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

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.

I like them very well

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

Worked perfect for what I needed

Does what it needs to. Item works exactly the way it should. No complaints.

Great mechanism for release and tightening.

Fits my drills. Well made. I like the locking pins, drill wont slip and makes for easy removal when you change drill sizes. I have ordered two sets of these. I got so tired of always swapping them to different size drills

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

Great craftsmanship.
