Just to add to all the positive comments about Dremels I use mine for a multitude of things. Have cut of a number of exhaust systems for replacement. Cut slots into stripped screw heads to put a flat head screwdriver into. Cut off bolts. Sand down fiberglass repairs. Grind off body rust. And the list goes on. Just got a flex shaft for it am hoping to go where no dremel has gone before.
my wife bought me the Black and Decker knock-off and it is the biggest piece of crap ever. Within the first half hour of use, the bearings were smelling. I wasn't bearing down on it either. The switch doesn't work either. To turn it on, plug it in. To turn it off, unplug it. Very unhandy and somewhat dangerous. I have used a Dremel at work and never had these problems with it.
Man, talk about an indespensible tool!!! I have used mine for so much its worth double what I paid for it. Once I discovered whoever replaced or removed the starter for whatever reason didn't know how to use the right size socket and BOTH bolt heads were completely rounded off. I used the dremel to resurface the edges into the hex shape to remove the bolts. What a headacke that was solved relatively easy. I can't even imagine trying to figure out a way of removing the top starter bolt any other way since it is wedged into a tight spot that you can't even see let alone get any tool into. The dremel also saved my butt removing a pitman arm that refused to come off after breaking a pitman arm puller even after I tried the heating technique. The dremel cut it off with pricision accuracy that didn't even tough the splines on the shaft. I don't know how anyone could function without a dremel tool.
Well I have'nt used a Dremel on my truck yet but I do know that you can do all kinds of things with it in regards to modifications of things.
I used mine a lot modifying my computer case as this is my other passion. Wish I could show some pics of my computer as well as my truck in my gallery to show you all.
They are great for modifying thin sheet metal and plastics like what are used in dashboards. I once used mine to put a CD player in a 1969 Mercury Comet. Worked great and it look like it was factory done when finished. None of those ugly black ABS adapter brackets or anything just a nice clean dash.
I've found it to be very useful. It can reach tighter areas than larger grinders. The thicker cutting wheels are superior to the thin brittle ones. I would like to get an air driven angle grinder like those used at work but the air useage is tremendous. No home air compressor is going to keep up as these tools are supplied by 3/4 inch lines.
I glance at the 4 1/2 grinders but they too are too big for many tight engine areas.
I used my Dremel to cut off muffler mounting bolts. It took awhile but between the cutting wheels and grinding stones I won.
i just recenly used my dremel to cut off my old muffler to put my redhot on, it cut my 2.5inch pipe inless than a minute, and it doesnt shoot out near the amount of sparks that a angle grinder does, so i felt comfortable working near my gas tank and i wasnt worried about leaving a big crater in my driveway. i also used my dremel to cut the window in my computer, its about 8.5x11 and i used maybe two of the reinforced cutting wheels. the dremel is nice for that small, detailed work.
They're great for smaller jobs, but aren't quite up to snuff for say, porting cylinder heads by themselves. However they do a great job getting into spots where I would have had to shell out $30-40 for a carbide bit to fit my die grinder. They will start overheating with too much coninuous use. Mine runs so hot now I can't hardly hold it without a set of gloves on after using it for 15 minutes. I'm sure the flex shaft ones have a bit of an advantage here since they're not right next to the work where the tool will draw in all kinds of dust into the motor and bearings.
My only gripe is the cost of the bits. Most of them are $4-5 and the grinding and sanding bits don't last very long. Reinforced cut off wheels are ungodly expensive! I only use them when I absolutely must and stick with the emory cut offs for most things.
