Armeg 16-25mm Pro-Step Drill

The Armeg ESD16-25 Pro-Step Step Drill is designed for producing precise, professional-quality holes in sheet steel and trunking. Ideal for installation work, it combines multiple hole sizes in a single tool, helping to reduce tool changes and improve efficiency on site.

The drill bit features stepped diameters ranging from 16mm to 25mm, with laser-etched markings for quick and accurate size selection. Its fully ground body profile produces smooth, burr-free holes, while the precision-ground tapered cutting edges deliver clean cutting performance.

Designed for drilling materials up to 3.5mm thick, the ESD16-25 provides a practical solution for creating larger diameter holes in metal applications.
