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

used for drilling large holes with hole saw.

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.

Had I known the ring sizing was so small and limited I would not have purchased this. Good concept though.

la altura de la broca con es compatible con las comunes (es mas pequeña) y no funciona

Great valve and good quality

Great craftsmanship.

this product i use on wood

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 perfect for what I needed
