IRWIN HSS Pro TiN Coated Drill Bit 11.0mm, 142mm Length
High-performance IRWIN 11.0mm TiN-coated HSS drill bit for metal and alloys. Faster drilling, reduced heat, and long life.
The IRWIN HSS Pro TiN Coated Drill Bit is engineered for professional use in drilling through metal and tougher alloys. Made from high-speed steel (HSS) and coated with Titanium Nitride (TiN), it outperforms conventional HSS bits, allowing 40-60% higher drilling speeds and 10-20% increased feed rates without significantly reducing the drill bit's lifespan.
Key Features:
- 135° Split Point Tip – Ensures precise centring and reduces drilling pressure.
- TiN Coating – Provides exceptional hardness (~80 HRC) and wear resistance, making the drill bit more durable.
- Heat Management – Titanium Nitride’s poor heat conductivity diverts heat into the chips and coolant rather than the drill bit, reducing wear.
- Lower Friction – The TiN coating minimises friction, requiring less drilling power and extending tool life.
This 11.0mm diameter drill bit has an overall length of 142mm and a working length of 94mm, making it a versatile choice for metalworking, industrial applications, and fabrications.
Ideal for professionals seeking high-performance drill bits that maintain longevity under tough conditions.
