REVERSE CIRCULATION TOOLS
Select RC hammers together with the rig, rods and air supply. Browse product photographs by model. For an enquiry, specify the existing model, target hole diameter, connections and equipment configuration.
Multiple models for different hole sizes
An RC hammer uses compressed air to drive an internal piston that impacts the bit while the rig rotates it to break rock. RC543, RC052, RC040 and PR54 differ in diameter, hole range and air demand; their model numbers are not performance rankings.
The hammer is part of the RC tooling system, so its rod connection and air requirements should be checked together. For replacements, the current model, markings and connection photos help establish whether a complete hammer or an individual component is required.
Order a complete hammer or replacement parts for the model in use. Specify RC543, RC052, RC040 or PR54, then list the required part names and quantities. Confirm the exact PR54 dimensions and configuration with the team.
