Description
Set of cylindrical shank drill bits made from HSS 4241. Thanks to their titanium nitride coating, they dissipate heat very efficiently and do not dull when working in hard steels. The blade's 135° angle of attack, the so-called split point, allows drilling even without first using a Center punch. Manufactured to DIN 338 for professional use in industry. Cylindrical shank drill bit designed for standard self-clamping and keyed drill chucks. The drills enable work in stainless steel, acid-resistant steel, cold-rolled steel.
The set includes 99 drill bits in 14 sizes.
