Plywood is a versatile and widely used material in the construction and woodworking industry. However, cutting it can be a challenging task, especially if you do not know how to do it properly. One of the most common problems that people encounter when cutting plywood is splintering. This is when the edges of the plywood break off, leaving a rough and uneven surface. In this article, we will discuss how you can cut plywood without splintering the edges.
1. Use the right saw
The type of saw you use can greatly affect the quality of your cut. A circular saw with a fine-toothed blade is ideal for cutting plywood. The blade should have at least 40 teeth for a smooth cut. A jigsaw or a reciprocating saw can also be used, but they tend to produce rougher edges. A table saw is not recommended for cutting plywood as it can cause tear-out.
2. Mark your cut line
Before you start cutting, make sure to mark your cut line. Use a straight edge or a square to ensure a straight and accurate cut. You can also use masking tape along the cut line to reduce splintering.
3. Cut with the good side down
When cutting plywood, always place the good side down. This is the side that will be visible once the project is finished. By placing the good side down, any splintering will occur on the backside of the plywood, which will not be visible.
4. Support the plywood
Support the plywood on both sides of the cut line to prevent it from splintering. This can be done by using sawhorses or clamping the plywood to a workbench. Make sure that the plywood is fully supported and does not move during the cutting process.
5. Cut at a slow speed
Cutting too fast can cause the blade to heat up and melt the glue holding the layers of the plywood together. This can cause splintering and a rough cut. To prevent this, cut at a slow and steady speed. This will also give you more control over the saw and produce a smoother cut.
6. Use a zero-clearance insert
A zero-clearance insert is a thin piece of material that is placed around the blade of a saw. It helps to prevent tear-out and splintering by supporting the plywood fibers as they are cut. You can purchase a zero-clearance insert or make one yourself using a piece of plywood.
7. Use a sharp blade
Using a dull blade can cause splintering and tear-out. Make sure to use a sharp blade that is designed for cutting plywood. If the blade is dull, replace it before attempting to cut the plywood.
Conclusion
Cutting plywood without splintering the edges requires the right tools and techniques. By using a circular saw with a fine-toothed blade, marking your cut line, cutting with the good side down, supporting the plywood, cutting at a slow speed, using a zero-clearance insert, and using a sharp blade, you can achieve a smooth and clean cut. By following these tips, you will be able to cut plywood with confidence and precision.

Frequently Asked Questions
1. What are the best tools to use for cutting plywood?
There are several tools that can be used to cut plywood without splintering the edges. These include a circular saw with a fine-tooth blade, a jigsaw with a down-cutting blade, and a track saw.
2. How do I prevent splintering when using a circular saw?
To prevent splintering when using a circular saw, you can use a guide or a straight edge to help keep the saw blade in a straight line. You can also use masking tape or painter’s tape along the cut line to help prevent splintering.
3. How do I prevent splintering when using a jigsaw?
To prevent splintering when using a jigsaw, use a down-cutting blade, which cuts on the downstroke, reducing the likelihood of splintering. You can also use a guide or a straight edge to help keep the saw blade in a straight line.
4. How do I prevent splintering when using a track saw?
To prevent splintering when using a track saw, use a fine-tooth blade and make sure the saw blade is sharp. You can also use a guide or a straight edge to help keep the saw blade in a straight line.
