Button bits should be reground when penetrati on rat es drop or if the cemented carbide shows signs of damage
Fixed grinding routines often result in good working practices.
Bits for instance, can be examined and then reground after a specific number of holes, or at the end of the shift. Premature grinding is not necessarily uneconomical since less carbide needs to be ground off. It is better to regrind rather than reducing productivity due to damage.
Correct grinding adds considerably to drill bit service life. But equally important, it also enhances the performance of the entire drilling operation, especially hole straightness.
