The S25 is a hard-hitting, powerful pneumatic rock drill for development-end drilling.
The S25 is a hard-hitting, powerful pneumatic rock drill for development-end drilling. With a larger bore and longer stroke than the S215, it delivers heavier blow energy per stroke, making it suited to any drilling application where the operator can adopt a standing, upright posture — development ends, tunnelling and general heavy production drilling.
Like the rest of the Impco drill range, the S25 runs on standard mine air and water services, mounts on standard air legs and extensions, and uses common drill steels — so it drops straight into an existing conventional drilling fleet. It is manufactured to Impco’s in-house specification with premium materials, and backed by a complete spares programme.
