Customer Reviews

4-1/2 in.7.5-Amp Small Angle Grinder is rated 5.0 out of 5 by 2.
Rated 5 out of 5 by from Great Grinder I purchased this grinder over 2 years ago with a package of 2 grinders and have used the heck out of them. They work really well on everything I've thrown at them. I'm a general contractor and a welder so I've used these to cut concrete, granite stucco, steel, sand wood, strip paint and many other things. The only issue I have with the grinder is the housing broke not too long after I bought it on both grinders where the vents are near the cord. They still work and I just put some super glue and electrical tape around the end and it has held up. other than that they are good grinders lasting way longer than other manufacturer ones I had.

Rated 5 out of 5 by from LIke a lightsaber On a recent bathroom remodel I needed to fit 12x24 porcelain at right angles to a very irregular (imagine contours like a cobblestone street) adobe brick wall. This was in a high-end, architectural home, and the requirement was that the grout line between tile and brick was 1/8 inch. After making a template that matched the wall exactly, then marking the template edge line onto the tile, I needed to cut the line without chipping the tile edge. With this grinder and a Bosch diamond blade, I was able to "sculpt" the tile. The tool has minimal vibration which helped eliminate chipping. I imagine that if lightsabers existed, this is what it would feel like - wherever I waived the tool, the tile just disappeared. Amazing.
