How to Choose the Best Hole Saw For Cutting Thick Metal & Stainless Steel
It's crucial you get the hole saw that would suit your needs. You wouldn't want to spend your hard-earned dollars on a tool that won't benefit you. Therefore, quickly go over these key factors to consider before choosing the best hole saw for cutting thick metal and stainless steel.
Buying a hole saw from a well-known, reputable brand is important to getting value for your money.
You wouldn't want to get a hole saw from a brand that doesn't back up their products or has terrible customer care. So settle for a brand that has proven to deliver high-quality products and have a fantastic customer care service.
The construction of a hole saw determines its ruggedness and also how fast and smooth it will cut. Most hole saws in the industry are constructed from bi-metal.
Bi-metal hole saws are a combination of soft, spring steel and high-speed steel (HSS) teeth for cutting through different materials and providing longer life.
HSS is used for the hole saw teeth because of its high resistance to wear, while soft, spring steel is used for the hole saw body because it absorbs impacts, which is important when drilling holes in tough materials.
There are different kinds of HSS, and the one used by a manufacturer in making a hole saw will determine the performance of the hole saw. However, you should look out for how many holes a hole saw will cut before it requires a replacement.
The hole saw design has to do with the mounting mechanism and the slots it has for removing slugs and plugs. A hole saw with wide, angled, and offset slots is user-friendly as it allows easy access to remove plugs with the aid of a screwdriver.
Furthermore, to use a hole saw, you'll require an arbor and often a pilot bit. Arbors, or mandrels as some people call it, mount the hole saw to a drill chuck. Some hole saws kit comes with a universal mandrel for mounting all the hole saws in that kit.
However, some mandrels have a tool-free quick-change mounting mechanism, while some will require nuts and wrench to mount onto a drilling machine or a saw.
The difference between the two mounting styles is that the hole saw with a tool-free quick-change mandrel doesn't require any tool and mounting to a drill chuck is a stress-free process. However, it may not attach firmly to the drill chuck.
The other mounting style that requires a wrench and nuts to mount is stressful but will attach more firmly to the drill chuck.
Hole saws mostly come in a kit with different sizes. You must check the available sizes of hole saws a kit contains so that you know the size of holes they can produce if it matches your project needs.
There have been situations where people buy a hole saw kit, and they didn't get one or two sizes important to their woodworking project. So, to prevent this from happening to you, check the sizes of hole saws in a kit.
Thankfully, we listed the sizes of hole saws in each hole saw kit reviewed on our list. You can always go back and check the sizes.
The price of a hole saw is also another important factor to consider. In reality, you get what you pay for.
But, some cheap hole saw kits offer equal or more excellent value for money than most of the expensive ones.
That said if you are a DIYer that wants to take on a one-time project in your home or office. You should opt-in for cheap ones that would still perform well.
However, if you are a professional, then go for the expensive ones that have been proven to stand the test of time.
This factor may not appeal to you at the initial stage of buying a hole saw kit. But, along the line of use, when a particular size of a hole saw, or a part of the kit gets damaged or missing, then you'll understand how important this factor is.
On an occasion where you misplaced or damaged a part of your hole saw kit, are they easily replaceable? This is an important question you need to ask before choosing a hole saw/hole saw kit.
Make sure there are replacement options for the parts of the hole saw kit you will be buying.
A carrying case is important to store your hole saws safely and also for easy transportation. Having one come along with your hole saw kit is vital.
Thanks to the invention of hole saws, making holes in different materials is as easy.
However, the drilling machine you attach your hole saws needs to produce enough power to drive it effectively through the metals.
When you combine the right hole saw with the right drilling machine, you'll get the cutting performance you desire.
In conclusion, we have reviewed each hole saw on our list thoroughly, covering all the important aspects. We also educated you on how to choose the best hole saw for your need.
If you made it to this point, we are sure you have found the hole saw that best suits your project and budget.
