Bi-Metal Hole Saw Kit, 16-Piece 3/4 Inch To 3 Inch Heavy Duty Steel Corn Hole Drilling Cutter Set with Drill Bit Adapter & Extension for Cutting Wood, Plastic, Aluminum, Metal Stainless Steel（SILIVN）

While I only needed the 2" hole saw the pricing and general good reviews led me to make this purchase.The kit comes in a cloth bag instead of plastic which has it's advantages and of course disadvantages. The different parts are in a foam which seems like it will work. I do have concerns about debris, oil etc contaminating the foam.The single saw that I used was used to cut a hole in a vintage non self defrosting refrigerator to install a gauge to check the internal temp without having to open the door/thus loosing some of the cold. It cut well and quickly.So far the only reason this gets 4 stars instead of 5 is that I didn't find a hex key included to adjust the pilot bit. I had a spare T-hex key and it fits nicely on top of the foam.All in all this seems like a decent unit.

The set is likely fine for wood or similar materials, but didn't stand up to stainless steel as described in the the description. The teeth were worn down before cutting through the material in spite cutting oil lubrication.Otherwise, a great selection of diameters and nice storage case with a heavy duty arbors and extension rod.

This set is great. I wish they would have added a 3 1/2" hole saw too. Sturdy saws and the case is excellent as these would be harder to store loose. They have sharp edges so be careful in handling.

The 2 pins on the large arbor #99010 are not drilled symmetric and do not fit any of the bits circular drills. The holes in the circular drill are symmetric. The arbor pins are close to being symmetric but they do not fit any of the large hole. This is the second one I purchased (sent the first back) The pins in the first set were way off. Looks like the manufacture simply tries to dill the two arbor pins by sight. The pins must be drilled symmetric in order to fit the symmetric holes in the drill bits. Poor quality control.

The hole saw wobbles when the drill is on making it impossible to place the hole where you actually want it. Luckily it didn't matter on this project. I would have returned them, but I was past the return date.

Every size that one could want to drill holes in wood, plastic, Sheetrock, etc.

All in one kit!Couldn't resist to try out - no regrets.Most common sizes (pipe vs saw) included, still going sharp.

I tired to drill into a 2x4 with the 1-1/2” and it couldn’t make the first hole. Than I tried to make a hole I to schedule 10 black steel pipe and it didn’t even make it a 1/4 if the way before burned up. Don’t waste your money
