The spiral drill bit from Alpen is a versatile tool characterized by high elasticity and toughness. It has been specifically designed for use in handheld drills and is excellent for processing both alloyed and unalloyed steel. Thanks to its sharp cutting edges, only a minimal feed is required for larger diameters, which increases efficiency during drilling. The partial hardening of the flute length allows for a 30% faster processing time and a threefold longer service life compared to conventional drills. With a point angle of 118° and a conical ground taper, this drill bit 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 bit is available in a practical packaging unit of 10 pieces and is ideal for professional applications as well as for DIY needs.
