mini saw issues

i got the mini saw and when i tighten it onto my 8220 rotory tool the entire piece free spins and i dont think it is supposed to do so..


Broke my dremel

I used this a couple times on small projects for thin wood and it worked fine. Then, I used it today to cut through a thicker piece of wood covered in vinyl flooring. The wood and vinyl combined were the exact max depth of the blade, so I expected it would have to work hard to get through it. On and off it would smoke from heat so I'd let it cool off and startup again. Then, the motor just died. Total use before it killed the motor was about 5 minutes. Clearly the blade was too large for my dremmel to handle. Like using the engine of a small sedan inside a tractor trailer. My dremmel is a corded variable speed 75th aniversary edition dremel, not sure which model number.


Works good

Only issue I had was the instructions. No where did it say what was included so I spent way too much time trying to find the screw and adapter only to find them in another package with more instructions. Using the arrow on the edge of the gaurd was pretty accurate.


One of the worst tools I've ever owned

I thought I could cut balsa and thin hobby plywood with this like a circular saw in construction. Have yet to be able to figure out how to use it, and there's no how-to documentation or support (I wrote). The plastic head rotates around the axis and makes the whole tool want to rotate backwards while being used. The blade guard has so much tension it's impossible to force it over the edge of a piece unless you use two hands and push hard. Once going it wants to stop and bind and I don't know what's stopping it. Not the 1/16 ply. I even tried putting the tool in a vice and using it like a table saw. I know how to use tools, but this one is beyond me. Nice gift for your worst enemy. To be fair, I did write about my problems and the retailer was willing to give me a full refund even though I had used the item. I declined thinking I could figure out. I couldn't.


Can't get it to work.

Just bought this tool. Read instructions, screwed it onto my dremel 285 and the shaft lock button won't work with the tool in place to add the blade and screw. Maybe I'm doing something wrong but you would think that it would work just like all my other accessories.
