IRWIN HSS Pro TiN Coated Drill Bit, 4.0mm x 75mm
IRWIN HSS Pro TiN coated drill bit for metal & alloys. 4.0mm x 75mm, 135° split point tip, reduces heat & wear.
The IRWIN HSS Pro TiN Coated Drill Bit is engineered for precision drilling in metal and tough alloys. Featuring a Titanium Nitride (TiN) coating, this drill bit offers exceptional durability and performance, allowing for 40-60% increased speed and 10-20% higher feed rates compared to standard HSS bits, without compromising bit longevity.
The 135° split point grinding tip ensures perfect centring and reduces drilling pressure, making it easier to start holes accurately. The TiN coating not only enhances the bit's hardness to approximately 80 HRC but also acts as a poor heat conductor, directing heat into the chips and coolant rather than the bit itself. This results in less power consumption and reduced heat generation during use.
Key Features:
- Material: High-quality HSS steel with 2.5µ TiN coating
- Drilling Tip: 135° split point for precise centring
- Heat Management: Low friction coefficient minimises heat build-up
- Size: 4.0mm diameter x 75mm overall length
- Shank Length: 43mm (working length)
Ideal for professionals and serious DIY enthusiasts, the IRWIN HSS Pro TiN Coated Drill Bit delivers superior performance and longevity in demanding drilling applications.
