A:
There are many factors that affect the life of a grinding head. The size of a head and amount of diamond surface. A 1" bit will last longer than a 1/4" bit just because it has more usable diamond surface. Proper lubrication is critical to bit life. Failure to keep the bit wet with coolant while grinding will cause premature wear and reduce its grinding ability. Using excessive pressure or forcing material into the bit instead of allowing the diamond to do the work will cause the bit to wear more quickly. Use all available sections on the bit. There are four bands, slightly larger than 1/8", of usable diamond. By moving the bit up or down on the motor shaft you expose fresh diamond. Fully use each section. Many people move the bit before completely using up that section. When you are really having to push hard against the bit to make it gring then it is time to move the bit.
Use clean coolant and keep the reservoir clean!
