  • Electric die grinder

    I'd like to get a variable speed electric die grinder with a 1/4" collet. I have pnuematic one, and it works great. The Dremel just isn't stout enogh some times. Plus I have a few felt bobs that are 1/4" shanks. Anyone have any experience with something like this? Thanks.

    my only experience with a elec. die grinder was bad but i can only blame the tool because it was a very 'cheap' tool and that is what we got for quality. if you buy a name brand one it should be fine. also look for a foredom tool if possible. they are pricey but it is what the dremel wants to be when it grows up

      If you want to go this route get a good one not a cheap one you will be more happy in the long run. I use both the air and the electric.. at the shop i am all air power at home i got both..

        In that case maybe you can answer my question about what compressor is minimum for keeping up with a die grinder...?

          Yes the Foredom would be great. Might have to check on an easy payment plan down at Lowes though, that's a little steep for me right now. And I agree, I don't think I'd waste my time and money on anything else. Guess I'll stick with the Dremel and a die grinder for now. Later on.

            I got rotary it pumps 125psi right at the pump..

            But you would need to get a compressor that will hold a good bit of air and run it around 75-90 psi ..

              I borrowed a 1/4" drive Dewalt drill from work that turns 4000 RPM and it's been working great. I just have to be careful not to hit the chuck up against the work piece. I'm using felt bobs w/emery and it's creating "lines" in the aluminum. How do I go about getting them out? Should I use another bob with another compound? The bobs are getting the glazed look on them, do they need to be cleaned or should I get another one? Thanks. Later on.

                hey steve the trick on the chuck is to wrap it in duct tape. as for the bobs leaving lines it should work out on the next coumpound. and the glazing is just like the wheels, they need to be cleaned from time to time. i use a straight screwdriver blade(gently) or they will shred.

                    Steve,


                    I clean my felt bobs by laying a piece of 80 grit sandpaper on my work bench and running the bob over it. I also use the same 80 grit sandpaper to shape the bob to get into those hard to get into places.

                        I was using the screwdriver method also, gotta try the sandpaper trick though. Thanks for the tip John.

                          Good one. I use a fine hacksaw blade but the 80-grit sounds good too...

                            I've had great luck with the Dremel model 732 with the foot control. I bought it used from an online auction sight. I know they come up for sale quite a bit. The shaft features interchangable handpieces. You will need the model 236 handpiece to have a 1/4" collet.
