What Is A Dado Blade?

Dado blades are a subcategory of circular saw blades designed to do specific tasks. Those tasks include cutting grooves and joints in wooden applications. That ensures these units have a high versatility level. Users can apply them when making slots for two parts to come together, such as drawer bottoms or sides, shelves, door panels, etc.

What type of saw uses a dado blade?

A table saw is the tool compatible with a dado blade. However, the compatibility will depend on the specifics of the saw and the blade. That is why you should compare the measurements and ensure they fit each other.

Types of Table Saw Blades

Understanding how saw blades meet specialized needs is crucial to picking the right one for the job. Below are some common types of saw blades you can buy.

Crosscut

Manufacturers design crosscut saw blades to make smooth cuts across the wood’s grain. These saws have more teeth and feature fewer gullets. A 10-inch crosscut blade may have 60 to 80 teeth, allowing it to make more cuts with each revolution than a ripping or a combination blade.

With fewer spaces between the teeth, crosscut blades remove less material, resulting in a smoother cut. It also means it takes these blades longer to move through wood. Crosscut blades are an excellent choice for finish carpentry and other applications that require precision and a smooth finish.

Flat-Tooth Ripping

Ripping blades are designed to cut along or with the grain of the wood. Since it’s easier to cut with the grain than against it, these blades feature flat teeth configurations that can quickly remove large chunks of wood. Ripping blades typically have 10 to 30 teeth with more severe teeth angles of at least 20 degrees. Fewer teeth on the blade allow for more gullets for removing material.

While this design makes ripping blades ideal for rip cuts, they are not ideal for cross cuts since they produce too much tear-out, (the amount of wood removed with each cut,) plus this type of blade often leaves behind ragged edges.

Combination

General-purpose combination blades can handle both crosscuts and rip cuts. Combination blades find a middle ground between crosscut and ripping blades with 40 to 50 teeth. While they may not be the best blade for ripping or cross cuts, they can do both effectively, eliminating the need to change blades mid-project. Combination blades work well for projects that demand both types of cuts but don’t necessarily need the smooth finish of a crosscut blade or the speed of a ripping blade.

Dado

A dado blade is a specialty blade used to create wide grooves in wood for shelving, door panels, and drawers. Whereas other saw blades consist of one flat metal blade, dado blades come in two different designs: stacked and wobble.

Stacked blades consist of multiple cutters and spacers sandwiched together to create a wider profile. Manufacturers configure stacked blades with ripper style blades and spacers in the middle and crosscut blades outside. This setup allows the blade to remove large amounts of material while maintaining a smooth cutline along the groove’s edges.

Wobble blades rotate in an offset pattern to cut wide grooves as they spin through the wood. Wobble blades include an adjuster that alters the width of the wobble. Although wobble blades don’t offer the same quality cut as a stacked blade, they are usually lower-priced.

What to Consider When Choosing the Best Table Saw Blade

Determining which table saw blade is right for your needs can be overwhelming. Read on to learn about the factors to consider before making a purchase.

Job Type

Most DIYers can get away with a single combination blade for all of their project needs. Combination blades make both rip cuts and crosscuts across standard lumber while leaving edges clean enough to meet most project demands. Combination blades also reduce the added cost of buying multiple blades and also save time by eliminating the need to switch the blades between cuts.

Ripping, crosscut, and dado blades offer more specialized cutting and are must-haves for many carpentry projects such as furniture, cabinetry, and built-ins. For jobs that involve a lot of ripping, purchase a ripping blade, which will save time and effort while still leaving a clean edge for joining pieces of wood. A rip cut blade is also ideal for cutting hardwoods as it will cut through this tougher material without wearing out the blade.

Keep a cross-cut blade handy for ultra-smooth carpentry cuts. Crosscut blades offer the cleanest cutting edge, making them ideal for woodworking projects that require precision cuts. A dado blade is a must-have for shelving, furniture, and cabinetry projects that require recessed grooves.

