Drill bit GEKO HSS cobalt for metal 7 mm G37070

GEKO HSS cobalt drill bit for metal, 7 mm diameter is designed for reliable drilling of steel and other ferrous metals. Made from high-speed steel with added cobalt alloy, the bit provides improved hardness and elevated heat resistance compared with standard HSS tools. Its geometry and material composition make it suitable for both handheld and machine drilling in workshops, maintenance, and fabrication environments.

Advantages

The cobalt-enhanced HSS composition increases wear resistance and maintains cutting performance at higher temperatures, reducing the risk of premature dulling during prolonged or heavy-duty drilling. The 7 mm cutting diameter offers a balance between rigidity and material removal rate, while the fluted geometry ensures efficient chip evacuation and consistent hole quality. The bit’s construction supports repeated use on hardened or abrasive metals where standard HSS bits may fail.

Suitable for

• Drilling steel and other ferrous metals
• Workshop and maintenance drill operations
• Fabrication, metalworking and machinery repair
• Handheld and machine drill applications

Key specifications

• Material: high-speed steel with cobalt alloy
• Diameter: 7 mm
• Tip geometry: ground for metal cutting
• Finish: machined flutes for chip removal
• Recommended coolant use: yes, for prolonged cutting or hard materials

How to use

Secure the workpiece and clamp the drill bit correctly in the chuck. Start drilling at low to moderate speed, applying steady pressure; increase speed gradually within the tool’s recommended range for the material being drilled. Use cutting fluid or coolant when working with thicker, hardened, or heat-sensitive metal to reduce friction and extend tool life. Periodically withdraw the bit to clear chips and avoid clogging the flutes.

Usage recommendations

For best results when drilling steel or other ferrous metals, use appropriate cutting fluid, moderate feed rates, and ensure the drill press or handheld drill is stable. Replace the bit if chipping or excessive wear appears to maintain hole accuracy and safety.
