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

Great craftsmanship.

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.

Great deal, does the job quickly and effectively

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

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.

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

I should have known... more China junk!!

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

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.
