PROPER USE & CARE OF TOOL BITS

In its most extreme forms, the combination of surface damage and severe bending can quickly break even the best working steels.

The illustrations below show examples of severe stress breaks.

As the next illustration shows, fatigue failures take many forms, but they all exhibit similar features. Generally, the broken surface is brittle and has a “lip” like that in the bending failure, even though, in some cases, the lip has been broken.

Similar failures can also occur when the steel is used with extreme down pressure, and the steel repeated- ly slips off the work at an angle, or the material, itself moves from under the working steel.

Figure 19. Mushrooming

If the overheated steel is suddenly cooled by being dipped in standing water, for example, the metal will harden and become brittle. These are some examples of failure caused by temper changes occurring on the job.
