Product
The Bosch 12mm metal drill bit is engineered for precise drilling in both alloyed and non-alloyed steel, cast iron, non-ferrous metals, and hard plastics. Ideal for workshop, industrial, and maintenance applications.
Specifications
- Precision-ground HSS-G (high-speed steel, ground) construction with a 12mm diameter and a total length of 151mm
- Built to DIN 338 standards for reliable performance and durability
- Features a self-centering 135° split-point tip for improved accuracy and reduced walking; enables up to 40% faster drilling with 50% less feed pressure compared to standard HSS bits
- Suitable for use on materials with tensile strengths up to 900 N/mm²
- Bosch quality assurance and compatibility with most standard drill chucks
Usage
This drill bit is designed for direct use in hand-held power drills or drill presses. The split-point tip eliminates the need for pilot holes up to 10mm diameter, ensuring accurate starts and clean holes. Always apply suitable cutting oil to optimize lifespan and maintain performance during metal drilling.
