Drill bit Bosch 10 mm HSS 2608594070 for metal drilling

Bosch 10 mm HSS drill bit is a high-speed steel bit designed for precise metal drilling and other hard materials. With a 10 mm diameter and HSS construction, this drill bit offers consistent cutting performance, wear resistance and good edge retention for workshop and professional applications. It is compatible with standard chucks on hand drills and drill presses, providing reliable hole quality for fabrication, maintenance and repair tasks.

Advantages

The HSS material delivers elevated hardness and heat resistance compared with carbon-steel bits, reducing dulling during extended drilling in metal. Its 10 mm diameter provides a balance between structural rigidity and versatility for common hole sizes. The bit’s geometry ensures stable drilling with reduced wandering and a clean drilled surface when used at appropriate speeds and with correct lubrication. It is suitable for repeated use in workshop routines thanks to predictable wear behavior and straightforward resharpening when required.

Suitable for

• Drilling holes in mild and alloy steels
• Punching starter holes in stainless and hardened materials (with appropriate technique)
• Using in hand-held drills and bench drill presses
• General maintenance, fabrication, and repair work

Key specifications

• Material: High-speed steel (HSS)
• Diameter: 10 mm
• Point geometry: general-purpose twist point suitable for metal
• Shank: round shank compatible with standard chucks
• Typical applications: metalworking and other hard materials

How to use

Secure the drill bit in the chuck making sure it is centered and tightened. Select an appropriate drilling speed for the material — lower speeds for harder alloys and higher speeds for softer metals — and use steady, moderate feed pressure. Apply cutting fluid or lubricant when drilling metal to reduce heat buildup and improve chip evacuation. After completing the hole, retract the bit while the drill is still turning to clear chips and avoid clogging.

Usage recommendations

For best results, match drilling speed and feed to the workpiece material and use cutting fluid on thicker or harder metals. Inspect the bit periodically for wear and resharpen or replace when the cutting edge becomes rounded to maintain hole quality and reduce heat generation.
