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

seems like good quality workmanship. havent put it to the torque test yet.

These are cheaply made. Go with a better name brand.

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.

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

Five Star Great replacement to my Milwaukee and Lennox kits for a fraction of the cost. Tkx ~ Contractor rated item.

Great mechanism for release and tightening.

used for drilling large holes with hole saw.

Great valve and good quality

Pin holding it in place broke on first use. Cheaply made. Not worth it.
