4 1/2 IN. Angle Grinder with Rotating Rear Handle
4 1/2 IN. Angle Grinder with Rotating Rear Handle is rated 3.9 out of 5 by 14.
Rated 1 out of 5 by from Died in less than a year I bought this tool in September 2020, and I've used it for cutting steel with cutting disks, grinding welds and surfaces with flap disks, and occasionally stripping rust with a cup brush. It was easily my favorite tool of the year, until this morning. I was using it with a flap disk to grind welds when suddenly it wouldn't shut off when I let go of the trigger. RPMs increased uncontrollably and it had just started to smoke when I unplugged it from the wall. I let it cool down completely, plugged it in again very briefly, and it wanted to repeat the behavior. Sadly I can't recommend this tool to anyone.

Rated 4 out of 5 by from Great balance and handling Today I used my AG454 angle grinder to level out a couple of metal spikes from a guard rail in my yard. The grinding was easy to do thanks to the ability to rotate the rear handle to a comfortable grip. Please note that this tool ONLY accepts type 27 - 6 mm grinding wheels.

Rated 4 out of 5 by from Great lil Grinder This is my second Ryobi grinder I have purchased. The first one was great except for one problem and that was the on/off trigger switch.I like the ability to turn the handle 90 degrees for grinding or cutting. Grinder is nicely balanced.

Rated 5 out of 5 by from Easy to use, works well I bought this grinder from Home Depot to trim off some oversized bolts. The price is right, the tool is very easy to use in terms of installing and removing the disc. It is powerful for my need. It is easy to handle. The handle can be switched for right and left hand use. It also doubles as the storage for the wrench. Great little tool for home use.
