Why choose it

The TL 3000 coating reduces friction and heat buildup, extending tool life and improving chip evacuation. The 135° split point allows for accurate centring without a centre punch and reduces walking on the workpiece. Ground from solid HSS-G, these bits offer high toughness and wear resistance for demanding drilling applications.

Ideal use cases

• Drilling precise holes in steel and cast iron
• Working with non-ferrous metals such as aluminium and brass
• Creating clean holes in plastics and wood
• General workshop and maintenance tasks

Good to know

The set is supplied in a robust plastic cassette that keeps the bits organised and protected. Each drill bit is manufactured to DIN 338 with h8 tolerance for consistent diameter accuracy.
