## Summary description

Cobalt HSS drill bit GEKO G37125, 12.5 mm diameter, designed for drilling metal. Made from high-speed steel with cobalt alloy for increased heat resistance and wear performance when working with stainless steel and hard metals. Suitable for drilling tasks in workshops, metal fabrication, maintenance and repairs requiring precise holes in ferrous materials.

## Long description

GEKO G37125 cobalt HSS drill bit, 12.5 mm diameter, is designed for drilling holes in ferrous and other hard metals. Manufactured from high-speed steel with an added cobalt alloy, this drill bit offers improved heat resistance and wear performance compared with standard HSS bits, enabling more consistent cutting in stainless steel and other tough materials. The 12.5 mm cutting diameter and standard twist geometry provide a balance of rigidity and cutting efficiency for workshop, fabrication and maintenance tasks.
Advantages
The cobalt-enhanced HSS material increases hardness at elevated temperatures, reducing the risk of cutting edge softening during prolonged or heavy-duty drilling. The bit’s ground flute geometry promotes effective chip evacuation and stable cutting, while the solid construction ensures precise hole size and alignment. These features together extend tool life and maintain drilling performance when working with stainless steel, cast iron and other hard alloys.
Suitable for
 Drilling precise holes in stainless steel and other hard ferrous metals
 Metal fabrication, assembly and maintenance tasks
 Workshop and industrial repair operations requiring durable drill bits
 Punch-through and through-hole drilling where heat resistance is required
Key specifications
 Diameter: 12.5 mm
 Material: High-speed steel (HSS) with cobalt alloy
 Point angle: standard for metal drilling (ground tip)
 Geometry: twisted flute for chip removal
 Intended material: ferrous metals, stainless steel and other hard alloys
How to use
Secure the workpiece and mark the drilling location. Use a center punch for precise start positions in hard metals. Mount the drill bit in a suitable drill or drill press with a correct chuck tightening torque to avoid slippage. Begin at a moderate speed and apply steady feed pressure; for stainless steel and hard alloys, reduce speed compared with soft metals to limit heat buildup. Use cutting fluid or lubricant appropriate for metal drilling to improve cooling and chip evacuation. Withdraw the bit periodically to clear chips if drilling deep holes.
Usage recommendations
For best lifetime and hole quality, use coolant when drilling stainless steel or high-alloy steels, maintain appropriate spindle speed for the 12.5 mm diameter, and replace the bit when wear or chipping reduces cutting efficiency.
