Understanding Table Saw Blades

A. Types of Table Saw Blades

When it comes to table saw blades, not all are created equal. Each type serves a specific purpose in the realm of woodworking.

1. Rip-Cut Blades: Designed for cutting along the grain of the wood, these blades have fewer teeth and make quick work of straight-line cuts.
2. Cross-Cut Blades: For cutting across the grain, cross-cut blades have more teeth with an alternate top bevel (ATB) configuration, resulting in smoother, splinter-free cuts.
3. Combination Blades: As the name suggests, these blades offer versatility. They can handle both rip cuts and crosscuts reasonably well, making them a popular choice for general woodworking.
4. Dado Blades: Perfect for creating dadoes, rabbets, and grooves, dado blades consist of two outer blades and multiple chippers. They allow for precise and wide cuts.

B. Blade Tooth Configuration

1. Flat Top Grind (FTG): FTG blades have flat, square teeth, making them ideal for rip cuts. They excel at quickly removing material along the grain.
2. Alternate Top Bevel (ATB): ATB blades have angled teeth that alternate between left and right. This configuration is excellent for cross-cutting, leaving clean edges.
3. Triple Chip Grind (TCG): TCG blades combine flat teeth with beveled teeth. They’re suitable for cutting hard and abrasive materials like laminates or metals.

C. Blade Materials

1. Carbide-Tipped Blades: Known for their durability and sharpness, carbide-tipped blades feature carbide teeth that can withstand a lot of wear and tear, making them suitable for demanding projects.
2. High-Speed Steel (HSS) Blades: HSS blades are budget-friendly and offer decent performance. They’re great for occasional woodworkers who don’t require premium results.
3. Diamond-Tipped Blades: These blades are designed for cutting hard materials like ceramics or glass. They utilize industrial-grade diamonds for exceptional longevity.

D. Blade Sizes and Compatibility

Blade size matters. It’s crucial to ensure your chosen blade size matches your table saw’s specifications. Most common sizes range from 7 ¼ inches to 12 inches in diameter. Always check your table saw’s manual for compatibility, as using the wrong size can lead to safety hazards and poor results.
