IRWIN® HSS Pro TiN Coated Drill Bits (2 Pack) 1.5mm × 40mm
High-performance IRWIN® TiN-coated HSS drill bits (1.5mm × 40mm) for precision metal and alloy drilling.
The IRWIN® HSS Pro TiN Coated Drill Bits are engineered for precision drilling in metal and tough alloys. These high-performance drill bits offer significant advantages over standard HSS bits, allowing for increased drilling speeds by 40-60% and feed rates by 10-20% without compromising tool life.
A key feature of these bits is the Titanium Nitride (TiN) coating, which provides exceptional wear resistance with a hardness of approximately 80 HRC. The TiN coating also acts as a thermal barrier, diverting heat into the chips and coolant rather than the drill bit, reducing heat buildup and extending tool life. Additionally, the low coefficient of friction of TiN results in lower power consumption and reduced heat generation during drilling.
The 135° split point grinding tip ensures precise centring and minimises drilling pressure, while the high-quality HSS steel construction delivers durability and long-lasting performance. These bits are perfect for professional and DIY applications where precision and efficiency are paramount.
