Rated 4.3 out of 5 by 10 reviewers.
Rated 5.0 out of 5.0 by Cuts and stays sharp for a long time I've had this bit for years now and have used it on steel, brass and acrylic. The latter is notorious for dulling bits but this bit has kept working and working. Keep thinking I'll need to finally replace it but it's still good. It is expensive but considering how long it lasts I think in the end it's a bargain. September 12, 2015
Rated 5.0 out of 5.0 by Awesome little bit I was making some mounting brackets out of 1/4 steel, and my bolt holes were a little out of alignment. I didn't want to drill up as they weren't that far off, so I decided to try this little beauty. I was able to stretch the holes for a perfect fit. I was amazed how well this thing cut through 1/4 steel, like a hot knife through butter. The only down side is that it generated hundreds if not thousands of little metal slivers or splinters from cutting. I ended up pulling about a half dozen out of my hands because I was to hard headed to get some gloves. So if your cutting fairly thick metal, you may want to make sure you wear gloves and a long sleeve shirt to protect yourself from the material. As always, wear eye protection. December 2, 2014
Rated 5.0 out of 5.0 by CR 89 The drill was expensive but did the job easily. Would buy agaibn. March 12, 2015
Rated 5.0 out of 5.0 by Great grinder ripping I use this bit for grinding and hogging out brass and steel and there is not another bit that I have tryed that works so good. It is a must have bit for anyone serious. September 25, 2015
Rated 1.0 out of 5.0 by Doesn't cut tile Bought this bit so that I could notch out a small "U" shape on some grade 5 floor tile. It wouldn't cut at all. It kind of just gnawed at the tile and probably would have taken me days to actually notch out what I needed to notch out. It will probably cut something weaker, but definitely does not work on tile. December 10, 2014
Rated 5.0 out of 5.0 by Another great Dremmel tool Great for fine use when working with ceramic tile. Would not try to do such intricate work without this. October 28, 2014
Rated 5.0 out of 5.0 by Tungsten Carbide Cutter The bit was very useful while I did not need to rent a tile cutter. It held up and glided through the ceramic tiles and grout. It is an excellent tool to have in your toolbox. April 15, 2014
Rated 5.0 out of 5.0 by Sharp and effective This cutter really made life much easier. Very powerful with smooth results. March 4, 2014
