Many years ago I burned up a Dremel after a satisfactory amount of work doi
ng carving and polishing. I bought another, and it wasn't as well made and
didn't last well, either. So I bought a rotary from HF. It was cheap, di
dn't last that long, but I felt like I got my money's worth out of it. How
ever, I was <<<really annoyed>>> when it died, and was even more annoyed I
had to stop working on my project because it simply quit.
I mentioned that to a guy that I know that does a lot of woodcarving, and h
e put me onto the Black and Decker RTX. Maybe I got a good one, I don't kn
ow. But it is about 20 years old and runs like it did when it was new. I
used it a couple of weeks ago to polish out and burnish the edge of a knife
with some metal polish and it is still as strong as the day I got it.
The hardest work day this tool had was to cut about 250 roofing nails off t
hat punched through 1/2" plywood decking. It burned a lot of grinding whee
ls up, but not the tool for that all day and a half job.
So what I am saying is that I would split the difference on the price of th
e Dremel and the HF, and get what I think is a better tool. And yes, all t
he Dremel bits (anything with 1/8" shank) will fit the Black and Decker.
Just my 0.02.
