scottchen PRO Mounting Mandrel 3/8 & 1/4 Arbor Hole (2pack) for Type 1 Cut-Off Wheel 1/4 Shaft for Die Grinder Rotary Tool

I used mandrel with a diamond edge metal cut-off wheel. NO problem, cut off 12 - 1/2 U bolts on my RV. Tightened with a screw driver, they didnt slip.

Used this for 3 inch cut off wheels. I have only used the top without the insert. Works great at my shop for holding a cut off wheel.

Tried in all kinds of die grinders with no problems

I like that this part was available on Amazon. Hated having to purchase a new one, but had no choice as I had misplaced my old mandrel. Its rather small. Be sure to place it in a dedicated location whe through using it. Mine is going with my 90°die grinder in my air tool drawer.

The arbors were drilled and tapped the wrong size and will not tighten down. This is a complete waste of money. Very poor quality!

Good quality

Only one of six disc changes gave me a hard time undoing the screw

good for the 2 kutzall blade to fit the die grander

I use it with a cutoff wheel and it wobbles. Not the best... and my tool is not junk its a Standard Air Die Grinder (Blue-Point®)(brand new)

Stripped out the threads first time I used it now Im past my window of return but Ill just learn my lesson and go to Napa next time
