## Summary description

GEKO T03085 is an HSS M35 cobalt drill bit for metal with an 8.5 mm diameter. Designed for drilling steel and other ferrous materials, the M35 cobalt alloy provides increased heat resistance and wear performance compared with standard HSS. Suitable for use in hand drills and drill presses for metalworking, maintenance, and fabrication tasks.

## Long description

GEKO T03085 HSS M35 Cobalt drill bit with an 8.5 mm diameter is engineered for reliable drilling in steel and other ferrous metals. Made from high-speed steel with 5% cobalt (M35), this bit offers improved heat resistance and edge retention compared with standard HSS, enabling longer service life under demanding metalworking conditions. The geometry and cutting angles are optimized for metal drilling, providing consistent hole quality when used in both hand drills and drill presses.
Advantages
The M35 cobalt alloy construction increases hardness at elevated temperatures and improves wear resistance, reducing the frequency of bit changes during continuous work. Its precise tip geometry aids in accurate centring and reduces walking on workpiece surfaces. Compatibility with common drilling equipment makes it a practical choice for maintenance, fabrication and industrial repair tasks where durability and hole consistency are important.
Suitable for
Drilling mild and alloy steels
Maintenance and repair of metal components
Fabrication and assembly in workshops
Use in hand drills and drill presses
Key specifications
Material: High-speed steel with cobalt (M35)
Diameter: 8.5 mm
Intended use: Ferrous metals and steel
Suitable tools: Hand drills and drill presses
Drill tip: Split/standard metal-drilling geometry for reduced walking and improved centring
How to use
Secure the workpiece firmly and mark the drilling point before starting. Select appropriate drill speed for the material—moderate to low speeds for harder steels—and apply steady, even pressure without forcing the bit. Use cutting fluid or coolant when drilling thicker sections or tougher alloys to reduce heat build-up and prolong bit life. Retract periodically to clear chips and maintain cutting efficiency.
Usage recommendations
For best results, start with a smaller pilot hole when drilling large or tough workpieces, use adequate clamping and appropriate cutting fluid, and replace the bit when wear degrades hole quality. Store the bit in a dry toolbox to prevent corrosion.
