## Long description

GEKO T03040 is a 4 mm HSS M35 twist drill bit engineered for drilling metal. Manufactured from cobalt-alloy high-speed steel (M35), this drill bit delivers greater wear resistance and improved heat tolerance compared with standard HSS, making it suitable for drilling steels and other ferrous materials. The 4 mm diameter and standardized twist geometry provide precise centering and efficient chip evacuation when used with hand drills or drill presses in metalworking environments.
Advantages
The cobalt-alloy M35 composition increases hardness and maintains cutting performance at elevated temperatures, extending tool life during continuous or demanding drilling. The twist-flute design promotes reliable chip removal and reduces binding in through-holes. The 4 mm size offers a balance of rigidity and cutting speed for common metal fabrication and maintenance tasks.
Suitable for
 Drilling mild and alloy steels
 Metal fabrication and assembly
 Maintenance and repair work on machinery and structures
 Use with hand drills and drill presses
Key specifications
 Material: Cobalt-alloy high-speed steel (M35)
 Type: Twist drill bit
 Diameter: 4 mm
 Suitable materials: Steel and other ferrous metals
 Flute form: Two-flute spiral for chip evacuation
 Intended use: Metal drilling with hand drills and drill presses
How to use
Secure the drill bit in the chuck of a hand drill or drill press, ensuring it is centered and tightened. Mark the drilling position on the workpiece and, if needed, use a center punch to prevent wandering. Start at low speed to establish the hole, then increase speed appropriate to the workpiece material and drill diameter. Apply steady pressure and allow the bit to cut; avoid excessive force that can cause overheating. For deeper holes, retract periodically to clear chips and reduce heat buildup. Use cutting fluid or lubricant suitable for metal drilling to improve cutting efficiency and prolong tool life.
Usage recommendations
Use appropriate personal protective equipment, clamp the workpiece securely, and select drill speeds and cutting fluids based on the specific steel or ferrous material being drilled. Replace the bit when wear or chipping degrades performance.
