Understanding Blade Size and Arbor
The diameter of the blade is an important consideration as it affects the cutting depth and the stability of certain applications, such as making dados and rabbets. Choosing a larger blade diameter provides more stability and allows for deeper cuts compared to smaller diameter blades. Most table saw blades have a diameter of 10 inches, which is suitable for most cutting tasks. However, if you need to cut thicker materials, such as over 1-1/4 inches, opting for a 12-inch blade may be necessary. It’s important to note that larger diameter blades may introduce some wobbling, reducing cutting accuracy, so ensure that your table saw can accept the size blade you plan to use.
The arbor size of the blade must match the arbor size of your table saw to ensure proper installation and avoid wobbling or incorrect assembly, which can lead to unsafe conditions. Before purchasing a new saw blade, always measure the arbor size of your table saw to ensure compatibility. Common arbor sizes for table saws are 5/8 inch and 1 inch, but there may be variations across different brands and models.
Types of Table Saw Blades – Based on Application
With several types of blades for table saws available, each tailored for specific cutting applications, understanding these different types will aid you in choosing the apt blade for your woodworking needs.
Rip-cut blades, also known as rakers, are designed for cutting along the wood grain. These blades have teeth with square top edges that attack the wood in a chisel-like motion. They are fast cutting and durable, making them ideal for ripping through lumber. However, they don’t produce a clean surface, so they are not suitable for fine finishing cuts.
Cross-cut blades are designed for cutting across the wood grain. These blades have angled teeth that shear the wood fibers cleanly, resulting in smooth, splinter-free cuts. They are often marketed as “all-purpose” blades and are suitable for a variety of woodworking tasks.
Dado blades are specialized blades used for making wide, flat-bottomed grooves or dado cuts. These blades consist of multiple blade segments that can be adjusted to achieve different width cuts. Dado blades are commonly used for joinery work, such as creating dado joints, rabbets, and tongue-and-groove joints.
Types of Table Saw Blades – Based on Tooth Configuration
Alternate Top Bevel (ATB):
Blades with an ATB tooth configuration have alternating beveled teeth, with one tooth leaning to the left and the next tooth leaning to the right. ATB blades are versatile and suitable for general-purpose cutting tasks, including cross-cutting and ripping in both hardwoods and softwoods. They provide clean and precise cuts.
Flat Top Grind (FTG):
Blades with an FTG tooth configuration have square-shaped teeth that are ideal for ripping applications. FTG blades excel at cutting along the wood grain, providing fast and efficient removal of material. They create smooth edges without splintering or chipping, making them great for rough cutting tasks.
Combination Tooth Blades:
Combination blades are versatile and considered “all-purpose” blades as they can handle both rip cuts and cross-cuts. They typically consist of a mix of tooth configurations, such as alternating top bevel (ATB) teeth and raker teeth, or a combination of four ATB teeth followed by one flat top grind (FTG) or triple-chip grind (TCG) tooth. This combination allows combination blades to provide clean cross-cutting action as well as efficient ripping capabilities. Due to their versatility, combination blades are a popular choice among woodworkers for a wide range of woodworking applications.
The Importance of Tooth Angle and Hook Angle
The tooth angle and hook angle of a table saw blade are crucial factors that can greatly affect the cutting performance and efficiency of the blade.
The tooth angle refers to the angle at which the teeth are ground in relation to the blade. Different tooth angles offer different cutting characteristics. The most common tooth angles found in table saw blades are the ATB, FTG, and TCG as discussed above.
The hook angle refers to the angle at which the tooth face leans forward or backward in relation to the center of the blade. The hook angle greatly influences the aggressiveness and ease of feeding the workpiece through the blade.
Positive Hook Angle:
Blades with a positive hook angle, where the teeth lean slightly forward (around 20°), provide an aggressive cutting action and a high feed rate. These blades are ideal for ripping tasks and are commonly used in table saws.
Negative Hook Angle:
Blades with a negative hook angle, where the teeth lean back slightly (around 6°), offer a slower feed rate. This helps prevent self-feeding or “climb cutting” and is beneficial for radial arm saws and sliding miter saws, which require less aggressive cutting actions.
Table Saw Blade Materials and Coatings
Carbon Steel Blades:
Blades made from carbon steel are known for their durability and strength. They can withstand heavy use and are suitable for cutting through various types of wood. However, carbon steel blades tend to lose their sharp edge more quickly compared to blades made from other materials.
Tungsten Carbide-Tipped Blades:
Tungsten carbide-tipped (TCT) blades are incredibly popular in the woodworking industry due to their exceptional durability and extended edge life. These blades consist of steel bodies with carbide-tipped teeth, which provide excellent cutting performance and longevity. TCT blades are ideal for cutting hardwoods, softwoods, and even some metals.
Stellite is a high-performance alloy that is used to create exceptionally durable saw blades. Stellite-tipped blades offer superior resistance to wear and heat, making them ideal for heavy-duty cutting tasks and challenging materials.
Apart from the materials themselves, blade coatings can also enhance the blade’s performance and longevity. Non-stick coatings, such as Teflon or industrial-grade coatings, reduce friction and prevent pitch and resin buildup on the blade, resulting in smoother cuts and easier blade maintenance.
