As a professional handyman, I have seen many issues with circular saw blades. One of the most common issues that cause a cordless DeWalt circular saw to keep stopping is a dull or warped blade. A dull blade can cause poor cutting performance and can also be dangerous because it can cause kickback. A warped blade can cause the saw to stop in the middle of a cut.

To avoid these issues, it is important to ensure that the blade is sharp and in good condition before using it. If the blade is dull, it should be sharpened or replaced with a new blade. A sharp blade will provide a cleaner cut and will also reduce the risk of kickback. A new blade will provide the best performance and will also last longer than a dull blade.

Another issue that can cause a DeWalt cordless circular saw to stop is a blade guard that is not set correctly. The blade guard should be set so that it is not too close to the workpiece. If the blade guard is too close, it can cause the saw to stop in the middle of a cut.

The arbor of the saw should also be checked to make sure that it is clean and free from debris. A dirty arbor can cause the blade to wobble, which can cause the saw to stop in the middle of a cut.

Lastly, it is important to ensure that the blade is deep enough in the workpiece. If the blade is not deep enough, it can cause the saw to stop in the middle of a cut. The teeth of the blade should also be checked to make sure that they are not worn or damaged. Worn or damaged teeth can cause the saw to stop in the middle of a cut and can also cause poor cutting performance.

In summary, to avoid blade issues that can cause a DeWalt cordless circular saw to keep stopping, it is important to ensure that the blade is sharp, the blade guard is set correctly, the arbor is clean, the blade is deep enough in the workpiece, and the teeth are not worn or damaged.

Working with Different Materials

As a woodworker, I often work with different materials such as wood and metal. When using a cordless circular saw, it is important to know how to adjust the settings to work with different materials.

When working with wood, it is important to ensure that the workpiece is properly supported. One of the biggest reasons why a circular saw might stop in the middle of use is because the workpiece that you are trying to cut is not properly supported. This could cause the blade to bind, which could lead to the saw stopping.

When working with metal, it is important to use the appropriate blade. A metal cutting blade is designed to cut through metal, while a wood cutting blade is designed to cut through wood. If you use the wrong blade, you could damage the blade or the saw, and the saw could stop working.

Another important factor to consider when working with different materials is the speed of the saw. The speed of the saw should be adjusted based on the material being cut. For example, when cutting through thicker materials like hardwood, the saw should be set to a slower speed, while thinner materials like softwood can be cut at a faster speed.

In summary, when working with different materials, it is important to ensure that the workpiece is properly supported, use the appropriate blade, and adjust the speed of the saw based on the material being cut. By following these guidelines, you can ensure that your cordless circular saw continues to work properly and efficiently.
