Twist drill bit Bosch Metal drill bit HSS-G DIN 338

The Bosch Metal drill bit HSS-G DIN 338 is a high-speed steel twist drill bit with a 2 mm diameter designed for precision drilling in a wide range of metals and some hard plastics. The precision-ground HSS-G geometry and self-centring split point ensure accurate, clean holes while reducing feed pressure and improving drilling speed. This single-piece pack is suitable for professional and DIY use where reliable metal drilling is required.

Advantages

Precision-ground HSS-G flute profile delivers up to 40% faster drilling than standard-ground HSS bits and can reduce feed pressure by up to 50%. The self-centring split point eliminates the need for pre-punching or pilot drilling up to 10 mm diameter, improving accuracy and saving time. Available in Topline quality for the highest demands and in standard professional quality for general metalworking tasks.

Suitable for

• Alloyed and non-alloyed steels with tensile strength up to 900 N/mm²
• Cast steel, cast iron, malleable cast iron and sintered iron
• Non-ferrous metals (e.g., aluminium, copper)
• Hard plastics

How to use

Secure the workpiece and select an appropriate speed for HSS drills and the material being drilled. Clamp the 2 mm Bosch HSS-G drill bit in the chuck, align the self-centring split point with the intended hole position and begin drilling with steady pressure. For holes up to 10 mm diameter, pre-punching or pilot drilling is not required. Use cutting fluid when drilling tougher materials to extend tool life and maintain hole quality.

Recommendations

Use appropriate personal protective equipment (safety glasses, gloves) and cooling lubricant for prolonged drilling. Choose the Topline quality variant for the highest performance demands; the standard variant is suitable for general professional applications.
