Why Blade Problems In Dewalt Circular Saw 20V?

Various factors can cause blade problems in a circular saw.

  • Dull blade: The most apparent reason a saw blade underperforms is that it has become dull over time. When the teeth on the saw blade become dull, they cannot cut through the material smoothly, and the saw blade may tend to slip or drag.
  • Blade not correctly mounted: If the saw blade is not mounted correctly, the blade’s teeth cannot cut through the material properly. The result is often poor or uneven cuts.
  • Wrong blade for the material: Different materials require different saw blades, and using the wrong blade can cause all sorts of problems. For example, using a fine-tooth blade on a larger piece of wood or plywood can result in scorch marks and splintering.

Tips To Enhance Blade Performance

The following tips will help you enhance your Dewalt circular saw 20v blade’s performance and prolong its life:

  • Use the right blade: Choosing the right saw blade for the job is essential. Avoid using a blade that is too small or large or has the wrong tooth configuration.
  • Always keep the blade clean: Sawdust and debris can accumulate on the blade, causing it to lose its sharpness. Clean the blade after each use. A clean blade will make smoother and faster cuts, extending the life of the blade.
  • Use a blade lubricant: A blade lubricant will reduce friction and heat, which can prolong blade life. You can buy a lubricant or make your own by mixing equal parts of water and detergent.
  • Store the blade correctly: When not used, store your saw blade in a dry area free of dust and debris. You can store them in a blade case or cabinet to protect them from damage.
  • Sharpen the blade regularly: Regular maintenance and sharpening will extend your blade’s life. You can either sharpen the blades yourself using a file or send them to be professionally sharpened.

Remembering the above tips, you can enhance your Dewalt circular saw 20v blade’s performance and make the most of your woodworking projects.
