Join Ware Corundum Deburring Polishing Review

I didn't like that it didn't fit the 1/4" collet of a regular die grinder and I sent it back for a refund. Forwarders should be satisfied with this item.

Actually 6mm instead of 1/4" I mixed up the collet on my grinder and it came loose because I trusted the description. False advertising. They need to change it to 6mm instead of 1/4 inch to protect buyers in the future. It is not possible to return the product as it has been opened and used. Avoid if you don't have the right collet for it.

The shank discovered is actually 6mm in diameter, not 1/4, so the grinding head shaft was too small to fit my die grinder. I had to make a sleeve to use it. Partly my fault, the title says 1/4 but the description below says 6mm, the difference was enough to require a socket. Not very happy, something of a security issue. Otherwise and with the sleeve they worked fine.

Cones are not centered on their shafts and are not balanced for rotation. I'm trying to machine my own intake manifold, heads and headers. I will not have any success with these items, as you can see the aluminum I remove is only on one side of the cone shape which shows its flaws, don't waste your money on this. I will not ruin my parts by continuing to use those poorly made cones to grind, finish, or polish anything.
