Why choose it

The split point geometry centres the bit on contact, reducing the need for centre punching and improving hole position accuracy. Fully ground flutes ensure consistent chip evacuation and a bright finish that resists corrosion in normal workshop conditions.

Ideal use cases

• Drilling steel and cast iron components in metalworking
• Maintenance and repair tasks in industrial settings
• Creating holes in non-ferrous metals and plastics
• Woodworking where a clean, precise hole is required

Good to know

This drill bit is manufactured to DIN 338, the standard for short series twist drills with cylindrical shank, ensuring compatibility with standard drill chucks. For best results, use appropriate cutting speed and feed for the material being drilled.
