BOSCH METAL DRILL SET

This Bosch drill bit set offers a reliable solution for drilling into metal. It contains 19 drill bits made from high-speed steel (HSS) alloyed with cobalt, making them suitable for alloyed and non-alloyed steel, stainless steel, cast iron, and other heavy-duty materials. A 5% cobalt content ensures the drill bits maintain a long lifespan even under heavy use. The set is designed for use in both portable and pillar drills.

Long lifespan thanks to cobalt alloy

Made from high-quality high-speed steel (HSS) alloyed with 5% cobalt, these drill bits offer exceptional hardness and heat resistance. They retain their sharpness and shape even when drilling into tough materials such as stainless steel or acid-resistant steels. Additionally, the twin-cutter and double-flute design promotes efficient chip removal, ensuring smooth drilling and extending the overall lifespan of the tools.

Active cutting and perfect centring

For maximum precision, each drill bit features a split point design that enables immediate, active cutting without the need for pre-punching. This prevents the bit from slipping across the surface and ensures perfect centring from the start. The 135-degree point angle and precise h8 diameter tolerance help produce clean, accurate holes. The tapered drill bit shape and type-N flute are optimised for efficient metalworking.
