The type of work– Reinforced concrete is more detrimental to a chisel than concrete without rebar, the twisting action caused by the flat edge of the chisel against the steel stresses the tool, bushings and retainers.

The type of rock– An abrasive rock will wear the tool faster that a less abrasive material, different types of rock turn to powder under the tool,
Thus cushioning the impact, causing the tool to overheat and mushroom.

Blank-firinganother no-no! Blank firing causes the tool to chip on top and in the retainer area-these chips will enhance the wear and tear on the tool, retainers, bushings and piston.

Proper lubrication at all times– Shortage of lubrication increases the temperature in the bushings and tool shank and will eventually cause deterioration of these components.
