BOSCH METAL DRILL SET

BOSCH PRO Stainless Steel HSS-Co drill bit set is a professional solution for drilling into various types of metal. Made of high-speed steel with a 5% cobalt alloy (HSS-Co), these drill bits retain high hardness and durability even at high temperatures. This gives them a long service life, especially when working with stainless steel, cast iron or acid-resistant steel. The set is designed for use in both portable and pillar drills, making it ideal for demanding craftsmanship.

Material for demanding applications

High-speed steel (HSS) enriched with a 5% cobalt alloy forms the core of these drill bits. This combination significantly increases resistance to wear and thermal stress generated when drilling hard materials. As a result, the drill bits retain their sharpness and performance for longer, which you will appreciate especially when working with stainless steel or acid-resistant steel. The cobalt alloy ensures reliability even in demanding industrial conditions.

Precision and drilling efficiency

The point design is key to a precise result. The drill bits in this set feature a split point with a 135-degree angle. This geometry enables instant and precise drilling without the need for pre-punching. It also supports active cutting, which reduces the required feed pressure. Two Type N spiral flutes effectively remove chips from the drilled hole, preventing overheating and contributing to a clean finish.

Universal clamping and wide range of uses

Each drill bit in the set features a cylindrical shank with a diameter equal to the drill bit itself. This standard clamping type guarantees compatibility with the vast majority of commonly used hand and pillar drills. The set thus offers a flexible solution for a wide range of applications, from workshop tasks to on-site installations. The h8 diameter tolerance meets industry standards and helps to produce precise holes.
