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

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

replaced old ones

Fits all my brands of hole saws. Prongs really help secure the hole saw. Easy to use and so far very sturdy.

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

I like them very well

Great craftsmanship.

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

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.

Worked great out the box. Easy release system make the job quick. Would definitely buy again.

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
