Product Overview

The RMT 658 is a sinker drill designed for vertical drilling in hard rocks. It's built for quarry operations, blast hole drilling, tunnelling, and general construction sites where a compact, handheld pneumatic rock drill is needed.

The RMT 658 is a 100% OEM-equivalent to the RH 658 (8311 0301 86), manufactured to match form, fit, and function so it works as a straightforward replacement without modifying your existing rod, bit, or even the stock of the spare parts of RH 658.

Key Features & Benefits

• Low air consumption relative to output → lower compressor demand and running cost per hole

• H22 integral and extension steel compatibility → drills deeper holes using 22 x 108 mm standard rod which is available world wide.

• Compact, handheld design → easy to manoeuvre in tight quarry faces and tunnel headings

• Simple, field-serviceable design → less downtime for on-site repairs

• Matched OEM shank and rod fitment → no need to change existing spare parts and accessories inventory as it matches 100% with the Atlast Copco original RH 658 (8311030186)

The most amazing feature of the 658 Rock Drill (8311 0301 86) is that, it can also be used as a jackleg drill by using an adapter to adjust and connect it with the pusherleg (Pie de avance).
