I didn’t want to be too hard on the Speed Slot design of this Lenox kit too much, mainly because it doesn’t affect the actual functioning of the tool, but it’s actually a popular point of the product. Construction workers and the like all agree that removing the plug from your hole saw is inconvenient, and frankly, annoying as hell.
The Speed Slot design of these Lenox hole cutters let you slide the plug out easily so you can get back to work and avoid major delays.
On top of that, the entire makeup of the saw attachments is top-notch. They use bi-metal construction, so the high-speed steel teeth are welded onto the carbon steel base. This gives the product a long life – even with extended use.
Lenox really upped their game with this version, adding thicker walls, more power, and sharper teeth. And while the saws got better, the price hardly changed from the last version – always a plus.
These saws easily cut through softwoods, hardwoods, and even heavy gauge steel and sheet metal, leaving behind a clean cut with no burn marks.

This Milwaukee tools brand kit is high-quality stuff for sure, but it’s important to note that it’s definitely a general-purpose kind of tool. By general purpose, I mean that you shouldn’t try to drill through a thick piece of sheet metal using these saws.
The set does apply bi-metal construction, which is good stuff. It’s also designed for increased wear resistance and uses radiused tooth backs, which lessens the stress on the teeth. Also, the angled teeth make these saws more aggressive – another excellent point.
I’m also a big fan of the slot geometry, which lets you easily pry out the plugs using a screwdriver. Overall, this makes any project go smoother and faster.
All of that being said, you’re likely to get a long life out of these saws – as long as you don’t push it on the materials you try to cut. Stick to soft and hardwoods and thinner metals, and you could easily reach the promised “50% longer life.”
This heat-treated carbon steel set is ideal for lighter projects to achieve a precise, clean cut. One of the best parts about this hole saw set is the smooth edges you can achieve in mere seconds.

The HYCHIKA 19-piece hole saw kit is going to be the best for your budget here, in terms of simple home projects. It’s ideal for anyone looking to fix up something on their own, even with minimal handyman skills.
The high-quality set doesn’t include as many saw sizes as the others on our list, but they are heat-treated, wear-resistance carbon steel pieces that boast sharp teeth for 25mm of cutting.
As I mentioned, this tool works fantastically for simple materials like softwoods, plywood, and plastic. However, I wouldn’t touch this thing for anything harder, denser, or thicker. Why? The easiest answer is that it just isn’t made for the tough shit.
If you’re a serious construction professional, or at least a high-grade handyman, steer the other way and head towards our first choice. If you’re a mediocre handyman who likes to do projects around the house, then this is a great starter tool for you.
Hole Saw Kit Buyer’s Guide
Let’s be honest: buying new tools is tricky. With so many products and brands on the shelf at the hardware store, it’s hard to know where to start. Which tools are going to give you the results you want, and which are going to crap out on you?
The best way to keep that second thing from happening to you is to be in the know. I know you’re chomping at the bit to get started on your project, but trust me when I say, it’ll be worth it to read on and maybe get to what features to look for in the best hole saw kit.
Types of Hole Saws
When it comes to drill bits, you’re generally going to be looking for a specific size – and that’s about it. As far as hole saws go, there are so many more options beyond sizing (which we’ll talk about in a minute)
Let’s look at the different kinds of hole saws that are out there.
Carbon Steel Hole Saw
Carbon steel hole saws are going to be your cheapest type of hole saws. Saving money is a plus, but you also have to understand that low prices usually mean cheap quality. Depending on your project and the results you’re looking for, a cheap hole cutter might not do the trick.
Carbon steel hole saws are mainly used on wood, plasterboard, plastic, or softer sheet metal. You really shouldn’t try to use them on anything stronger than those materials, considering how flexible they are.
Carbon steel hole saws also wear down the fastest of any hole cutter. As I said, you get what you pay for.
Bi-Metal Hole Saw
A step up from the carbon steel design of the first hole cutter, bi-metal models use high carbon steel paired with high-speed steel teeth. They maintain the same flexibility as carbon steel, but they’re a bit more durable.
Since these cutters are made to be more heavy-duty, you can use them on a wider range of materials. Bi-metal hole saws are good for wood and plastics, along with steel, aluminum, copper, and cast iron.
Single Tooth Hole Saw
Next up is a hole cutter that uses just one tooth, instead of a ragged set of teeth around the whole thing. While you might think that more teeth equal better results, the one-tooth design is actually super effective.
In fact, one tungsten carbide tipped tooth cuts a hell of a lot better than the carbon steel teeth. It can move five times as fast through wood. It also makes a mess out of cement sheeting, which is impressive.
The only downside here is that you have to clear the material off of it several times while you work.
HSS Hole Saw
HSS holes saws are some of my favorite tools when accuracy is key. If you need a clean hole, this should be one of your go-to options.
HSS stands for high-speed steel, so with these drill attachments, you’re getting a fast, hard, and durable hole cutter. It’s perfect for cutting steel and alloy, and lots of professionals use it for electrical work.
TCT Hole Saw
Tungsten carbide tipped hole cutters are tough – no doubt about it. If you need to drill a hole through something dense like stainless steel, fiberglass, and other thick materials, this is the saw to grab.
TCT hole cutters are actually slightly different from TCT hole saws. They fall between saws with lots of teeth and the single tooth hole cutters. These cutters have just a few tungsten carbide tipped teeth, making them awesome on ceramic tiles, timber, and fiberglass.
These bad boys can typically cut as deep as 20mm.
Adjustable Hole Cutters
With an adjustable hole cutter, you’re going to be using something that looks extremely different from any other saw. The sharpened tip sits in the middle, while the cutting blade is attached to an arm on the outside.
The great thing about this different design is that you can adjust the cutting blade arm to match the diameter than you need. It might look a little weird, but it can get the job done on wood, plastics, rubbers, and vinyl.
Plus, some adjustable hole cutters use a tungsten carbide tip that can cut through ceramic tiles and plasterboard.
Depending on the specific kind of adjustable cutter you get, you can sometimes cut as deep as 125mm. The most common models hit just around 10mm, though.
When you’re buying a new product, it’s common to come up with a few questions along the way. Questions are how we learn, so go ahead and ask away! We’ve put together some of the most frequently asked questions about the best hole saw kit, so you don’t have to go scrolling through the internet yourself.
What materials can hole saws cut through?
Like we learned above, hole saws can cut through tons of different materials, depending on what they’re made of and the style of their teeth.
Some of the common materials a hole saw can cut through are wood, plastics, plasterboard, sheet metal, steel, aluminum, copper, and fiberglass. Super strong hole cutters can even make their way through the tough shit, like cement sheeting and ceramic tiles.
Can I sharpen my hole saws?
Let’s get this out of the way and say, you can sharpen any kind of blade. Even though hole saws attach like drill bits, they really function as a blade.
That being said, sharpening a hole saw can get a bit tedious. You have to file each tooth individually. If you’re like me and don’t always have the best patience, you can take it to your local hardware shop and have them sharpen it for you.
Are hole saw drill bits universal?
The best, most high-quality hole saw sets will be universal, meaning there’s a good chance they’ll work with the drill you already own. Many of them use a quick-change system that lets you attach your hole cutter without needing any other kinds of tools or parts.
Of course, some kits might use adapters to make sure that they work on any kind of drill. Adapters lock onto the hole saw, and some of them do require other tools.
Generally, as long as you have your arbor to connect the hole saw to the drill chuck and the help of a pilot bit, you should be good to go.
