Bosch HSS-G kierrepora 10,5 mm DIN 338 2608577299

Drilling precise holes in metal demands a bit that stays sharp, cuts cleanly, and resists heat. The Bosch HSS-G Twist Drill Bit 10.5 mm meets that challenge with a ground high-speed steel construction and a 118° point angle, making it a reliable choice for workshops and job sites. Its DIN 338 compliance ensures consistent geometry and performance across a wide range of metals and plastics.

Who is it for

This drill bit is built for metalworkers, maintenance technicians, and serious DIYers who need clean, accurate holes in alloyed and non-alloyed steel, cast iron, non-ferrous metals, and plastics. It fits standard drill chucks on both corded and cordless drills, so it slots into almost any existing toolkit.

Main features

• Ground HSS-G high-speed steel for long life and heat resistance.
• 10.5 mm diameter with 87 mm working length for deep-hole capability.
• DIN 338 standard ensures precise concentricity and flute geometry.
• 118° point angle for fast cutting and reduced walking on metal surfaces.
• Bright finish reduces friction and improves chip evacuation.
• Cylindrical shank fits all standard drill chucks.

Tips

Use a centre punch to mark the hole position before drilling to prevent the bit from wandering. Apply cutting fluid when drilling steel to extend bit life and improve finish. For best results, start at a low speed and increase gradually as the bit bites into the material.
