Grind! That's our sharpest
advice for effective drilling.
Well-timed grinding is key to rock drilling productivity.
The key is tracking your penetration rate. When it goes down,
it's time to regrind. Typically, you can drill until the wear
flat ratio (width of wear flat area / the button diameter) is
40–50 %. And when you regrind, make sure that you keep a
wear flat area of about 10 % – there's no point in grinding away
