Dado Blades: The Comprehensive Guide For Beginners

What are Dado Blades? Everything you want to know

You’ve probably heard of dado blades, but what are they exactly?

Dado blades are a specialized type of blade that is used to create dadoes, or grooves, in wood. Dadoes are essential for many woodworking projects, such as cabinetmaking, and these blades are the best way to create them.

This article will explore what dado blades are, how they work, and some available different types. By the end, you’ll know everything there is to know about dado blades!

What are Dado Blades?

Dado blades are a type of saw blade that is typically used in woodworking. They are designed to create dadoes and grooves cut into the surface of a piece of wood.

Dado blades typically come in sets of two or three blades. These blades are mounted on a circular saw and rotated at high speeds. When the blade is spinning, the teeth on the blade will cut into the wood and create the dado groove.

What are Dadoes?

Dadoes are horizontal or vertical grooves that are cut into the wood. They can be used for various purposes, such as combining two pieces of wood or creating shelves and compartments inside cabinets. Dadoes can be cut using different types of saws, but dado blades are by far the most effective way to create them.

How Do Dado Blades Work?

Dado blades consist of two parts: an outside blade and an inside chipper. The outside blade does most of the cutting, while the chipper cleans up the dado groove’s edges. Dado blades can be used with either a table or a radial arm saw.

Here is the step-by-step guide to using Dado Blades;

Step 1 –  Start by Measuring the Width of Your Dado Blade Stack:

The first step is to measure the width of your dado blade stack. Most dado blades have an outer and inner blade, with two or three chipper blades in between.

You’ll need to remove the throat plate from your table saw to get an accurate measurement. Once the throat plate is removed, you should be able to see all the blades in the stack.

Step 2 – Adjust the Depth of the Cut Knob on Your Table Saw:

Once you know the width of your dado blade stack, you can adjust the depth of the cut knob on your table saw accordingly. For example, if your dado blade stack is 6″ wide, you’ll want to set the depth of the cut knob to 6″ as well.

It’s important to note that you should always err on the side of caution when setting the depth of the cut knob. In other words, it’s better to set the knob slightly lower than your actual measurement than it is to set it too high.

Step 3 – Install Your Dado Blade Stack onto Your Table SawArmed with the correct measurement:

You can now install your dado blade stack onto your table saw. Be sure to follow all safety instructions that come with your tools and equipment—including your dado blade—to avoid injury. Once your dado blade stack is installed, you can reattach the throat plate.

Step 4 – Time to Make Some Cuts!

Now it’s time to make some cuts! Begin by setting up a test piece of wood so you can get a feel for how deep your cuts will be. Remember, it’s always better to start with shallower cuts and then adjust as needed rather than going too deep too quickly. Once you have a good feel for how deep your cuts will be, you can begin cutting dadoes into your workpiece.

Different Types of Dado Blades:

There are many different types of dado blades available on the market, each designed for specific purposes. Some of them are discussed below.

Standard Dado Blade Set:

The standard dado blade set includes two outside blades and one chipper blade. The outer blades are mounted on the outside of the arbor and do not protrude past the chipper blade. This configuration is best suited for cutting dadoes that are up to 1/2″ wide.

Wobble Dado Blade Set:

A wobble dado blade set is similar to a standard dado blade set, except that the outside blades are mounted on a ring that allows them to wobble slightly. This wobbling motion creates a somewhat wider kerf than a standard dado blade set. Wobble dado blade sets are best suited for cutting dadoes that are up to 3/4″ wide.

Stacked Dado Blade Set:

A stacked dado blade set includes two chipper blades and two outside blades, which are mounted on top of each other on the arbor. This configuration allows for a very wide kerf, making it ideal for cutting very wide dadoes or rabbets. Stacked dado blade sets can cut dadoes up to 13/16″ wide.

Stacked vs. Wobble Dado Blade Set:

There are a few key differences between a wobble and stacked dado blade sets. The most obvious difference is that wobble blades are mounted on a single arbor, while stacked dado sets have two or more blades that are mounted on individual arbors. This means that wobble blades can give you a wider variety of dadoes since they can make cuts at any angle, while stacked dado sets typically only offer straight cuts.

Another key difference is that stacking blades creates a much cleaner cut than wobbling because the blades are perfectly aligned. Wobble blades tend to leave slightly rougher edges, which can be problematic when you’re trying to achieve a precise fit. Finally, wobble blades.

Different Sizes of Dado Blades :

Now that we know what a dado cut is, let’s talk about the different sizes of dado blades that you can use to make them. Dado blades come in a wide range of sizes, from 6″ all the way up to 30″. The most common sizes are 8″, 10″, and 12″.

So, which size should you use?

The answer to that question depends on two things:

  1. The width of your table saw’s throat plate opening
  2. The thickness of the wood that you’re cutting.

The throat plate is the metal piece at the back of the table saw that surrounds the blade. Most throat plates have an opening that’s wide enough to accommodate an 8″ dado blade. However, if your table saw has a smaller throat plate opening—say, 5″ or 6″—then you’ll need to use a smaller dado blade.

The same goes for if you’re cutting thicker pieces of wood; in that case, you’ll need a bigger dado blade so that all of the teeth can make contact with the wood.

Here’s a quick reference guide to help you choose the right size dado blade for your project:

  • 6″ throat plate opening = 6″ or smaller dado blade
  • 8″ throat plate opening = 8″ dado blade (most common)
  • 10″ throat plate opening = 10″ or larger dado blade
  • 12″+ throat plate opening = 12″ or larger dado blade

How to cut a groove into the wood?

The best way to cut a groove into wood is with a table saw.
To do this, you’ll need to set the blade height so that it’s just slightly above the thickness of the wood you’re using. Then, align the blade with the edge of the board and slowly push it into the board while keeping your hands close to the fence. You should then be able to gently pull the board towards you as you guide it along the length of the blade. This will create a nice, even groove in your wood.

What are the Table saws that can accept dado blades?

Most table saws can accept both standard and dado blades, but some models are specifically designed to accept only dado blades. If you’re shopping for a table or saw, be sure to check to see if the model you’re considering can accept dado blades.
