<p>The tool tip assembly has a fixed large tool tip 30 and a movable telescoping tool tip 14 which has a smaller area pick-up end. The telescoping tool tip 14 is displaceable between fixed stops and the forward stop is defined by an annular bumper 44 projecting rearwardly from the inner surface of the fixed tool tip 30 proximate the forward bore portion. The telescoping tool tip 14 can be quickly and conveniently accessed for repair, inspection or replacement by removing the fixed large tool tip 30, which is preferably made of moulded elastomeric material. <IMAGE></p> |
