Abstract

A drive mechanism for a hammer drill comprises a hollow piston 558 having a cylindrical bearing that receives a crank pin in order to cause the hollow piston 558 to reciprocate inside a spindle, Figure 25, 548. A plurality of longitudinal ridges 559 are formed on the outer surface of the hollow piston 558 to reduce the surface area of contact between the hollow piston 558 and the spindle, Figure 25, 548, and a plurality of grooves 561 are formed in the gaps between the ridges. The grooves 561 retain lubricant 558 in order to reduce frictional contact between the hollow piston 558 and the spindle Figure 25, 548.
