heavy duty angle grinder Grinders Sanders etc I
On a little grinder, thats maybe not a big deal. On a 9 handheld grinder, thatd give me a pucker factor of 9.3 Its also got vibration reducers in both grips. That makes a big difference to the fatigue. I specifically chose a 9 grinder because the RPMs are lower than the smaller ones, however they all have the same size spindle.
