6 1/4 inch Hole Saw, Bi-Metal & Heavy Duty Hole Saw with Arbor Mandrel, Hole Drilling Cutter for Cornhole Boards, Metal, Drywall, Plasterboard, Wood and Plywood

I got the bi-metal set and so far they works absolutely perfectly

The metal that the blades are made out of is pretty thin and they seem to dull quickly with minimal use. Nice to have as a more disposable pack but wouldnt count on it for any thicker metals or anything of that sort.

Used a dozen times and no issues so far

Dont expect this to last you a long time. We have used one blade and it was beginning to dull before we even cut through the side of a cabinet (particle board, not even hardwood).... So, I expect well get about one use out of each size we have to use. Didnt expect it to be disposable but thats about what it is. I worried when I got it because the shank was huge .... but the chuck on my husbands Craftsman did manage to open enough to hold it - definitely a 1/2 shank on the mandrels.

I got these to help with our kitchen remodel. We installed LED puck lights in the overhead up above our upper cabinets. The hole saw zipper 6 holes through the plywood. Very fast cutting. Nice clean holes. The hole saw remained plenty sharp after drilling out the 6 holes. The storage case is also very nice. It closes very securely keeping everything neatly organized and ready for action.

Great product Great quality Nice attractive case and set

This was a massive set of hole saws. Lifting them up is like a pandoras box of blades. The set comes with just about any size you might need, so that is a plus. When first trying to use, it was a little difficult. For some reason the bolt that secures the saw screws in the opposite direction. This also caused problems for me when trying to cut my hole. Since the threads were going opposite the norm (left instead of right), the motion of the drill kept causing the bolt to spin off. After several tightenings of the bolt, I was able to complete my hole. If you are looking for a value priced hole saw set, this one is a good deal. But you may need to fidget with it a little to make it work perfectly.

Broke one of the supplied bits on my 3rd hole. Installing a new door lockset. Expected better for the cost.

I used it to the exhaust fan,it’s ok,but not too fast to dig a hole

This is a heavy duty high quality hole saw. I have purchased several bi-metal hole saws but this is extra heavy duty and included an arbor mandrel. Some people commented here that this hole saw did not work well on metal. I used this hole saw to cut 22 gauge steel and it worked great. Highly recommend this hole saw.
