The spiral drill from Alpen is a versatile tool characterized by high elasticity and toughness. It has been specifically designed for use in hand 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 allows for processing that is 30% faster and a threefold longer service life compared to conventional drills. With a point angle of 118° and a tapered shank grind, this drill offers optimal cutting performance and is particularly break-resistant. The precise manufacturing and the use of high-quality HSS steel ensure high quality and durability, making it an ideal choice for professional applications.

• High elasticity and toughness for reduced breakage risk
• Optimized drill geometry for shorter drilling times
• Partial hardening of the flute length for longer service life
