Grinding Pins

Through years of experience and refinement Pilot is able to offer regrinding tools which allow a button bit to be returned to profitable use as quickly as possible.

As a button develops wear flats the performance of the bit will suffer and as a result, addition feed force will be required to maintain your desired penetration rates. To maintain a “close-to-new” performance face buttons need to be re-profiled when they have developed a wear flat width of 30% of the button diameter. Gauge buttons can also benefit from regrinding as part of the refurbishment process.

Buttons should also be reground if a “snakeskin effect” is noticed, this can rapidly progress to cracks and breakdown of the buttons.
