I needed to wallow out a muzzle brake for a 50 Beowulf to fit over the barrel and this is hardened steel. The Machinist that did the first work said that it was really hard and then he wouldn't do any more, so I had to do it by hand and these really work well. They don't tear up real easy they're very good quality and they last a long time it's a good deal.

Not too unhappy with the purchase as the price was very good, but the bits just don't last too long for average grinding jobs. I do normal things like grinding away protruding finishing nails or small screws and a groove is quickly carved into the stone. The array of sizes and shapes is a good touch though!

ANYONE GIVING THIS PRODUCT 3,4 OR 5 STARTS IS A SHILL !!!!!Using the smaller diameter grinding wheel with my Dremel and guide to sharpen 3 mower blades, 2 edges each. One wheel disintegrated before the first edge was done and 2 more had the adhesive holding the wheel to the shaft come undone before the second edge was done. Never had that happen in years of using grinding wheels. 4 grinding wheels to sharpen one blade. Continuing with the 4th wheel and letting it cool frequently, made it thru the first edge on the second blade and wore too thin on the second edge & had to be replaced. 5th grinding wheel, even with frequent cooling had the adhesive give way on the 3rd blade first edge. 6th grinding wheel, frequent cooling just made it thru the 2nd edge but is wore too thin to use again. So, 6 grinding wheel, 2 worn out, 1 disintegrate and3 had the adhesive between the grinding wheel and the shaft fail. Along the way the shafts kept slipping in the holder and damaged the guide I was using. It will have to be replaced. I never had that happen before either AND it was always tightened hard. You be the judge if this is sufficient quality, I will be returning the lot and will buy official Dremel replacement in the future.

I gave 3 stars because you get alot of them, you'll need them if you plan on doing medium to heavy sanding/grinding. I wore 1 bit out in about a minute sanding some soft wood in a guitar cavity & it wore out quick. You can see it in the pic next to a new one. But it did the job & I still have alot left. Depending on your needs, I'd recommend this for fine polishing & light sanding but anything other than that not so much.

I had some pottery pieces get fired before I had a chance to trim them, these tools worked perfectly for smoothing the edges and bottoms of the bowls. Great deal for the use.
