The Sprint Master DIN 338 RN spiral drill bit from Alpen is a versatile tool known for its high elasticity and toughness. It has been specifically designed for use in hand drills and is excellent for machining both alloyed and unalloyed steels. With a diameter of 19.5 mm and a reduced shank of 12.5 mm, this drill bit offers an optimal combination of performance and efficiency. The sharp cutting edges enable precise machining, while the special conical surface grind and a tip angle of 118° enhance cutting quality. Thanks to the partial hardening of the flute length, the drill achieves up to 30% faster machining speeds and three times longer tool life compared to conventional drill bits. Its robust construction ensures maximum torsional rigidity, improving handling and control during the drilling process.

• High-quality HSS material for durability and efficiency
• Partial hardening of the flute length for improved tool life
• Suitable for machining alloyed and unalloyed steels
• Optimized conical surface grind for precise cuts.
