The Alpen HSS Cobalt Drill Bit Set offers professional-grade cutting precision and high durability for the toughest materials. This 25-piece kit includes bits from 1mm to 13mm in 0.5mm increments, giving you full coverage for all metal drilling tasks.

Built for Hard Metal Applications

Each drill bit is made from high-speed steel combined with 5% cobalt, which increases heat resistance and extends lifespan. Because of this design, the bits stay sharper for longer and resist wearing out under high pressure.

In addition, the split-point tips allow you to drill directly into the surface without walking or requiring pilot holes. As a result, your work becomes more efficient and precise.
