I can only find unsubstantiated forum opinions on the net. Any idea what the correct spec for an electric die grinder with a range 3000-30000 RPM is? Would grease designed for petrol strimmer gear heads be ok - I think they run about 10000-12000rpm? Would it be classed as high speed/low-load or high speed/high load or high speed/high temperature grease that's needed? It's 750w. It takes 6mm shaft diameter bits. The heads on mine are up to 15mm diameter.
