I've had to take mine apart several times when the switch stops working. Banging on the switch area sometimes gets it working again. Seems to be a common issue. Absolutely love this tool when it starts up though. Super useful for so many things.

I see it at $99, but it's $129 when I add it to my cart. Is there a coupon code I'm missing?

How is this tool different from angled grinder with cutting wheel?

Not much different, just more ergonomic for things like long cuts in wire fencing and sheet metal, and cutting pipe more precisely.

The revamped website (from a couple of weeks ago) and new cart are quirky. Once you get to checkout the price should be correct. It also has weird caching where it remembers stuff you removed from the cart or forgets stuff you add. So just be especially diligent when you checkout to make sure there are no surprises on what you are ordering and its price.

Such a versatile tool. I just used it to cut out tile that was adhered to concrete. Setting the depth was easy and the vacuum port is a nice addition. I felt I could do it with the angle grinder but it would have been far messier and I would have risked going too deep. This was the right tool for the job.

I have this unit. I researched many different manufacturers and Dewalt was hands down the best. I only use mine occasionally but happy with it.

Love this tool. Also have the angle grinder but this is the one I always use. Used it to cut rebar, construction steel pipes, metal brackets, ceramic tile, etc. Im sure I've cut other things but its great to grab, pick the right blade, and make short work of fine detail cuts. The tile I cut was for about 100x 3in x 6in subway tiles. Worked great and made straight lines. Fits well in the hand.

Are the wheels proprietary?
