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

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 craftsmanship.

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

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

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.

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