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

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.

Low durability

First time I used it (on wood) this happened...

Check the exact size you need to cut out holes for LED spots. I needed a cut-out for 8 LED, but this one did not fit. The hole is too small and I will need to buy another hole saw. This hole saw is 203 mm.

This is good basic hole saw kit to have when you need to make cut some rough holes. Comes with plenty of sizes and is easy to attach and begin drilling right away. The teeth are not very sharp or fine so its better suited for softer materials and drywall. Against harder materials, it does seem to struggle as you attempt to cut deeper. But it works and has a good variety of size options. The case is quite generic and poor to where the saws will fall out if you open it on the wrong side. Good set for basic home use.

This was bought for my spouse. He has not had a chance to use them, but when he does, I will update my review.

Definitely worth the purchase

Used a dozen times and no issues so far

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.

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.
