- Cutting through dense materials can increase power consumption as the saw motor works harder to overcome the resistance.
Cutting depth
The cutting depth, or the thickness of the cut material, impacts the load on the circular saw. Cutting deeper into a workpiece requires the saw to exert more power to drive the blade through the material.
Increasing the cutting depth can lead to higher power consumption due to the increased resistance encountered by the blade.
Blade condition and sharpness
The condition and sharpness of the circular saw blade affect its cutting efficiency and, subsequently, the power consumption.
A dull or damaged blade increases friction, requiring the motor to work harder to maintain cutting performance. This can result in higher power consumption than a sharp and well-maintained blade.