Blade Kerf

Kerf refers to the thickness of the blade. The higher the kerf, the more material is removed with each cut. A full kerf blade is 1/8-inch thick. Thicker kerf blades resist bending while moving through the wood; however, they require more power from the saw to work effectively. Most table saws can handle standard 1/8-inch blades. If your table saw is equipped with less than 3 horsepower, consider using a thinner kerf blade. Thin kerf blades require less power, are more precise, and create less waste with each cut but are more likely to warp while cutting through the wood.

Blade Length

Blade size does affect performance. Smaller blades on equally powered saws spin faster, resulting in smoother cuts. A 12-inch blade requires more power to rotate and is more likely to wobble than a smaller blade. As such, a larger blade won’t make as precise a cut as a smaller one but does offer greater depth, allowing it to cut through thicker boards.

Most tables saws use 10-inch blades, although there are some variances, so check your table saw before making a purchase. While it is possible to fit a table saw with a smaller blade, never attempt to equip a 10-inch table saw with a larger blade.

Blade Teeth Configuration

The configuration of a saw blade’s teeth affects how the blade cuts the wood. Flat top blades are more effective at cutting through wood. These blades rip out material in large chunks, therefore, increasing the cutting speed. Since they also leave ragged edges, these blades are a good option for rip cuts.

  • Crosscut blades feature bevels that alternate in direction, resulting in smoother cuts for finish carpentry.
  • Combination blades use a hybrid approach, which mixes flat top teeth with alternate bevel teeth. That allows the blade to make crosscuts and rip cuts but still maintain a relatively smooth edge.

In addition to these standard configurations, there are also specialized blades for cutting various other materials, including metal, masonry, and wood laminates.

Tooth Gullet

The gullet is the space between each blade. It determines how effectively the blade removes material with each cut. Blades designed to remove material quickly, such as rip blades, have deeper gullets. Precision-cut blades, such as crosscut blades, feature smaller gullets, and are designed to make smoother cuts.

Additional Features

Many manufacturers equip their blades with additional features that improve durability and performance. Look for blades that offer anti-vibration slots, which prevent warping during use.

High-quality blades will also offer higher-quality materials such as carbide-tipped blades. These hardened tips hold up better than other materials, which extends the life of the blades. Consider blades with lubricating coatings that improve blade life and allow for faster cutting.

Tips for Buying and Using a Table Saw Blade

When you determine what saw blade to purchase, there are a few additional considerations you should make to ensure your blade works properly with your table saw.

  • Identify how powerful your table saw is before you purchase a blade. A table saw with three or more horsepower is better equipped to handle thicker blades while a lighter-duty saw might be better suited for thinner blades.
  • Keep an eye out for hand-tensioned blades. These are blades that have been precision flattened by hand. Hand-tensioned blades offer the least amount of wobble and hence the highest grade of accuracy.
  • Pay attention to the material. High-grade materials such as C-4 carbide offer greater durability. While these may cost more, they’ll require less maintenance and will last longer.
  • When you cut wood, be patient. If you attempt to push the material too aggressively through a blade, it is dangerous and will also diminish the quality and accuracy. Be patient and feed wood into the blade at a pace it can handle.

How Does A Dado Blades Work?

If you are using a dado stack, check out the blades on the outer side. You will notice that there are more teeth than in the main chipper blades.

The difference compared to a standard table saw is that there should be an outer blade on the stack’s sides. It would help if you didn’t change these blades since that will compromise the operation. One of them is facing the outside, and you should turn the other one to the inside.

Now, the central blade will have fewer teeth. It is possible to adjust how many blades you want in the middle. That will affect the cut’s width. Once you are ready, activate the tool and start cutting.

How To Use A Dado Blades

Is it your first time using a dado blade? These are the steps to follow to ensure nothing goes wrong:

Before mounting a dado blade, turn off the table saw you are using. Make sure it is unplugged and disconnect it for your safety.

Place the blade on its highest possible adjustment. Remove the arbor washer and nut, as well as the throat plate. Finally, disconnect the blade you want to replace with the dado unit.

Insert an outer blade that is facing out first. Next, place the desired spacers and chippers in the middle to get the preferred setup. Finally, place the outer blade on the other side of the unit.

