Thanks for the open box review. I bought one about a year ago refurbished from amazon. Was supposed to redo the grout in the shower, but project was put on hold. Recently I needed to remove an old, thick caulk line from around exterior house trim I’m replacing. My first approach was get the grout line started and pull it off by hand. But wood from the plywood facia came with it. Then I tried a chisel, then a scraper, both very labor and time intensive and not efficient. Fortunately, just as my arm was giving out, I remembered the dremel that was collecting dust in the garage. I put on the fine tooth saw attachment that came with the set and proceeded to cut away about 60 linear feet of caulk line in an hour or so. The fine tooth saw cut it off smooth, with only mineral going over again for no bumps and ridges. This dremel tool is not contractor grade but for the DIY around the house, it’s perfect. It is confortable to use and a good size and weight if you need to work overhead.

Ill vouch for it as well. Ive got one in the shop and while it doesnt get pulled out very often when it does get used its just the ticket. Ive also used them to remove an entire locker room worth of tile grout. We did blow through about 6 of them for 4 guys but they were being used 6 hours a day for 3 days.

Thanks bigbowwow for the comment. That is a prime example of this tool at work. I’m glad you got your job done before the arm fell off. I’m hoping to get a chance and test it out this week, maybe make another video of it at work, but who knows.

Have you guys tried the sanding attachment? Is it worth anything. The tool came with 60 and 120 grit pieces.

I think it was on the brink of falling off. It’s the risk for all DIY’ers.

I bought one a couple of years ago to cut back some baseboards so I could install some built-in bookcases without having to remove the entire baseboard, cut it down and reinstall it. It worked like a charm and has been one of my go-to tools ever since. I also use it for cutting holes in cabinet backs for electrical boxes.

My only complaints are:

1. It can get really hot during long runs
2. The blade lock nut will sometimes loosen and let the blade drop off.
3. The wood/metal blades wear out pretty quickly. Last week, I used it to cut off some screws holding a kitchen island to a hardwood floor. The screw heads had been wrecked when the island was installed, so cutting them was the only solution. Wore out two wood/metal blades cutting five screws.
