FAQ

1. What materials can this drill bit handle?

   • It is suitable for alloyed/unalloyed steel, cast iron, non-ferrous metals like silver, copper, aluminum, as well as bronze and plexiglass.

2. What is the tip angle and why is it important?

   • The tip is ground to 135° with a cross-point, ensuring accurate centering and reduced wandering during drilling.

3. Does the titanium coating wear off with use?

   • The titanium nitride coating increases surface hardness and tool life but may gradually wear with extended use, especially without coolant.

4. Is this drill bit suitable for handheld drills?

   • Yes, as long as the drill can accommodate the 11 mm shank and the application allows for controlled feed and stable drilling.

5. Is coolant required during drilling?

   • Yes, using a cooling fluid is recommended to maintain performance and extend the bit’s lifespan.
