DEWALT DW801 850Watt 100mm Heavy Duty Small Angle Grinder
This model 801 is 850W (and 810 is 750W) so choose 850W for heavy use. The price difference is negligible. Unlike other brands Dewalt parts I am told are easy to get and less expensive. Angle grinders are actually meant for cornering, rounding applications but in India I see it is used for all applications like wall cutting, granite cutting etc.
