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

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

replaced old ones

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

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

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.

Great deal, does the job quickly and effectively

Good set

this product i use on wood

Great valve and good quality
