This grinder works great, but the trigger switch has a design flaw ...
5 February 2015
Summary: A word of caution. I'm the tool repair guy at a steel fabrication shop. This grinder works great, but the trigger switch has a design flaw that makes it break easily. The cost of the replacement part is more than half the cost of a new tool! Come on, $65 - 70 for a switch?
Summary: I bought one of these a couple years ago when I was rebuilding an old steel trailer I bought . I looked at both Makita and Milwaukee tools, but this Hitachi was similar and considerably less expensive. I've gone through 2 or 3 6 inch wire rope cup style brushes with it and it really works hard.
Summary: Bought this to put in diamond blade to cut back stone around four doors for replacement, was kinda scary how much power this thing has! Also love the three holes for handle, made it easier to do horizontal cuts over doors. I just need to cut a tad deeper, wonder if a 9' blade will fit on it?
Summary: I use this with a concrete grinder to smooth old concrete floors. A grinder cover with a dust port would be a great addition, along with an extra handle or a round over the top handle. This machine can handle just about anything. It's a good thing it rides on the floor because it is pretty heavy.
Summary: Very pleased. Used it to remove loose paint from an old wood porch prior to priming and repainting. Works well with a 7" flap sanding wheel that attached directly to grinder. Weight of grinder is perfect. No need to press grinder down hard to get it to cut.
