• Compound Cuts: This style combines both miter and bevel cuts, requiring a versatile tooth angle that can handle both aspects effectively for intricate designs.

Ripping cuts necessitate a tooth angle that allows for aggressive material removal, which is typically around 20 to 30 degrees. This steeper angle helps to clear chips efficiently and reduces the likelihood of the blade binding in the material.

Crosscutting, on the other hand, generally favors a tooth angle of about 0 to 10 degrees to create smoother edges and minimize splintering. A flatter tooth angle allows the blade to slice through the wood fibers cleanly, resulting in a neater finish.

Miter cuts require a precise tooth angle that aligns with the desired angle of the cut, often around 30 degrees for many applications. The correct angle ensures a smooth and tight fit at the joint, which is crucial for aesthetic and structural integrity.

Bevel cuts typically use a tooth angle similar to that of crosscutting but can vary based on the specific angle of the bevel, often requiring adjustments to prevent tear-out on the surface. A careful balance of the tooth angle helps maintain the quality of the cut while accommodating the tilt of the saw.

For compound cuts, the ideal tooth angle needs to address both the miter and bevel aspects, which can complicate the selection. This often results in a compromise tooth angle that provides versatility and allows for clean cuts across both dimensions, making it essential for detailed woodworking projects.
