Circular saws are the most versatile power tools for carpentry and woodworking. Whether you need to make crosscuts, rip cuts, or bevel cuts, a circular saw can do it all. However, not all circular saw blades are created equal. Some blades are specifically designed for crosscuts, while others are optimized for ripping. In this article, we will focus on the latter and answer the question, which circular saw blade for ripping?
Before we dive into the specifics of ripping blades, let’s first understand what ripping means. Ripping is a process of cutting a board lengthwise, parallel to its grain. This type of cut requires a blade with fewer teeth and larger gullets (the spaces between the teeth) to remove the material efficiently without causing excessive heat and burning.
Now, let’s look at the different types of ripping blades available in the market and their features.
1. Rip-Cut Blades: As the name suggests, rip-cut blades are designed specifically for ripping cuts. These blades have fewer teeth, typically between 24 and 30, and larger gullets to remove the material quickly. Rip-cut blades are ideal for cutting softwoods, such as pine and cedar, and are not recommended for hardwoods.
2. Combination Blades: Combination blades are versatile blades that can handle both crosscuts and rip cuts. These blades have a higher tooth count, typically between 40 and 60, and smaller gullets than rip-cut blades, making them suitable for both types of cuts. Combination blades are ideal for cutting plywood and hardwoods, such as oak and maple.
3. Thin Kerf Blades: Thin kerf blades are designed to make narrow cuts, which makes them ideal for ripping thin strips of wood. These blades have a smaller kerf (the width of the cut) than regular blades, which means less material is wasted. Thin kerf blades are also less taxing on the saw’s motor, making them ideal for cordless circular saws.
4. Dado Blades: Dado blades are specialized blades that are designed to make grooves or dadoes in wood. These blades have two outer blades and a set of chippers in the middle that create the groove. Dado blades are ideal for making joints, such as rabbets, dadoes, and tenons, and can be used for both crosscuts and rip cuts.
5. Crosscut Blades: Crosscut blades are designed to make cuts perpendicular to the grain of the wood. These blades have a higher tooth count, typically between 60 and 80, and smaller gullets than rip-cut blades. Crosscut blades are ideal for cutting hardwoods, such as maple and oak, and are not recommended for softwoods.
Now that you understand the different types of ripping blades available, let’s look at some factors to consider when choosing a ripping blade.
1. Tooth Count: As mentioned earlier, rip-cut blades have fewer teeth than crosscut blades. When choosing a ripping blade, make sure to choose one with a tooth count between 24 and 30.
2. Gullet Size: Larger gullets are essential for efficient material removal during ripping cuts. Make sure to choose a blade with larger gullets to avoid heat buildup and burning.
3. Blade Diameter: The diameter of the blade affects the depth of the cut. Choose a blade with a larger diameter for thicker stock and a smaller diameter for thinner stock.
4. Kerf Size: The kerf size determines the width of the cut and affects the amount of material wasted. Choose a blade with a smaller kerf size to minimize material waste.
5. Material Type: The type of material you are cutting will affect your choice of blade. Softwoods require a different blade than hardwoods, and thin strips require a different blade than thick stock.
In conclusion, choosing the right circular saw blade for ripping is essential for achieving accurate and efficient cuts. Consider the tooth count, gullet size, blade diameter, kerf size, and material type when selecting a ripping blade. Whether you are a professional woodworker or a DIY enthusiast, choosing the right blade will make all the difference in your projects.

Frequently Asked Questions about Which Circular Saw Blade For Ripping?
What is the difference between a ripping blade and a crosscutting blade?
A ripping blade has fewer teeth and larger gullets, allowing it to cut through the wood quickly with the grain. A crosscutting blade has more teeth and smaller gullets, making it better suited for cutting across the grain.
What size blade should I use for ripping?
The size of the blade depends on the size of the saw and the thickness of the material being ripped. In general, a 7-1/4 inch blade is suitable for most handheld circular saws and can handle materials up to 2-1/2 inches thick. A 10 inch blade is better suited for larger saws and thicker materials.
Can I use a general purpose blade for ripping?
While a general purpose blade can be used for ripping, it is not recommended. A ripping blade is specifically designed to cut with the grain and will produce cleaner, smoother cuts with less effort. Using a general purpose blade for ripping may result in rough, jagged cuts that require more sanding and finishing.
How often should I replace my ripping blade?
The lifespan of a saw blade depends on the frequency of use, the type of material being cut, and the quality of the blade. In general, a ripping blade should be replaced when it becomes dull or damaged, as a dull blade can result in unsafe and inefficient cuts. It is also important to regularly clean and maintain the blade to ensure optimal performance and longevity.
