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 should have known... more China junk!!

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

Perfect for cutting through metal frames at work.im an comercial electrician and am constantly useing these wholesaws...

This product works exactly as I hoped it was. Unfortunately my drill maxed out at 3/8 and this bit did not fit, I wish I would have checked this first. Im not sure if there is a way to use an adapter but I easily found a drill to support it.

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

Worked perfect for what I needed

Great craftsmanship.

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

Great valve and good quality
