What types of blades are compatible with the DeWalt DCS391?
The DeWalt DCS391 circular saw is compatible with a variety of 6.5-inch blades, including general-purpose blades, ripping blades, and crosscut blades. General-purpose blades are ideal for making straight cuts in various materials, while ripping blades are designed for making cuts with the grain in wood. Crosscut blades, on the other hand, are optimized for making cuts across the grain in wood and are often used for finer cuts and more precise applications.
When selecting a blade for the DeWalt DCS391, it is essential to consider the specific cutting task at hand and choose a blade that is designed for that purpose. DeWalt offers a range of 6.5-inch blades that are specifically designed for use with the DCS391, including blades with different tooth counts, kerf sizes, and coating options. Additionally, many third-party manufacturers also offer compatible blades that can be used with the DeWalt DCS391, providing users with a wide range of options to suit their specific needs and preferences.
Can I use a larger or smaller blade on the DeWalt DCS391?
While the DeWalt DCS391 is designed to use 6.5-inch blades, some users may wonder if they can use larger or smaller blades on the saw. In general, it is not recommended to use a larger blade on the DeWalt DCS391, as this can put excessive strain on the saw’s motor and gearbox, potentially leading to premature wear and reduced performance. Additionally, using a larger blade may also affect the saw’s balance and stability, making it more difficult to control.
Using a smaller blade on the DeWalt DCS391 is also not recommended, as this can reduce the saw’s cutting capacity and effectiveness. However, some users may choose to use a smaller blade in specific situations, such as when making precise cuts in thin materials or when working in tight spaces. If you do choose to use a smaller blade on the DeWalt DCS391, be sure to follow the manufacturer’s guidelines and take necessary safety precautions to avoid accidents and ensure optimal performance.
How do I change the blade on the DeWalt DCS391?
Changing the blade on the DeWalt DCS391 is a relatively straightforward process that can be completed in a few minutes. To change the blade, first, ensure the saw is unplugged and the battery is removed. Next, locate the spindle lock button, which is typically located on the top of the saw, and press it to lock the spindle in place. Then, use a wrench or Allen key to loosen the blade nut by turning it counterclockwise.
Once the blade nut is loose, carefully pull the old blade off the spindle and discard it. Take the new blade and align it with the spindle, ensuring the teeth are facing the correct direction. Place the new blade onto the spindle and hand-tighten the blade nut. Finally, use a wrench or Allen key to tighten the blade nut in a clockwise direction, ensuring it is securely fastened. Be sure to follow the manufacturer’s guidelines and take necessary safety precautions when changing the blade to avoid accidents and ensure optimal performance.
What is the kerf size of the DeWalt DCS391 blade?
The kerf size of the DeWalt DCS391 blade refers to the thickness of the blade itself, which can affect the width of the cut and the amount of material removed. The kerf size of a standard 6.5-inch blade for the DeWalt DCS391 is typically around 0.059 inches, although some blades may have a slightly larger or smaller kerf size. A thinner kerf size can be beneficial for making precise cuts and reducing material waste, while a thicker kerf size can provide more aggressive cutting and faster material removal.
When selecting a blade for the DeWalt DCS391, it is essential to consider the kerf size and how it will affect your specific cutting applications. For example, if you are making cuts in thin materials or require precise control, a blade with a thinner kerf size may be a better choice.
