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 bought these so I would have a mandrel with locking pins for my hole saw. They are very durable and very easy to use. Extremely happy with my purchase, and a great addition to my tool collection.

used for drilling large holes with hole saw.

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 mechanism for release and tightening.

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...

good replacement for some lost parts.

The fit and quality was good.

this product i use on wood