Ass the arbor washer and nut, and don’t forget to use a dado throat plate. Now, lower the blade.

Check if the flange, nut, and washer are mounted entirely on the tool’s arbor. Once you tighten the arbor, you should be able to expand it past the nut.

If using a dado blade set, it is critical to check if you have the desired configuration. The teeth on both the central chippers and outer blades should be staggered, and you should avoid aligning them since it can lead to chipping.

If you use a radial-arm saw instead of a table unit, the only difference is the blade guard. You should remove it instead of the throat plate, and don’t forget to use a guard for the dado unit.

Section 6 What Joints Can You Make With A Dado Blades?

An integral part of woodworking is joinery. It is a process where you connect multiple components. Before you use adhesives, bindings, or fasteners, it is essential to cut joints. You do that with a table saw dado blade.

The joints can vary in structure significantly. Check out the most common joint types below.

What are the joints?

A joint is a junction between multiple components of a framed structure. You will often find it in cabinetmaking and carpentry projects. The purpose of a joint is to connect two parts and hold them in place. The connection strength must be optimal and capable of holding on for long.

Dado and Groove Joints

Woodworkers often go with dado joints because they are easy to make with these blades, and they maintain a strong connection between the components.

Here is how a dado joint works – you start by making a channel with three sides in the first part. That channel goes across the wood’s grain, and that is where you place the other components into the groove. The connection strength is maximum because it utilizes three locations, and you also have extra space if you want to use glue.

Users often use these joints for shelves, bookcases, and cabinets.

Rabbet Joints

You can use a dado blade for a table saw to create a rabbet joint. It is where you make a groove along the component’s edge. Thanks to that, you can connect parts flush with an element. You should receive a wooden application with a lip that goes into that groove.

The great thing about rabbet joints is that they don’t make the connection obvious. It seems like components are from a single part, making them great for cabinet tops and other applications.

Check out this video that will tell you more about cutting dadoes and rabbets with a dado stack.

Tongue-and-Groove Joints

You use these joints when you need to connect wood components on a single level. Users make a groove in one board to place the tongue protruding from the other component.

Tongue-and-groove joints are an excellent choice for parquetry, paneling, and flooring projects. Their main application is whenever you need to keep a flat surface while bonding multiple wooden components.

Half-Lap Joints

If the project requires connecting wooden components that cross each other, this joint will help maintain their faces flush. It is better to use this joint that a miter saw.

The method involves cutting 50% of the thickness of the wooden components to connect. Once you do that, you connect them to create a flat surface. You might need to add glue for an extra bond.

How To Choose The Right Dado Blades Set?

The best dado blade is the one that fits the specific requirements of your project. It is why you should know how to pick a suitable unit.

Here are the factors to consider in the process:

Size

You can pick between the following cut widths – from 7/8 or 13/16 to ¼.” A standard-sized blade is adjustable to fit different widths.

Apart from that, consider the diameter, which can go from six to ten inches or more. The reason why the diameter is important is that it determines cut depth. The bigger it is, the deeper the cut will be. The price difference isn’t that big, and having a large blade can be useful because you will have additional depth options available.

Scoring blades

If we say scoring blades, we are discussing the cut quality with the desired tool. The scoring blades are on the outside of the unit, and they can vary in the number of teeth and their geometry and configuration.

The configuration includes beveled teeth, but you will also find flat raker units between them. You will find the beveled teeth pointing outside, and that is because they only cut one shoulder. The number of teeth can be anywhere from 11 to 40 or more, and it is up to you to find the desired option for your project.

Tooth geometry

The teeth shape can determine the cut specifics and quality. You want to consider a hook angle, which can vary from -5 degrees to 30 or more degrees. The standard seems to be 20 degrees. You will find that this angle is the tooth’s position’s position to the blade’s center.

Some tools even have a negative hook angle, and it can be beneficial when cutting plywood. If you don’t want to chip along the shoulder, you will benefit from this unit.

Chippers

The chippers have an important task of eliminating the waste between the scoring blades. Thanks to that, they ensure a flat surface. It is why their teeth are flat, too.

