Use RYOBI Step Drill Bits to drill holes or expand existing ones to precise diameters. They’re suitable for DIY metalwork and craft projects. This Set features 1 x 5 Step Drill Bit (4mm-12mm) and 2 x 10 Step Drill Bits (3mm-12mm and 4mm-22mm).

These Step Drill Bits can be used on metal and plastic. Each one produces multiple hole sizes, which makes it easy to pre-drill materials for pipes, tubes, bolts and screws.

Highly visible, laser-etched markings provide a simple guide to drill correct hole sizes.
The dual straight flute design enhances precision.

These Step Drill Bits are coated with TiN (Titanium Nitride) to reduce heat build-up and friction, maximising bit life.

A ¼” hex shank ensures compatibility with both impact drivers and drill drivers.
