Whether you’re crafting or building, your project's success depends on the efficiency of your hand tools. Many people use circular saws to slice through lumber, but the blade can become too dull to effectively cut and shape wood. Here are some ways to know when it’s time to sharpen your blades. 

How to Identify a Dull Circular Saw Blade

1. Strained Motor Sounds

When this hand tool is sharp, it effortlessly slices through the wood and doesn’t overwork the motor. However, a dull blade requires additional horsepower to cut through the workpiece. This added stress on the motor usually produces a louder sound from the equipment.

2. Blade Chips Wood

A sharpened circular saw blade should cut through wood without chipping away at the lumber. When slicing lumber against its grain with a faulty blade, the hand tool will lift small pieces of the material along its edge. Poorly positioning the workpiece or using a dull blade can result in chipped wood, so make sure you are cutting the wood correctly before sharpening the tool. 

3. Visible Deterioration 

It would be best if you inspected your equipment regularly to ensure it has no damage. If you notice rounded edges or chipped teeth on your saw blade, it needs to be replaced or sharpened. Neglecting to examine your equipment and take immediate action against deterioration will make the blade duller and degrade future cuts.

4. Circular Blade Smokes

Since dull blades cannot efficiently saw through lumber, the metal may create friction as it spins against the material. The friction causes the wood to overheat, and it produces a smell similar to burnt toast. The saw may also make visible white smoke. Using the circular saw with a dull blade could lead to dark burn spots on the workpiece.