Please note that chippers don’t have anything to do with a shoulder cut. It means you don’t need as many teeth per blade, but you can pick between two and six. The bigger number of teeth on the chipper ensures a flatter surface on various applications.

Numbers

The more chippers you have, the longer the cut will be. You want to consider the number of chippers, which can be from two to six. An affordable deal might be going with three units that have a moderate width.

When it comes to the width, you won’t find wider ones than 1/8.” However, you will often find chippers available in 1/16 and 3/32.”

Shims

You can use these spacers between the blades to achieve a higher level of precision and accuracy. That can be useful when you are aiming for cuts that might not be that standard. If the need comes to tailor the blade to the application’s specifics, you can do that with shims.

If you look at shims, they are discs made of steel, brass, plastic, or paper. Their task is to determine the cut size to the smallest detail by putting the arbor between the chippers and the outside blades.

The bottom line.

Ultimately, there is no one-size-fits-all formula. Make sure to consider the desired application, and pick a dado blade set accordingly. It would help if you began by assessing the features you need. Once you establish that, it will be easy to find a suitable tool.

You might need different types and sizes of dado blades for various applications. That is why you should go for the most versatile setup possible. Alternatively, you can acquire multiple blades to be ready for every project type in the future.

FAQ of Dado Blades– 6 Inch Dado Blade VS 8 Inch Dado Blade

Are you wondering if you should use a small, standard, or large dado blade? The truth is it all depends on the desired project. Thanks to these units’ various configurations, they are incredibly versatile and adjustable to any cutting width and material thickness.

For example, you can use a 6-inch dado blade for materials where you don’t need a too wide cut. On the other hand, an 8-inch dado blade is considered the standard size in the industry. These can achieve a decent cut width since they have a larger diameter. Ultimately, you should pick the unit that fits your project’s requirements.

We gathered answers to the most common questions people ask about the dado blade. Check them out if you want to learn more about these tools!

Is a Dado Blade Necessary for Woodworking Projects?

It is not necessary for woodworking projects, but it can make your job easier in many situations. If you need to cut joints used to join two wooden components together, a dado blade can do a reliable job. Although it is not required, many operators trust this blade to deliver optimal performance whenever cutting joints.

It shouldn’t be a problem to set up a dado blade if you follow the article’s instructions. Alternatively, check the manual you received with the product to safely discover how to place the blade on the tool. Always stay safe while operating, and don’t forget about wearing protective goggles and other safety equipment

Is Using a Dado Blade on a Circular Saw Dangerous?

Dado blades are compatible with radial-arm and table saws. That means you should avoid using them on circular and handheld tools! If you do that, you will compromise your safety. You don’t want to risk getting injured or something else going wrong while operating, so make sure not to use a dado blade on circular saws.

Can Any Table Saw Use Dado Blades?

No, not all table saws are compatible with a dado blade. Additionally, your table saw might not be able to fit all sizes of dado units. For example, some tables can fit an 8-inch dado blade, but cannot accommodate bigger items. Always check the details of both the tool and the cutter to ensure they are compatible.

FAQs About Your New Table Saw Blade

Changing blades, making the right cut, adjusting your kerf; read on to find the answers to your most pressing concerns regarding table saw blades.

Q. Why do I get wider cuts than the blade kerf?

If you get wider cuts than the blade’s kerf, it’s likely because the blade is wobbling under the pressure of cutting. Eliminate the wobble by purchasing blades that feature cut-outs to help reduce tension.

Q. How do I change a table saw blade?

Changing a table saw blade is done by applying a socket wrench to the large nut holding the blade to the table saw. Most table saws include a locking button or mechanism that immobilizes the blade so you can loosen this bolt. If not, use a second wrench to hold the bolt’s head in place while you loosen the nut.

Q. How do I use a dado blade on a table saw?

Begin by stacking the blades and shims to the thickness of the groove you’re trying to create. Make sure to keep the shims and chipper blades on the stack’s interior and the saw blades on the exterior. Install the blades as you would a normal saw blade and adjust the height to achieve the exact depth of cut you need.
