Types of Dado Blade
A dado cutter will always come in handy when cutting joints, and so it will always make your woodworking projects easier. While our dado blade reviews above will make it easy to pick something high-quality to add to your power tool collection, there are many things you need to know about these tools and their blades. The first and most important is the different types available.
#1. Stacked Dado Set
The stacked dado set is what most woodworkers prefer to go for because it is versatile. It consists of two outside blades and some chippers on the inside which is what you use to give the cutting width a fine adjustment. The width that you get on the stacked dado will always depend on the number of chippers that you have between the outer saw blades. Most will have two outer blades and 4 to 6 chippers.
- Precision: If precision is your primary goal when making joints, the stacked dado set is the best for you. The presence of many blades ensures that you always get a very accurate cut and a perfect groove making it the best dado blade for most woodworkers.
- Long Lasting: Since the stacked dado sets use many teeth to make each cut, the edges do no wear out as fast as the wobble blades. Also, they do not require much re-sharpening, and this means that the woodworkers that use the stacked dado set will not need to replace them often.
- Expensive and Hard to Setup: Although the stacked dado set will always outperform the wobble blades, it is more expensive than the latter. The fact that it comes with many blades is one of the reasons that make it pricey. Also, the presence of several blades might increase the efficiency, speed, and precision of cutting but they also make the stacked dado harder to setup for first-time users than the wobble blade.
#2. Wobble Dado Blade
The wobbles dado blades only have one blade in the system that uses a different technique to make the groove instead of relying on stacking. And this entails installing one wobble blade with a hub that you can adjust to various angles. The angle makes it spin in a wobble unlike in the stacked set where the spinning is accurate. As the wobble blade moves back and forth at high speeds, it cuts away the material that it passes through to create a joint.
- Affordable: It consists of only one blade, and so it is way much cheaper than the stacked sets. Also, many companies make it, and so the competition also helps to make it affordable.
- Fast and Easy Setup: With the wobble blade there are fewer parts, and so the set up is easy and also fast. Most experienced woodworkers will not even need to follow the instructions to set it up for the first time.
- Less Accurate and Damaging to the Saw: It is almost impossible to achieve a good flat-bottomed and squared groove when using the wobble blade. Also, their design means that they cause more vibrations which can damage the saws by loosening fasteners and other parts of the saw.
How to Buy the Best Dado Blade Sets
A dado blade set is one of the things that every serious woodworker must have in the workshop. Most know this, and they also understand what they are all about and how to choose the best. However, if you are a beginner woodworker or buying one for the first, you might not know how to make your pick. But, understanding the points below will always make the blade choice easier.
#1. Type of Blade
The kind of dado blade should always be the first thing that you consider when shopping for the best dado blade set. Here you get to chose between a wobble and the stacked ones. Most woodworkers prefer the stacked ones as they are more accurate and create joints with a perfect fit but they are also more expensive than the wobble.
Dado blades have fewer variations than most other saw blades types, and so there are minimal compatibility issues. However, there are still a few essential things that you need to know when it comes to dado blades so that you can be able to match them to the right saws.
Saw Blade Specifications: When matching dado blade specifications like TPI (teeth per inch), blade material and hook angle you can follow the guidelines that you would use when matching a standard saw blade. In general, blades with a high TPI will be ideal for material that chip easily and the hard ones. Also, the more the teeth on the dado blade, the slower and finer the cut it will make and fewer teeth will result in faster but rougher cuts.
When it comes to the hook angle, most dado blades will have a 0-degree one as they are mostly for use with table saws. However, some can have -12 degrees and -5 degrees hook angles which make them suitable for radial arm saws. For the material, carbon, steel, and carbide are the most common ones and whatever your dado blade uses will determine what it can cut.
Diameter and Power: As a woodworker, it is vital to make sure that you match your dado blade to a saw that can to run it optimally. Most dado blades will come with a diameter of 6 or 8 inches. The larger 8-inch blade is ideal for deeper cuts, and it will require a saw like a cabinet saw due to its power and some types of or contractor saws to operate it. A 6-inch dado set, on the other hand, can work on contractor saws, cabinet saws and also with the portable and bench saws.
#3. Insert Plates
An insert plate is where the blades protrude from, and so it is an important factor to consider in your search for the best dado blade set. If you intend to use the blade on a table saw it would be necessary to install a customized insert plate. For this, you can choose between a pre-cut dado insert plate and a zero clearance one which does not have a pre-cut slot for the blade and so you have to make it with your dado blade.
6-Inch vs. 8-Inch Dado Stacks
If you do not have a lot of experience with dado stacks or you are buying your first dado blade set you are likely to face different challenges. The most common one that most woodworkers will face is whether to go for a 6-inch or 8-inch stack. Both these blade stacks will help you make some grooves and dados, but having some information about each will help you get the best dado blade set for your needs.
#1. 6-Inch Dado Stacks
The 6-inch dado stacks are the smaller of the two standard options available. Also, they are also lighter than the 8-inch, and this means that the saw does not have to work very hard to spin them. However, their small size means that they will not produce very deep cuts. But the quality of the cut that they provide is similar to the 8-inch stacks, and so you can still achieve almost any joint when using them.
#2. 8-Inch Dado Stacks
Most woodworkers will prefer to go for the 8-inch dado stacks because it looks more appropriate for their 10-inch table saw. Whereas it is bigger than the 6-inch, it still makes almost the same quality of cut, but it can make cuts that are up to 1-inch deeper than the latter. And so if you intend to be cutting deeper dados the 8-inch is the best option. However, it is noteworthy to know that the 8-inch stack requires a saw with a more powerful motor and it is also pricier than the 6-inch stack.

Most Common Joints with Dado Blade
#1. Dado Joint
The dado joint is the most common and probably the easiest to make with the dado blades. In its basic definition, it is a trench or slot that you make into the surface of a block of wood. When you view this joint in the cross-section, it will have three sides, and you can cut it either perpendicular or across the grain.
#2. Finger Joint
The finger joint is what many woodworkers will also refer to as the comb joint. To make this joint, you need to cut a set of corresponding rectangular slots in two pieces of wood and join them with wood glue. This joint is stronger than the lap joint, and you can visualize it by locking your fingers at a 90-degree angle.
A tenon is what makes the popular mortise and tenon joint possible. It is a rail that you form at the end of a piece of wood for inserting in a rectangular or square hole that you have to drill out in another piece. When making the tenon, it is important to ensure that it forms a perfect or exact fit for the mortise.
The rabbet is a groove/recess which woodworkers cut into the end of a piece of wood or any other material that the dado blade can cut. When viewing it from the side, it will appear two-sided, and it will be open to the edge of the surface.
