## Summary description

Cobalt HSS metal drill bit GEKO G37120 with 12 mm diameter. Designed for drilling in hardened steels and other metals where increased heat resistance and wear resistance are required. Suitable for use with hand drills and drill presses in metalworking, repair, and fabrication tasks. Single-piece construction for stability and consistent chip removal.

## Long description

Cobalt HSS metal drill bit GEKO G37120 12 mm is a single-piece high-speed steel drill designed for drilling into hardened steels and a wide range of metal materials. The cobalt alloy in the cutting tip increases red hardness and wear resistance, enabling longer tool life under higher temperatures and more demanding cutting conditions. The 12 mm diameter provides a balance between hole size and rigidity, suitable for standard metalworking operations with hand drills or drill presses.
Advantages
The cobalt HSS composition offers improved heat resistance compared with conventional high-speed steel, which reduces edge wear during prolonged drilling in tough metals. Single-piece construction enhances stability and concentricity, while the optimised flute geometry supports efficient chip evacuation to minimise clogging. The 12 mm diameter and robust point geometry maintain accuracy and straightness when drilling through thin and medium-thickness metal sheets and bars.
Suitable for
 Drilling hardened steel and stainless steel
 General metal fabrication and repair
 Use with hand-held drills and drill presses
 Workshops, maintenance and mechanical assembly tasks
Key specifications
 Material: high-speed steel with cobalt alloy
 Diameter: 12 mm
 Construction: solid one-piece drill bit
 Suitable for: steel, stainless steel and other ferrous metals
 Shank type: straight cylindrical shank for standard chucks
 Tip geometry: split/point geometry for improved centring and reduced walking
How to use
Secure the workpiece and select an appropriate clamping method to prevent movement during drilling. Install the drill bit into the chuck making sure it is centred and tightened. Use cutting fluid or coolant when drilling hardened steels to reduce heat and extend tool life. Start at a low speed to establish the hole, then increase speed within recommended limits for HSS cobalt drills while applying steady axial pressure. Withdraw the drill periodically to clear chips and avoid overheating.
Usage recommendations
For best results, match drill speed and feed to the material: lower speeds for harder steels and higher speeds for softer metals. Regularly apply suitable cutting fluid, ensure secure clamping, and avoid excessive lateral force to prolong drill life and maintain hole accuracy.
