Luckyway 3-Piece Hole Saw Mandrel,Fit 3/4-Inch to 6-Inch Diameter,Including 7/16-Inch and 3/8 Inch Shank Hole Saw Arbor and 3-Piece 1/4 Inch HSS(M2) Central Drills

Great mechanism for release and tightening.

Does not work with Lenox hole saws. Waste of my time

Great deal, does the job quickly and effectively

I used this product for installing sprinkler systems easy to use great product...

used for drilling large holes with hole saw.

Great valve and good quality

I should have known... more China junk!!

I bought these so I would have a mandrel with locking pins for my hole saw. They are very durable and very easy to use. Extremely happy with my purchase, and a great addition to my tool collection.

The fit and quality was good.

Good product for the value. The Milwaukee is much better quality if you will be using frequently but this is almost 1/2 the price.
