M-jump 10 PCS CUT OFF WHEELS 3 x 1/16 x 3/8 - For Cutting All Steel and Ferrous Metals.10-Pack

The metal ring pops off easily. Blades fly off dangerously while in motion.

Work great! Im still on my first blade after cutting through about 20 1/4 stainless steel rods.

Not sure what makes a good one or not, but these cannot cut thru 1/16 sheetmetal. I have an older 3 disc that cuts as you would expect as it wears down. This brand simply does not work...go and find another brand to use.

These cutting discs seem to work as well as the brand names for a better price.

Good grind.
