How to Sharpen Circular Steel Saw Blades

Over time, circular saws will wear down and need to be removed and sharpened. Using a dull circular saw blade will increase the time it takes to accomplish a task, as well as risk damage to the saw. The materials necessary to sharpen a circular saw are available at home improvement stores. Once you have sharpened the circular saw blade, reattach it carefully. The saw will be razor-sharp and it will be much easier to cut or injure yourself.

Things You'll Need

• Wrench
• Single-sided saw sharpener

Instructions

1. Unscrew the circular saw blade, using the wrench to remove the bolts holding it in place.

2. Run the sharpener in a smooth motion back and forth against once of the blade teeth, keeping the diamond surface flat against the inner face of the saw tooth. Mark the sawtooth with chalk when you are finished so you will know your stopping point.

3. Sharpen the rest of the saw blade teeth, making sure they are all sharpened to the same specifications so that the blade will function smoothly. When all the teeth are sharpened to a satisfactory level, reattach the blade to the circular saw.
