Hole Saw Set, 22PCS Hole Saw Kit with 3/4" to 5" (19mm-127mm) 13Pcs Saw Blades, Mandrels, Installation Plate, Drill Bits, Hex Key with Storage Box, Ideal for Soft Wood, Plywood, Drywall, PVC

First of all, you'll notice the price, these are not industrial level items. If you need something for occasional hole, this is an awesome product. The variety of sizes and simplicity of use is great. I've busted out a few holes already, they work great.

Nice combination of assorted sizes of hole saws in one kit. The larger hole saws are a little thin but satisfactory for the hobbyist. Professionals may need to look elsewhere. For my needs they worked perfectly.

Low quality, but worked for the projects I had

Very good!!

I bought this kit because I needed a variety of sizes for a renovation project and didn't want to spend a fortune on individual saws. For the price, you get a lot of pieces and the storage case is actually quite nice to keep everything organized. ​However, the quality is definitely "budget." It works perfectly fine on drywall and thin PVC, but it really struggled with 3/4" plywood. The blades dull relatively quickly, and I noticed some burning/smoking even when going slow. The larger saw sizes (4" and 5") are a bit flimsy and tend to wobble in the drill, making it hard to get a perfectly clean cut. ​If you just need to cut a few holes in drywall for lights or cables, this is a 5-star value. But if you plan on cutting a lot of wood, you might want to invest in a higher-quality set. It gets the job done, just not elegantly.

Works great

While I haven't had to cut through anything hard, it worked great for my small project. I like how the kit is packaged into a compact case. There are large sizes which I may be able to use for future projects. Overall, a good kit.

I would suggest you do not buy this. I have a long life of tool usage and this tool broke the very first time I used it. An I am a guy who has built many of my own tools by myself. So the flaw in the engineering here is the way the arbor is connected to the whole saws. It's not done the way standard tools are done. In this one, you can see in the lower left of the picture, there is a rectangular plate with a flat sided hole in the middle of it, and pins on the end. The purpose for this plate is that the flat sides of the interior of the hole, are supposed to match up to flat sides on the outside diameter of the arbor that holds the center drill bit. I used this tool one, single time. Using the largest saw in the pack, I drilled 3 holes through 3/8 inch plywood that was clamped to my workbench. Which trying to drill the forth hole, the arbor spun inside that plate and rounded it out. Making the entire set completely worthless. Meaning the amount of material that they used to lock that arbor in place, was ridiculously insufficient. If you look at all the good products available out there, I bought a set at a hardware store, they don't have this plate at all. They have a ring with pins. So I bought a medium price arbor and just the one size saw I needed. It was certainly more expensive than this is but the price of this one was the cost of the product, the ending of my project on the day I needed it, and then driving around to buy another product that was correctly engineered. So, I've no commentary on the seller or the manufacturer but the design is entirely insufficient. I have a machine shop here so I will likely build a new plate for this one that will hold up with the smaller saws. People who only want the smaller sizes might find they last for a little while, but is my opinion as a metal worker, that this is a very bad took investment.
