TOOL BREAKAGE
C. DEFORMATION OF THE TOOL TIP
Hammering continuously in one position for over 30 seconds will overheat the tool tip. If
this is done repeatedly, the tip will lose temper and mushroom. Overheating wears the
tip faster and can allow the tip to chip.
PREVENTATIVE MEASURES
Move tool position if material is not broken after 30 seconds of hammering. If the
material still resists breaking, a larger hammer may be required.
