According to the American Furniture Manufacturers Association (AFMA), ripping blades are engineered for making long cuts in solid wood and engineered wood products. These blades reduce friction and tear out, resulting in cleaner cuts.
The effectiveness of a ripping blade on 2×4 cuts can be attributed to its tooth design and geometry. The large, flat teeth remove more material with each pass. This design results in less heat build-up and minimizes binding, making the process quicker and more efficient. Furthermore, the kerf, or the width of the cut made by the blade, is narrow, which means less waste.
Cutting along the grain, known as ripping, requires specialized blades to handle the orientation of the wood fibers effectively. For instance, a crosscut blade is less suited for this job as it has more teeth designed for cutting across the grain. This can lead to excessive tear-out and jagged edges in the cut.
Specific conditions that contribute to the effectiveness of ripping blades include the thickness of the material and the cutting speed. For best results, the cutting speed should match the material’s density and moisture content. For example, when cutting a dry 2×4, a ripping blade would slice through with minimal effort, while a wet or dense board may require slower speeds to prevent binding.
