Mission DTH Button Bit

Rock Bit Care

Button

The total life or distance that a rock bit will drill depends on many factors. Of these,

rock bit reconditioning can be the major factor both in the cost and performance of

any rock bit, button or rooftop insert.

Button bits should be reconditioned when the body wears away faster than the button wears, causing it to protrude excessively. This will prevent the button from pinching or shearing off. This frequently happens in softer abrasive ground.
