The Ultimate Dremel 9903 Tungsten Carbide Cutter: Unleash Your Precision Power! Review

Ideal for cutting steel. I've used it to enlarge screw holes in a 1/4" plate with no problems. But doing so also produces tons of very fine metal shavings. I got my hands on a few while holding the plate I'm cutting. Weeks later they are still there. Be careful.

Must have if you are a mechanic. I use these tungsten carbide bits in my dremel all the time to remove broken screws. About once a year I have to buy about 3 pieces to live another year. I pray they never stop selling them because I don't know what I would do without them.

Very cool tool. Used to extract a broken bolt extractor. A few tips: Don't use it like a drill, it will break. Perform circular motions at a low speed angle when using 3. It will take time, but be patient. It also helps to stop every now and then and clean the metal shavings with grease or WD40.

Never, never again will I file a hole. I had a hole in the 1/8" plate that had to be opened up. This little pup tore it up like butter. Crap.

Make them stiffer I'm hitting even though it's on two nuts I'm talking about bumper mounting nuts two deep cuts (mostly through) on both sides then I have she aborted. I also used a Dremel 9904 product for the same, so two sockets for two serious nuts, after that they don't cut the same xD, so with such a small but handy board can I please do some serious rust cleaning))).
