Summary: Hitachi's G12SR3 grinder can be smart purchase, if you know what you are looking for. The team at Hitachi has designed a tool that performs well in light to medium duty applications. If you plan on using your grinder for less than 10 minutes an hour, the G12SR3 will serve you well.
Pros: Small and inexpensive, good power switch, large, metal spindle lock button, aggressive forward leaning handle position, 360 degree spark shield
Cons: light duty only, tool will over-heat under heavy load, loud, like every grinder
Summary: The angle grinder really seemed to be a one-stop shop for many applications throughout many of our in-house test projects – which is why it’s one of our “mandatory” handyman tool suggestions for those looking to equip themselves for multiple projects around the house.
