Irwin HSS TCT Drill Bit

This 3.5mm Irwin HSS TCT drill bit is engineered to deliver outstanding performance when drilling hardened materials that require a slightly larger hole size. Combining high-speed steel with a tungsten carbide tip, it offers exceptional durability and precision, making it the ideal choice for demanding tasks in metal, stainless steel, and other tough substrates where standard bits quickly dull or fail.

- Tungsten carbide tip provides superior hardness and long-lasting edge retention when drilling through hardened steel and alloys

- High-speed steel body ensures flexibility and strength, reducing the risk of breakage during heavy-duty use

- 3.5mm diameter is perfectly suited for applications needing a precise, slightly larger hole in tough materials

- Precision-ground cutting edges deliver clean, accurate holes with minimal burr formation

- 135-degree split point design eliminates walking and enables self-starting for effortless, accurate drilling

- Optimised flute geometry promotes efficient swarf removal, reducing heat buildup and extending bit life

- Suitable for use in corded and cordless drills, compatible with a wide range of professional and DIY tools

Whether you are a tradesperson or a serious DIYer, this Irwin HSS TCT drill bit delivers the reliability and cutting performance you need for hard materials.
