The spiral drill from Alpen is a versatile tool characterized by high elasticity and toughness. It has been specifically designed for use in hand-held drills and is excellent for machining both alloyed and unalloyed steel. Thanks to its sharp cutting edges, only a minimal feed is required for larger diameters, which increases drilling efficiency. The partial hardening of the flute length ensures a 30% faster machining process and a three times longer service life compared to conventional drills. With a point angle of 118° and a tapered ground tip, this drill offers optimal cutting performance and is particularly break-resistant. The precise manufacturing and the use of high-quality HSS steel guarantee high quality and durability, making it an ideal choice for professional applications.

• High elasticity and toughness for reduced breakage risk
