These discs are rated for 10,200 the grinder is 11,000rpm so I run it on number 5 on the speed control. I have my eye on a nice branded 5" grinder which is 10,000rpm and 1400W too.Excellent, may have to copy that. I could occasionally use the extra reach of a 150. My cordless is below the rated 10k rpm of a 150mm disc too.
