## Summary description

Cobalt HSS drill bit GEKO model G37115, 11.5 mm diameter, designed for drilling metal. Made from high-speed steel with cobalt content for improved heat resistance and wear life when cutting hardened and stainless steels. Suitable for hand drills and drill presses in metalworking, maintenance and fabrication tasks where precise, durable metal drilling is required.

## Long description

Cobalt HSS drill bit GEKO model G37115 with an 11.5 mm diameter is designed for precise metal drilling. Manufactured from high-speed steel with added cobalt, this drill bit offers improved heat resistance and extended tool life when working with hardened steels and stainless steels. It is intended for use in hand-held drills and drill presses in metalworking, maintenance and fabrication environments where reliable, repeatable holemaking is required.
Advantages
The cobalt alloy composition increases red hardness and wear resistance compared with standard high-speed steel, allowing higher cutting temperatures and longer service life. The ground spiral flutes evacuate chips efficiently, reducing clogging and improving hole quality. Its 11.5 mm diameter provides a precise hole size for fitting standard fasteners or for preparing subsequent machining operations. The bit is compatible with common drill chucks and is suitable for both intermittent and continuous drilling tasks in metal.
Suitable for
 Drilling through mild, alloyed and stainless steels
 Metal fabrication and workshop drilling
 Maintenance and repair tasks requiring durable bits
 Use in hand drills and bench or pillar drill presses
Key specifications
 Diameter: 11.5 mm
 Material: high-speed steel with cobalt
 Application: metal drilling (including hardened and stainless steels)
 Flute type: twisted/spiral flutes for chip removal
 Suitable mounting: standard drill chucks (hand or press)
How to use
Select an appropriate drilling speed and feed for the workpiece material and secure the workpiece firmly before drilling. Use recommended cutting fluid when drilling stainless or hardened steels to reduce heat and extend bit life. Start with a center punch mark to avoid walking, and drill at steady pressure without excessive side forces. Clear chips frequently from the flutes to maintain cutting efficiency and periodically inspect the bit for wear or damage.
Usage recommendations
For best results on stainless and hardened steels, operate at lower speeds with consistent cutting fluid and moderate feed pressure. Replace the bit when wear or loss of cutting performance is observed to avoid oversized holes or increased force on the tool and machine.
