Alpen Twist drill

The spiral drill from Alpen is a universal 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 ensures a 30% faster machining process and a threefold longer service life compared to conventional drills. With a point angle of 118° and a tapered ground finish, this drill offers optimal cutting performance and is particularly break-resistant. The use of high-quality HSS steel and a special heat treatment contribute to the product's durability and robustness. The spiral drill is available in a convenient packaging unit of 10 pieces and is ideal for professional applications as well as for DIY needs.
