A drill/driver has two speeds - high and low. There is a selector switch allowing the user to switch between high and low. High speed is used for drilling and low speed for driving screws.

cant use it
Cant get the primary screw off to install the blade. Way too tight. Ever hear of keep it simple...
by Eric
it is not made in US..
Ordered as tool made in USA. Web descriotion says “built in USA” and look for this logo, but all I can see “ Made in Mexico”... that is the reason I ordered from Home depot, to get US built tool, cause the better deals elsewhere... returning.

This will be a handy tool to own.
I had $150 worth of Home Depot gift cards from last Christmas and my birthday in May (my family knows what to get me). I held off using them until I figured out what I really wanted. I decided to spend them on this DeWalt oscillating tool as I will be helping my son renovate a 1930s house this fall/winter and I know sometimes there are oddball times when we'll need something like this. I liked that it was brushless, which should save on battery life and that you don't need a special tool to change blades. I already had 2 batteries for my DeWalt cordless drill, so I saved some money buying the tool only. It came with 2 blades, a bi-metal blade and an HSC blade (?) apparently good for wood. I wanted to repair the brick moulding trim on my garage door by cutting out the rotten area and cutting a new piece to fit instead of replacing the whole piece. So I cut out the bottom 10" with this oscillating tool without removing the trim on each side of the door (see photo). It cut right thru and it was nice to be able to control the speed with the trigger. It has a lot of power if you really squeeze the trigger! It was easy to control, too, and I got a nice clean even cut along my pencil line. The only neg I had was that the handle that you squeeze to change the blade is right where you want to hold onto the tool to make your cut. This might cause problems (broken blade maybe?) if you accidentally squeeze it too hard while you're cutting. I realized what I was doing and put my hand beneath the lever after that. Just something to be aware of. Maybe DeWalt could possibly come up with another way to keep the release out of the way when you're using the tool. All in all, though, despite its cost, I think I have added a good tool to my arsenal.

I am very happy with the tool itself, but Home Depot shouldn’t deliver power tools in the DeWalt box, the likelihood of it getting stolen was astronomical, with that said, I shop Home Depot regularly, and will continue, but when customers order expensive things, you should put them in a generic box, that won’t make it as much of a target please

SUPER TOOL
I use this oscillating tool for everything! It's light, doesn't use too much battery, and is easy to use. The only con is that you will wear through blades pretty quickly so buy extra. I love this tool though and am kicking myself for not getting one sooner.

Broke when I clipped it on my belt
Not impressed with the quality of Dewalt lately. I have been using Dewalt for the past 15 years and noticed the quality of the tools has gone down dramatically. This 240 dollar impact broke after clipping it to my tool belt. I take care of my tools. It wasn't dropped or anything like that. It just broke.
