RH 658 5L Sinker Drill

The RH 658 5L (Part No. 8311 0302 77, Shank: 22 x 108 mm) is a genuine Atlas Copco sinker drill. It weighs 24 kg. Small in size, but it drills down to 6 metres, even through hard rock. You can buy it as the original Atlas Copco tool. Or you can choose the RMT 658 — a 100% equivalent aftermarket version, with spares that fit the original, at a lower cost.

Always in stock. This is one of our fastest-moving export products. We keep around 10 units ready at all times, so most orders ship without delay.

Key Features of the RH 658 5L

There's a reason this drill has stayed an industry standard for decades:

• Faster rotation than the RH 572E. The RH 658 5L spins at 215 rpm. The RH 572E spins at 170 rpm. In real drilling, this means rounder holes, better cleaning of drilled material, and more accurate blast patterns in hard rock like granite, quartzite, and basalt.
• Drills 6 metres deep, with power to spare. The RH 572E also reaches 6 metres. But the 658 5L does it with more strength. That makes it the better choice in harder, more abrasive rock, where lighter drills slow down or wear out faster.
• 22 x 108 mm Shank: - It comes with a shank size of 22 x 108 mm (⁷/₈" x 4¼") which is one of the most common and widely available sizes.
• Spares are easy to find, almost everywhere. The RH 658 is one of the most used sinker drills in the world. That means spare parts are stocked in nearly every mining country. Thus, you don't need to carry stock of the tool. And with RMT you wil also get the option to buy 100% equivalent RH 658 aftermarket spare parts at an attractive price and quick delivery.

Why Choose the RH 658 5L?

Think of the RH 572E as the long-distance runner. The RH 658 5L is the power lifter. It's built for tougher rock, harder sites, and jobs where drilling speed and hole quality really matter.

Mining or construction projects which require drilling in hard or abrasive rock — granite, quartzite, iron ore, or hard dolomite — usually pick the 658 5L over lighter drills. Its faster rotation and stronger motor keep the drilling speed up, even where other drills start to slow down.

So why pick the RH 658 5L over other pneumatic drills on the market, not just other Atlas Copco models? A few reasons:

• Perfect weight to play around for longer drilling. At 24 kg, it's still light enough for one operator to carry and reposition through a shift. Many drills with this much drilling power weigh more, and that extra weight adds up in fatigue over a long day.
• It's proven, not experimental. This isn't a new design. It's been the standard sinker drill — known as 'perforadora sinker' across Spanish-speaking mining sites and 'perfuratriz pneumática' in Brazil — on mining sites for decades. When a tool has been tested this widely for this long, you know exactly what you're getting, without the risk of any kind of surprises on-site.
• Spares are everywhere. Because it's used so widely, spare parts are stocked in nearly every mining country. If something wears out, you don't have to wait for weeks for a part to arrive.
• You get to choose your budget. Buy the original Atlas Copco RH 658 5L, or the RMT 658 aftermarket equivalent — same shank, same performance, interchangeable spares, lower cost. Few drills on the market give you that flexibility without compromising on the quality and performance
• It's built for the jobs that matter most. Blast hole drilling, quarry bench drilling, shaft sinking, excavation, road construction — this drill covers the core work most mining and quarry sites need, without needing a different machine for each task.    

Unknown Fact about RH 658 Pneumatic Rock Drill

One of the hidden and lesser-known facts about the RH 658 5L (8311030277) or RMT 658 is that, using a single adapter, it can also be used as a jackleg drill.

The adapter will allow the drill to get attached with the Jackleg / Pusherleg RMT 62S.

And thus, it can be converted to a jackleg drill for horizontal drilling in underground mines.

Where is the Pneumatic Rock Drill RH 658 used?

This drill is used for blast hole drilling, quarry bench drilling, shaft sinking, excavation, and road construction — in hard rock, all over the world. Its two biggest markets today are Peru and Brazil. In Peru, mining teams searching for a perforadora neumática RH658 trust it for daily, heavy-use drilling. In Brazil, it's sold and serviced widely as the perfuratriz pneumática RH 658, a familiar name on quarry and mining sites across the country.
