RH 571 Pneumatic Rock Drill

At approximately 17.8 kg and 510 mm length, the RH 571 is one of the lightest drills in the RH range. This makes it easier to position and operate for longer periods, especially in confined working areas.

Key Features and Specifications

• Lightweight design — Weighing approximately 17.8 kg, the RH 571 provides easier handling and reduced operator fatigue during extended drilling operations.
• Compact construction — The 510 mm compact body design makes it suitable for confined spaces and difficult working areas.
• Reliable drilling performance — Operates at approximately 39 l/s air consumption with around 2,100 blows per minute for efficient rock penetration.
• Built-in air flushing — Air flows through the drill steel to remove drilling cuttings and reduce the possibility of jamming during operation.
• Standard shank size — Available with 22 x 108 mm (⁷/₈" x 4¼") shank specification.

What Makes the RH 571 Stand Out

The RH 571 combines lightweight construction with reliable hard-rock drilling capability. It uses the same rifle-bar rotation mechanism and air flushing system found in larger RH models while maintaining a lower operating weight.

Although lighter than the RH 658, the RH 571 can achieve similar drilling depth capability of up to 6 metres. The main difference is the hole diameter range, where the RH 571 supports approximately 28 mm to 34 mm compared to the larger RH 658.

RH 571 vs RH 658 Pneumatic Rock Drill

• RH 571 — Lightweight option at approximately 17.8 kg, suitable for confined spaces, smaller diameter holes and applications where operator comfort is important.
• RH 658 — Heavier drill at approximately 24 kg, designed for higher air consumption and larger hole diameter requirements.
• Hole Capacity — RH 571 supports approximately 28–34 mm hole diameter, while RH 658 supports larger hole sizes up to approximately 40 mm.

In simple terms, the RH 658 provides more drilling power and larger hole capacity, while the RH 571 provides better manoeuvrability and lower operator fatigue.

Why Choose the RH 571 Over RH 658

1. Better Manoeuvrability — The lighter design makes it easier to operate in confined spaces and areas where frequent repositioning is required.
2. Lower Air Requirement — Lower air consumption makes it suitable for sites with limited compressor capacity.
3. Operator Comfort — Reduced weight helps decrease fatigue during long drilling shifts.

OEM Availability

RMT supplies the RH 571 in both options — the original Atlas Copco RH 571 and the RMT 571 aftermarket equivalent.

The RMT 571 is manufactured to match the original specifications with interchangeable spare parts. Customers can also select original or aftermarket spare parts according to their requirement.

RMT 571 is also supported with a 6-month replacement warranty against manufacturing defects.

Get the Right Configuration

If you are selecting between RH 571 and RH 658, RMT can help you choose the correct model based on compressor capacity, required hole diameter, drilling conditions and application requirements.
