      A:  I have a Dewalt, a Craftsman, and a Fien and it fits all of them so I would think it would fit a Bosch.

          The wood cutting blades are not very good, I think the cutting teeth should be more reinforced, or the same material to cut metals.

          The Dremel oscillating tools fit into other brands, including Milwaukee. As multi-tool sets go, this one is pretty good. If provides a range of oscillating heads for various jobs that a DIYer might run into. From sanding to cutting, the heads are long lasting. The heads have to mounting locations, which allows for an extended length for hard to reach places. I put this set through the paces with a wood floor repair and I was quickly able to cut out the old floor, tooth in the new floor, and sand things up without having to remove the floor trim molding. Thumbs up.

          I am a big fan of the oscillating tools, and purchased one to assist in installing vinyl laminate flooring. . This pack of accessories is just what I was looking for as an addition to the tool I bought. A key feature is that they are a universal fit and go with my non-Dremel tool. In addition to the quality of the blades and the variety in the pack (some for wood, metal, and drywall), I especially liked the "Dual Interface" feature which allows for either a quick connect, when needing to switch out blades regularly, or a more "secure" connection for doing heavier cuts. The two features are both contained on each blade using two different holes on the blade. I have attached a picture to clarify. Another added feature that comes in handy is the built-in ruler on the regular cutting blades. This allows you to be more precise on your plunge cuts. All in all, I am very pleased with this set

          The Mulit max universal oscillating tool accessory set is fantastic. Ten accessories are included in the carrying case. I've used them on sheet rock removal and repair, wood trim precise cuts, baseboard cuts and so much more. I've kept the carrying case to store all my oscillating tools. It's very convenient to have. The blades are universal so they fit most popular brands. This set has 6 blades, 3 sheets of sand paper pads and 1 diamond abrasive pad. My overall experience has been comfortable to say these blades work well in very tight places. It really gets the job done and with ease.

          The oscillating tool, for a long time I thought it was a gimmicky toy, I've since changed my opinion, it's one of the most used tools I use. It's super flexible and does a great job cutting, and has replaced a couple of hand tools, namely my drywall saw and my pull saw. I reach for it when a small cutting job comes up, and as a result I go through a lot of blades. The blades included here are good quality, you get two semi circular drywall blades, too wood cutting blades, one wood/metal blade, a scraper, and 4 sanding options. The blades have a couple of unique features, first, they are designed to fit MANY different tools systems. Each tool manufacturer seems to have their own attachment pattern; I can confirm these fit my Ryobi tool, even though it isn't mentioned on the package. They also have graduated depth marks, handy when you're doing a plunge cut and want to check your depth. This is a good value based on the blades alone, the sanding options are a bonus in my opinion. A good choice if you're just starting out with your oscillating tool or if you need to replace some dull blades.

          Went to Home Depot and bought this set in a pinch, since the blade that came my tool started showing serious wear after 1 month of use of plunge cuts in hard cherry wood flooring and about 20+ nail cutoffs. Using this Dremel blade for less than a week of light usage, it looks worse than the cheapo blade that came with my tool! Besides about 20-30 plunge cuts into the cherry wood flooring, I used it for one nail (by accident, the nail was in the wood I was cutting), and you can see from my pictures the results. In the first photo, blade #1 is the original cheapo blade (which still has some teeth after 1 month), blade #2 is this Dremel blade (almost completely worn out), and blade #3 is the unused dremel blade for comparison. In the second picture I just show the worn out Dremel blade next to an unused blade. To be fair, I've only been using the oscillating tool for a little over a month, so I'm not sure how these blades compare to other brands. But I do know that compared to the one that came with my set, this performed much worse. For the price, I would have expected better quality and more longevity.

            This is a nice kit, full of the attachments I use regularly. My cheap knock-off oscillating tool is not a Dremel but all of these fit fine. They even feature two different attaching points for different tools (see picture). I have tried cheap attachments but they don’t last nearly as long as these do. $39 may not sound cheap but it beats the heck out of buying the attachments separately.

            Great kit, compatible with a lot of brands This kit would be for someone who has oscillating tools(OT)/multi tools by more than one company. The blades are designed to fit pretty much all of the brands that I am familiar with((Dewalt, Ridgid, Milwaukee Ryobi, and etc.) The top half of the blades fit : Milwaukee, Dremel, Bosch, Makita, and Rockewell osc. tools. whereas the bottom half is for : Dewalt, Fein, Porter Cable, Ridgid, and Ryobi There may be other brands that are compatible, but according to the package and my personal tool(Ryobi) those are the brands that are guaranteed to work with this. I used one of the blades with my Ryobi O.T. and it fit into the bottom half of the blade. This worked very well, the blade sit nice and firmly in the tool, when in use it did not wobble which ensured a nice straight cut. There are depth guides, well numbers on the sides of the blade so you know how deep you are going, while in use the marks are hard to see , the saw dust was almost the same color, just stop and blow it off. I used this on a piece of 2x and it had no problems making the cuts. Went right through and it fit firmly into the oscillating tool.
