Designed for speed, precision and versatility, the Irwin Unibit Step Drill Bit 9 Hole Sizes; 4.0 - 12mm from ITS is a professional solution for drilling multiple hole sizes with a single tool.

Ideal for electricians, HVAC installers and metalworkers, this step drill eliminates the need to switch between different drill bits, making it a highly efficient choice for repetitive and on-site work.

At the core of its design is the ability to drill nine different hole sizes ranging from 4mm to 12mm, allowing users to create clean, accurate holes in thin materials such as sheet metal, plastic and light steel. This multi-step functionality significantly reduces setup time and improves workflow, especially when working across varying hole sizes in a single task.

The single-flute cutting design ensures smooth drilling performance and excellent control, helping to produce perfectly round holes with minimal vibration. This design also improves chip removal and reduces heat build-up, resulting in cleaner cuts and extended tool life.

A self-centring tip prevents the bit from wandering at the start of drilling, eliminating the need for pre-drilling or centre punching. This not only speeds up the process but also improves accuracy, particularly on smooth surfaces.

Manufactured from industrial-grade M7 high-speed steel, the bit is built for durability and long-term performance in demanding applications. The flat shank design prevents slipping in the chuck, ensuring consistent power transfer and safer operation during use.

Laser-etched size markings along the flute provide clear visibility of each step, allowing users to quickly identify hole sizes and maintain accuracy throughout the job.

Compact, efficient and highly versatile, the IRWIN step drill bit is an essential addition to any professional toolkit, delivering fast, accurate results while reducing the need for multiple tools.
