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

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.

I purchased to cut thru a steel door all I got was a lot of sparks

Bought this set to do a plumbing project, but I also wanted to have a variety of sizes on hand. This seemed like a nice homeowner quality set. looks very nice and complete...but you better have a drill with a 1/2 chuck. They give you two mandrels in the set and I figured the smaller one would fit my 3/8 drill. Nope. They are both too big! Luckily I have a big hammer drill with a large chuck so I was able to use the set for my project. Thats all well and good but there are a lot of places this monster drill would not fit. I only used 1 size for three holes and it seems to cut clean without much effort. I cant speak to longevity, but quality seems reasonable at the price. Bummer about the mandrels.

This complete kit is excellent. Very sharp cutters. It includes an inch and a quarter, which many kits leave out. Super value. Highly recommended.

This is not a 6 and 1/4 inches hole saw its wrong it measures out to 6 and 1/8 inches not what I need I need it to be exactly 6 and 1/4 inches

Worked for a bit, thought I busted my drill press, it caused it to overheat. Was not really impressed with this at all. Thankful I just had to let the drill press rest and it still worked. But I only used it that once. It sits in the garage collecting dust now.

Creo que sólo cortan queso

Used a dozen times and no issues so far

all i need , except 1 5/8 bit, for my work needs

Definitely worth the purchase
