Alpen HSS Cobalt Drill Bit - 9.0mm - ALP62309

Alpen HSS Cobalt Drill Bit 9.0mm (ALP62309) is a professional-grade jobber drill made for demanding metalworking tasks. This single-pack 9.0 x 125/81 mm drill features a 5% cobalt alloyed high-speed steel construction for excellent heat resistance and long life when drilling hard materials. It is designed for steels with tensile strength over 800 N/mm and is especially suitable for high-alloy steels, bearing steels, hot and cold rolled steel, and stainless steel.

The special point shape gives highly accurate, self-centering starts for cleaner holes and reduced walking. Precision grinding promotes fast drilling progress and can require up to 50% less feed pressure in many applications. The bit withstands high thermal stress up to 600 and maintains performance under heavy use. Manufactured in Austria, this Alpen drill offers reliable build quality for tradespeople and serious DIY users who need consistent, repeatable results when working with tough metals.

Use this Alpen HSS cobalt drill for general metal drilling, stainless steel jobs, and any situation where higher heat resistance and durability are required. Packaged as one drill, it is an easy addition to a professional toolkit or a targeted replacement for worn bits.
