Benefits of Using a Dado Blade
There are some advantages of using the best dado blade set out there that other tools can’t handle. They include:
Ease of Use
Unlike other power tools used to cut wood, dado blades offer a design that lets you make joint cuts, grooves, and rabbets quickly. You may also make various slots in the wooden project with a dado set.
A dado blade set is reasonably easy to use, so it’s no trouble to set them up. Most sets come with a guideline in the package. Even if they don’t, you can figure it out yourself or watch online videos to learn what you need.
Plus, a stacked set fits in most saw tables. You can also make a makeshift one if you don’t have the right table. Generally, you’ve got wood lying around, so it’s not hard to do.
On top of that, a dado blade set offers excellent accuracy, which means you get cuts that are precise. This is often tough to do with other tools. In fact, you don’t have to put in tons of effort to line up the slots in the wood piece with stacked sets.
You’re sure to appreciate that the dado blade set features high-quality construction. Therefore, it lasts longer than other products, and the edges stay sharp, too.
Not all dado blades give you a great performance, so you’ve got to be careful and choose the best dado blade set you can get for the budget you’ve got. To do that, you need to focus on a few things:
Before you start looking at blades, you must understand the types available. You’ve got two options – stacked dado sets and the wobble dado blade.
Stacked sets are what woodworkers prefer because they’re precise and easy to maneuver. They’re stacked because one blade is right next to the other. Between them, you have at least one chipper blade, though you may have more.
Depending on the manufacturer you choose, the units come with 18 to 40 teeth.
The wobbling is why it’s called a wobble blade. Because of that, they can produce inaccurate cuts. Therefore, most professionals don’t consider a wobble blade for wood-cutting projects that require a cleaner groove.
The number of teeth dado blades have can impact the cut on the wood. With higher-density teeth, you can have smoother and finer cuts. Plus, the number the disc has can depend on the size of the blade. Typically, there are more teeth with a bigger blade.
Generally, the market offers dado set options between 6 and 8 inches. An eight-inch blade is the most popular becomes it gives deeper cuts than the other ones.
The overall sharpness of the dado set is another crucial factor. You don’t want something that can’t cut through various hardwoods, do you? That’s why you need to think of how sharp the dado blade is. When it’s sharper, it’s easier to get through the wood piece.
Cut Quality from Outer Blades
Most dado blade units offer a jagged cut. If that’s the case, you must look for hook angles. If you’ve got negative hook angles, the two outer blades produce splinter-free cuts and offer a flat, smooth cut for the wood piece.
You want the dado set that you’re investing money into to be durable and last a long time. Therefore, if you find something that chips within a few uses, this is an expensive mistake. Overall, it’s crucial to think about how long the dado blade might last.
It’s best to think about the material used in its construction. While most of them use hi-density carbide, some might not. You can also find TiCo carbide, which is a bit stronger and mixed with titanium.
While you can find options made of stainless steel, they often lose their edges quickly and aren’t the best choice.
Compatibility is also crucial before making a purchase. It’s important to know the saw table’s arbor size so that you get a dado set that corresponds with it.
Otherwise, you have to return the dado blade, which can be a big hassle because you’ve got to wait even longer to start using the machine. You may also incur return shipping costs, which isn’t a good thing.
While most blades on the market cut different sizes, some of them also include an adjustment knob for on-the-go changes. However, they may still have issues getting the cut width you require at that time.
Therefore, you must think about whether the dado blade you buy can cut the width you need or not. This is often shown on the packaging, so you can check before you purchase it.
Professional woodworkers don’t need an instruction manual, so they may not care. However, if you’re new to dado blades and bought a new saw table to cut precision grooves, you want a manual to help you figure out what to do.
Manuals talk about the installation process for the dado set and about the adjustments it can make. Therefore, it’s a touch easier for beginners to get started.
Which Blade Type Is Suitable for You?
Since there are two choices, it’s completely based on preference. However, wobble versions aren’t often accurate, and professionals prefer to use a stacked dado set. They’re often easier to work with and produce a more accurate and precision cut. With that, experts who create wooden pieces of art should definitely go with dado blade sets that are stacked.
Other than that, it’s up to you which size dado blade you like most. Eight inches is the most common, but there are so many other sizes that might fit your saw table better.
What Type of Saw Is Used to Attach the Blades?
It doesn’t matter if you have the best dado blades if you don’t have the right radial arm or table saw! While some people have had luck attaching dado blades to circular saws, it’s not recommended. However, if that’s all you have, and you bought the wrong blade, you may want to give it a try. Generally, though, it’s better to work with the right tools to achieve a flat bottom and smoother cut.
What Safety Measures Should You Follow?
You shouldn’t remove the throat plate to use the dado blade. With that, you need to ensure that your arbor nut is secured and tight. Remember, the blades run at high speeds, so you want to keep a safe distance from the unit while you work.
What’s a Rabbet Joint?
The rabbet joint is a groove that’s often cut at the edges of your workpiece. Any dado set should be able to cut one, but it depends on the user’s skill level. They’re generally two-sided when you view it from a cross-section.
Can the Dado Blade’s Teeth Chip Off?
Even the best dado blade can have the teeth chip off the blade. Though it’s often associated with low-quality materials and non-durable products, it sometimes happens during the shipping process. When you receive your products, make sure to inspect the blades carefully.
What Are the Most Common Joints Made with a Dado Blade?
There are four primary joints available:
- Dado – Dado joints are the most common, and some think it’s the easiest. This is a slot or trench you make into your wood’s surface. When viewing it at the cross-section, it has three sides, and you may cut across or perpendicular to the grain.
- Finger – Finger joints are sometimes called comb joints. To make it, you must cut corresponding rectangular slots into two pieces of wood, joining them with wood glue.
- Tenon – The tenon is a rail that is formed at the end of a wood piece to insert into a square or rectangular hole that you must drill out of another piece.
- Rabbet – Rabbets are recesses or grooves where woodworkers cut the end of the wood. When you view it from the side, it seems two-sided and is open to the surface edge.
When you’re cutting grooves in wood items, accuracy is crucial. Most people focus solely on precision and don’t mind spending a bit more on tools that help them achieve their goals. When you choose dado blades, you get incomparable precision.
After learning about the stacked dado blade and the wobble one, you’ve got a clearer picture of why people like the stacked version more.
Whether you have your eye on a particular set or aren’t sure what you need, the best dado blade set is the Oshlun SDS-0842. It’s an 8-inch dado that has everything you need to get clean, flat cuts. Though it doesn’t come in a heavy-duty case, it does feature a compact plastic case to house the 42-tooth stack dado until you’re ready to use it.
