As far as I can tell, this grinder will accept every 4 1/2 grinding accessory wheel that is available. If you do, just remember that the on switch is locked on, so if you drop the tool, it could be chasing you around the room. My only complaints are minor. I found it very easy to use and control. The arbor lock button is in a rather awkward place for me. Just make sure that you install the 7/8 arbor wheel so that it is centered on the backer, which has a little lip at the 7/8 mark.
Then install the locking nut, which also has a 7/8 lip to use on their 1/4 inch thick disc.To use a rubber backer for sanding discs, polishing wheels, fiber discs, you have to remove the backing nut. I use this one, Adjustable Pin Wrench because it's cheap but works just fine.You can also remove the guard, if needed to get at certain jobs. There are no spanner wrench holes in the locking nut of the Dewalt rubber backer. This grinder seems like a great value and I'm very pleased to have one. I wish that there were a threaded socket on top of the grinder for the handle, in addition to the 2 on the sides. It's small, light weight, compared to professional use grinders, while delivering lots of power and lots of wheels and brushes available for various uses, including heavy duty diamond wheels.
Many (most).of them are marked with a 7/8 arbor, which will work fine. It is retained by a rubber O ring and is easy to remove. The average home user will not likely find this unit lacking.The grinder is tool-less, if you use their rubber backer DeWalt DW4945 4-1/2-Inch Rubber Backing Pad with Locking Nut for fiber discs and sanding disks or if you use their grinding and cutting wheels that have an integral nut, like this oneDEWALT DW4522 High Performance 1/8-Inch Metal Cutting and Grinding Wheel that has the 5/8 - 11 arbor. You'd probably need another spanner wrench for the 3rd party backers. In both cases, the wheels can be installed and used with hand/finger tightening. The instructions are in the manual, but are easy to miss.
There are other rubber backers that do have spanner holes in their locking nuts, like the Bosch MG0450 4-1/2-Inch Sander Backing Pad with Lock Nut which I think are easier to use. That means you have to use finger pressure to tighten/remove it.
Plenty of power. it's handy for all those little tasks that you don't really have a good tool to do:-- Remove the paint from a metal porch railing-- Cut off the bolts from a toilet installation-- Grind the sharp edges of bolts on a playground set or childrens toy-- Sculpt wood to make unique objects-- Sand anythingAn angle grinder can be your "tool of last resort" for a whole bunch of tasks. fast.A grinder is a very handy tool to have on hand, and it's cheap;-- Cuts metal and stone.-- Removes paint-- Grinds/sands metal or wood-- Sculpt wood or stone-- Fit cutting discs, grinding discs or pads, sanding pads or wire wheels-- You can probably even use it to buff wax a carSo. Works as advertised. Not much else to say. Keep one on hand. It spins.
I bought it to use with a wood carving attachment and it does a good job of handling that. I own all kinds of DeWalt power tools and have been satisfied with all except this one. It has all the power I needed and everything else works fine but. I have not had much luck with getting a replacement as yet. the switch sticks in the on position.
I bought mine for wood carving with a Lancelot, which has a 5/8" arbor hole, which is very thick, and which required me to pull off the backing plate. However, THREADED 7/8" accessories won't work. PS. No reason not to give it 5 stars if it pans out. The grinding wheel that comes with it has a 7/8" arbor hole, but the grinder arbor is 5/8." There is a backing plate with a raised portion to enable acceptance of 7/8" wheels. Said plate is hard to remove (very tight fit; requires pliers) and first-time users might not even know that it is removable.I'll write more later; just thought I should get this on the record in case someone needs to know, as it's not explained well in the manual. I published the identical review for the reconditioned model, which is the one I bought, but everything I had to say about that applies to, and is useful for, this one. I've only had this thing a short time; so far, so good.
Please don't take this as a criticism of a dead man switch, I highly recommend that type if you are a casual user or inexperienced with power tool use - this grinder could cause serious injury if not used safely and properly.It does vibrate, but that is common with any grinder, however the vibrations for this grinder seem to be minimized are not that tiring to my hands. I bought this grinder for use on my job, I'm the Maintenace Supervisor at a multi-use building, and have used it for a wide variety of jobs - everything from simply smoothing out a sticking metal framed door to cutting through rebar when we did some major remodeling.This grinder is easy to handle, being small and lightweight enough to get into a tight spot yet still has the power for tough jobs. It has a simple on/off switch rather than a dead man switch but I feel that is a plus. I sometimes use this grinder for an extended period and like to shift my grip, I wouldn't be able to do that with a dead man switch.
