Drill bit GEKO G37060 cobalt HSS for metal, 6 mm diameter

Cobalt HSS metal drill bit GEKO G37060, 6 mm diameter, is designed for drilling stainless steel and other hard metals. Manufactured from high-speed steel with a cobalt alloy, this drill bit offers improved heat resistance and wear durability compared with standard HSS bits. It is compatible with hand drills and drill presses and performs best when used with an appropriate cutting fluid. The 6 mm diameter provides a balance between rigidity and cutting speed for general metalworking tasks in workshops and industrial maintenance.

Advantages

The cobalt HSS composition increases red hardness and maintains cutting edge integrity at higher temperatures, reducing premature wear during prolonged drilling in stainless steel and hard alloys. The precision-ground flute geometry facilitates efficient chip evacuation and stable drilling, while the 6 mm shank size ensures compatibility with standard chucks. Using cutting fluid further extends tool life and improves surface finish.

Suitable for (tasks / use cases)

• Drilling stainless steel sheets and components
• Working with hardened or alloyed steels
• General metal fabrication and repair work
• Workshop and industrial maintenance tasks
• Drilling with hand drills and drill presses

Key specifications

• Material: high-speed steel (HSS) with cobalt alloy
• Diameter: 6 mm
• Intended application: stainless steel and hard metals
• Compatible with: hand drills and drill presses
• Flute type: precision-ground for chip evacuation

How to use

Secure the workpiece firmly and select the proper drill speed for the material—lower speeds for stainless and hardened steels. Fit the 6 mm drill bit into the drill chuck and ensure it is properly centered and tightened. Apply a suitable cutting fluid to the drilling area to reduce heat buildup and improve chip removal. Drill with steady pressure, periodically retracting the bit to clear chips if necessary. After drilling, deburr the hole and clean residues from the workpiece and the bit.

Usage recommendations

For best results when drilling stainless steel or other hard metals, use slow to medium spindle speeds, apply a dedicated cutting or cooling fluid, and avoid excessive feed pressure to prevent overheating and premature tool wear.
