Good sanding bits last a while they get the job done

Good for beginner

The sand coating could be better ,but not bad for the price I paid.

They work very well for me to sharpen lawn mower blades. The width of the stones is very close to the sharpened area on my blades.

Good

Rubber part of the bits falls apart in use , I used four of them to sand 1/8 “ x1” of walnut

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.

Perfect for my projects
