Usage
Engineered for drilling tasks in alloyed and unalloyed steels (up to 900 kg/mm² tensile strength), malleable cast iron, sintered iron, silver, aluminum, copper, bronze, and plexiglass. Use with standard rotary drills or drill presses. Always employ a suitable coolant to maximize tool life and cutting efficiency.
FAQ
-
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.
-
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.
-
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.
-
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.
-
Is coolant required during drilling?
- Yes, using a cooling fluid is recommended to maintain performance and extend the bit’s lifespan.
