Material and durability of BOSCH drill bits
These drill bits are made from high-speed steel (HSS) alloyed with 5% cobalt. This combination significantly increases heat and wear resistance, which is crucial when working with tough materials like stainless steel. As a result, the drill bits retain their long lifespan even during demanding tasks.
Designed for precision and efficiency
The design of these drill bits ensures maximum precision. The split point bites into the material immediately on contact, preventing the bit from wandering and making it easy to start drilling. Two type N spiral flutes guarantee quick chip clearance from the hole, reducing friction, preventing overheating, and increasing overall efficiency.
