Abstract
A stabiliser tool for connection in a drill string having a fluted stabilising portion comprising a body part (16) integral with the shank (10) of the tool and a leading end sleeve part or cap (18) removably secured to the shank. The cap (18) can readily by replaced when worn. The tool may be suppled as a set including different interchangeable caps having for example, spiral flutes (22) for normal stabilising operation, or straight flutes to enable the tool to be used as a reamer when drilling rough and abrasive rock formations.
