## Summary description

HSS M35 cobalt drill bit GEKO, 5.5 mm diameter, designed for drilling metal. Made from high-speed steel with cobalt alloy for increased heat resistance and wear performance. Suitable for use in hand drills and drill presses for stainless steel, alloyed steels and other hard metals where higher cutting speed and durability are required.

## Long description

GEKO HSS M35 cobalt drill bit 5.5 mm (model T03055) is a precision cutting tool designed for drilling into metals where higher wear resistance and heat tolerance are required. Manufactured from high-speed steel with a cobalt alloy, this 5.5 mm diameter bit delivers consistent hole quality and extended tool life when used in handheld drills or drill presses. The geometry and material composition are optimized for cutting harder materials such as stainless steel and alloyed steels while maintaining stable performance at elevated cutting speeds.
Advantages
The HSS M35 cobalt construction provides improved hardness and thermal stability compared to standard HSS bits, reducing wear during prolonged drilling in hard metals. The 5.5 mm diameter offers a balance between rigidity and cutting speed, helping to minimize bit breakage and vibration. The bit’s tip geometry enables efficient chip evacuation and more accurate centring on metal surfaces, yielding cleaner holes and fewer reworks.
Suitable for
 Drilling stainless steel and acid-resistant alloys
 Working with alloyed and high-strength steels
 Use in hand drills and drill presses for metal fabrication
 Maintenance and repair tasks requiring precise metal holes
Key specifications
 Material: high-speed steel with cobalt (M35)
 Diameter: 5.5 mm
 Intended material: metals including stainless and alloyed steels
 Suitable for: handheld drills and drill presses
 Tip design: ground for metal drilling and improved chip evacuation
How to use
Secure the workpiece firmly and mark the drilling position. Use an appropriate pilot point or centre punch for accurate start if necessary. Fit the 5.5 mm GEKO HSS M35 cobalt bit into the drill chuck and tighten securely. Select a suitable rotational speed for metal drilling—moderate to low speeds for stainless and hard alloys—and apply steady, even pressure. Withdraw the bit periodically to clear chips and allow cooling. Use cutting fluid when drilling hard metals to reduce heat buildup and extend bit life.
Usage recommendations
For best results, recommend using cutting lubricant when drilling stainless steel or other hard alloys, maintain moderate spindle speeds, and avoid excessive side loads. Replace the bit when wear or chipping affects hole quality to maintain accuracy and safety.
