Do You Finish Side Up Or Down When Cutting With Circular Saw?

When it comes to using a circular saw, there are certain techniques and practices that are important to follow in order to achieve the best results. One of the questions that often arises is whether to finish the cut with the blade side up or down. There are a few factors to consider when making this decision.

The Importance of the Finish Cut

The finish cut is the final cut that is made in a piece of wood or other material. It is the cut that determines the final dimensions and appearance of the piece. A clean and precise finish cut is essential for achieving a professional-looking result.

Blade Side Up or Down?

When making a finish cut with a circular saw, the blade can be positioned either with the teeth facing up or down. There are arguments for both methods, and ultimately the decision will depend on personal preference and the type of material being cut.

Blade Side Up

One argument for finishing the cut with the blade side up is that it can help to prevent tear-out. Tear-out occurs when the fibers of the wood or other material are pulled away from the surface, resulting in a rough and uneven finish. This is particularly common when cutting with the grain of the wood. By finishing the cut with the blade side up, the teeth of the saw are pulling the fibers down as they cut, which can help to reduce tear-out.

Another argument for finishing the cut with the blade side up is that it can help to prevent splintering. Splintering occurs when the wood or other material splits along the grain as it is being cut. By finishing the cut with the blade side up, the teeth of the saw are pushing down on the fibers as they cut, which can help to prevent splintering.

Blade Side Down

One argument for finishing the cut with the blade side down is that it can help to achieve a cleaner and smoother finish. When the blade is positioned with the teeth facing down, the saw is cutting through the material from the top down, which can result in a cleaner and smoother cut. This can be particularly important when working with materials that are prone to tear-out, such as plywood or particleboard.

Another argument for finishing the cut with the blade side down is that it can help to reduce the risk of kickback. Kickback occurs when the saw blade catches on the material and is thrown back towards the user. This can be a dangerous situation, and finishing the cut with the blade side down can help to reduce the risk of kickback.

Conclusion

Ultimately, the decision of whether to finish the cut with the blade side up or down will depend on personal preference and the type of material being cut. It is important to consider the factors outlined above and to take the necessary precautions to ensure a safe and successful cut.
