My Rating 9/10
This porter cable 20v grinder has to be the top budget grinder on the market If you have similar batteries on other tools such as black and decker and don,t want to spend much its a no brainer . Power and light weight are probably the most salient features in this line of 20-volt tools. Porter-Cable is to be commended on their design. Now that the 4 amp-hour batteries are available, they are even more attractive. It has impressive power and run time for its price.
