RMT 12D - Pneumatic Rock Drill

Its compact 565 mm length and D-shaped handle make it easy to control with one or two hands in tight working positions; this is one of the biggest USP of this tool — jobs that need accuracy over raw depth.

The RMT 12D Rock Drill isn't a deep-hole production drill. It's built for shallow, precise work: plug holes, anchor and wedge holes, horizontal drilling, and drilling into concrete up to about a metre deep.

Its 22 l/s air consumption is modest compared to heavier sinker drills, so it's also a sensible choice where compressor capacity on site is limited.

Where Is RMT 12D Used?

The RMT 12D is mainly used for plug hole drilling and anchor and wedge hole drilling — jobs where you're placing a hole for a fastening or a splitting wedge rather than drilling a full blast hole. It's also used for horizontal drilling and general concrete drilling up to a metre in depth, which makes it a practical tool on construction sites and quarry benches alike, not just underground.

Because of its light weight, operators use it in places that are awkward to reach — overhead positions, confined recesses, and spots where a heavier drill would be exhausting to hold steady. Its built-in air flushing keeps the hole clear of cuttings as it drills, which matters for hole quality even at this smaller scale.

Why Choose the RMT 12D?

If your job needs a drill which you can hold and reposition constantly through a shift, especially where you need to carry the weight of the tool for horizontal or vertical upward drilling and the weight of the drill matters more than raw power — and this is where the RMT 12D fits.

Its lightweight build makes it comfortable for the operator to manoeuvre in awkward positions than a full-size sinker drill, without compromising on the accuracy needed for plug and anchor holes.
