## Summary description

Cobalt HSS drill bit for metal by GEKO, diameter 5.5 mm. Made from high-speed steel with cobalt alloy for increased hardness and heat resistance, suitable for drilling stainless steel, hardened steels and other metals. Designed for use with hand drills and drill presses in workshop and industrial applications where durability and wear resistance are required.

## Long description

GEKO Cobalt HSS Drill Bit for Metal, 5.5 mm diameter, is a cutting tool designed for drilling through a variety of ferrous and non-ferrous metals. Manufactured from high-speed steel (HSS) with a cobalt alloy, the bit offers improved hardness and elevated heat resistance compared with standard HSS bits. Its geometry and material make it suitable for workshop and industrial use with hand drills and drill presses where consistent performance and extended tool life are required.
Advantages
The cobalt alloyed HSS construction increases hot hardness and wear resistance, reducing flank wear during prolonged drilling in hard materials. The 5.5 mm diameter provides a balance between rigidity and cutting speed for common metalworking holes. The bit’s tip geometry is optimized for centering and initial penetration, minimizing walking when starting holes on finished surfaces. Overall, the design supports repeatable hole quality and longer intervals between tool changes.
Suitable for
 Drilling stainless steel and alloyed steels
 Working with hardened steels and heat-treated components
 General metal fabrication and repair tasks
 Use in hand drills and drill presses in workshops and industrial settings
Key specifications
 Material: high-speed steel with cobalt alloy
 Diameter: 5.5 mm
 Intended use: metal drilling (including stainless and hardened steels)
 Shank type: straight round shank compatible with standard drill chucks
 Suitable operating methods: drilling with hand-held drills and bench/top drill presses
How to use
Secure the workpiece firmly in a vise or with clamps to prevent movement. Select appropriate cutting speed and feed for the material being drilled—lower speeds are recommended for stainless and hardened steels to reduce heat build-up. Use a center punch to mark the drilling point to prevent wandering. Fit the 5.5 mm GEKO cobalt HSS bit into a properly tightened drill chuck. Apply steady, moderate pressure and allow the bit to cut without excessive force. Periodically withdraw the bit to clear chips and, where appropriate, use cutting fluid or coolant to prolong tool life and improve hole quality.
Usage recommendations
For best results when drilling stainless or hardened steels, use cutting fluid, maintain lower spindle speeds, and avoid excessive feed force. Inspect the bit for wear and replace when geometry is rounded or cutting performance declines to avoid workpiece damage.
