucks and have ideal self-centring properties
The design with reduced shank makes it possible to use drills that have a larger diameter than the matching drill chuck. This makes the twist drill bit suitable for all common hand drills
