Undersized shank. WILL NOT fit a 1/4” collet. Eccentric junk. Also the media loaded up on mild steel.I can excuse some of the quality issues but lying on the description (shank diameter) gets you one star.

Shaft size is .230. That’s not 1/4 inch as in description. 1/4 inch is .250 in decimal measure. Also every one that I received had a non centered shaft. They wobble. This is pure junk. Amazon needs to remove this from their inventory. 🤬🤬🤬🤬🤬🤬

Read the reviews and you will see people saying these are out of round - the shank is not centered with the axis of the grinding cylinder. Know this: These reviews are dead on correct. These are junk. Chucked them in my drill and oh my - uh uh. Not using those. Total junk.
