50pc GIT INDUSTRIAL TOOL MOUNTED GRINDING STONE ASSORTMENT BITS 1/4" DRILL MSA50

The item came in a box with 10 grinder bits in each of 5 ziploc bags. I took one of the bags and measured each bit.First, all the bits measured 5.8 or 5.9mm in diameter. 1/4 inch is 6.3mm, so they are all undersized. This doesn't matter to me because I plan on using it in my drill - a die grinder is a future purchase.The length of the shaft is 1-1/16 to 1-1/8" long, except the 2 flat disks (3rd and 5th on in top row) which are 1-1/4" long.The following are the dimensions of the grinding stone in inches (not including the shaft). They are listed as height x diameter (widest part).First row: 0.97 x 0.97, 1.23 x 0.77, 0.95 x 1.25, 0.73 x 0.78, 0.97 x 1.25Second row: 1.00 x 0.56, 1.23 x 0.77, 1.22 x 0.94, 1.05 x 0.75, 1.11 x 0.74There is some wobble in the bits, but not so bad that it is unusable. However, I would not use them for precision work. I use them for grinding metal parts down to size.

I like the product because there's plenty of them and it was well worth the money dislike was some of them don't work on stainless very well

Ok

We go thru a ton of these have pick them up at auto parts stores and hardware stores but not at this price

All different shapes to get into all areas of any project. Good quality as well.

Great price but every one is aluminium oxide abrasive. The description really didn't say. Was hoping for a few silicon carbide grinding stones to be in there. Disappointed

Specs are over actual size of items. A few were out of round or not centered on the shaft. Used in a drill they did what I needed but I would not use in an actual die grinder for safety reasons.

Needed more grinding stones for the Shop.
