Drill bit MILWAUKEE HSS-G CO Ø10.0 mm — high-speed steel, cobalt tip

MILWAUKEE HSS-G CO Ø10.0 mm is a 10 mm high-speed steel drill bit with a cobalt-enhanced cutting tip designed for drilling in steel and other hard metals. The bit combines HSS-G geometry and cobalt alloy at the cutting edge to increase heat resistance and maintain cutting performance during intensive metalworking. It is intended for use in hand-held drills and drill presses for tasks that require precise hole making in durable materials.

Advantages

The HSS-G geometry provides sustained cutting efficiency and chip removal, while the cobalt-enriched tip improves wear resistance and performance at elevated temperatures. This combination reduces the frequency of tool changes and supports longer continuous operation in workshop or industrial environments. The Ø10.0 mm diameter delivers a standard hole size for common fastening and assembly tasks in metalworking.

Suitable for

• Drilling through mild and hardened steel
• Creating holes in stainless steel and other hard metals
• Workshop, maintenance and industrial metal fabrication
• Use with hand drills and drill presses

Key specifications

• Material: high-speed steel (HSS) with cobalt-enhanced cutting tip
• Diameter: 10.0 mm
• Intended material: steel and other hard metals, including stainless steel
• Geometry: HSS-G (ground flute) for efficient chip evacuation
• Typical applications: metal drilling, assembly holes, maintenance tasks

How to use

Secure the workpiece and select appropriate clamping to prevent movement. Fit the Ø10.0 mm drill bit into the drill chuck and tighten firmly. Use steady feed and moderate drill speeds suitable for metalworking; increase coolant or cutting fluid supply when drilling thicker or stainless materials to reduce heat buildup. Withdraw the bit periodically to clear chips and allow cooling during extended drilling operations.

Usage recommendations

To extend tool life, use cutting fluid when drilling stainless or high-alloy steels, apply progressive feed rates rather than excessive pressure, and match drill speed to the material hardness. Inspect the cutting edge before use and replace the bit when wear compromises hole quality.
