Precision IRWIN metal drill bit with titanium nitride (TiN) coating for fast, clean, and durable drilling. 135° ground tip for easy centering, industrial spiral for rapid chip removal, and up to 6× longer life compared to standard HSS bits with black oxide finish.
The IRWIN HSS TiN metal drill bit with a 6 mm diameter is designed for precise drilling in metallic materials. A high-quality high-speed steel body with a titanium nitride (TiN) coating withstands high temperatures and friction, delivering stable performance even in demanding applications. The 135° ground tip ensures perfect centering and reduces the required feed pressure.
Thanks to the precision-ground industrial spiral, the bit efficiently evacuates chips and increases work speed. The TiN coating with a hardness of about 80 HRC has a low coefficient of friction, which limits heating and reduces energy consumption. Compared to standard twist HSS drill bits, you can increase RPM by 40–60% and feed by 10–20% without significantly shortening tool life.
- Longer service life: up to 6× compared to standard HSS bits with black oxide finish
- Faster work: optimized geometry and industrially ground spiral
- Greater wear resistance: hard TiN coating ~80 HRC
- Clean and precise holes: 135° tip for easy bite and reduced chatter
- Universal clamping: cylindrical shank for a wide range of chucks
