Description

Step Drill Bit Designed for Fast, Accurate Multi-Size Drilling

Built for electricians and contractors who need speed and precision on site, this step drill bit delivers smooth, controlled cutting across a wide range of materials. Manufactured from HSS M2 steel with a CBN polished finish, it’s engineered to reduce friction and improve drilling efficiency, helping you get through jobs faster with less wear on your tools.

With 13 stepped sizes from 5mm up to 35mm, this bit replaces multiple drill bits in your kit—perfect for quick adjustments when working on panels, enclosures, and general installation tasks where accuracy matters.

Trade-Grade Durability for Reliable Jobsite Performance

When you’re working under pressure, tool reliability matters. This step drill bit is constructed from high-quality HSS M2 steel, designed to handle repeated use across common trade materials including plastic, fibreglass, mild steel, copper, and aluminium.

The CBN polished finish supports cleaner cutting action, helping reduce binding and improving consistency through each step. For licensed electricians and contractors, that means fewer interruptions, fewer tool changes, and more predictable results on every install—especially on commercial and residential fit-outs where deadlines are tight.

Practical Multi-Size Convenience for Faster Electrical Installations

Designed with efficiency in mind, the 13-step size range (5, 7.5, 10, 13, 16, 19, 21, 23, 26, 29, 31, 33, 35mm) gives you multiple hole sizes in a single tool. That means less time swapping bits and more time getting the job done.

Ideal for switchboards, control panels, cable entry points, and general electrical installation work, this step drill bit helps streamline on-site workflows—especially for contractors managing multiple jobs at once. A practical addition to any electrician’s toolkit where speed, accuracy, and space-saving tool storage matter.
