Armeg 4-22mm Pro-Step Drill

The Armeg EMWSD04-22 Pro-Step Step Drill is designed to produce rapid, clean and accurate holes in trunking, sheet steel and thin metal materials. Manufactured in Sheffield, using a precision production process, it delivers professional results while providing multiple hole sizes from a single drill bit.

Featuring 10 stepped diameters from 4mm to 22mm, the drill offers excellent versatility for installation and fabrication work. Laser-etched diameter markings allow quick size identification and help achieve consistent, repeatable results, while the fully ground body profile produces smooth, round, burr-free holes.

Precision-ground tapered cutting edges enable efficient drilling through metals up to 5mm thick, making the EMWSD04-22 ideal for electrical, mechanical and general metalworking applications.
