Why does my circular saw blade stop spinning?

The most common reason your circular saw blade stops spinning is because your workpiece is pinching the blade. This can also cause the blade to kickback.

To prevent this from happening you need to support your workpiece properly to allow it to set securely through the entire cut.

When making a crosscut this rarely happens because the cut is so quick, but when you are ripping through a long and wide workpiece this is more likely the cause of your to blade stop spinning.

Lay your workpiece on scrap blocks, on sacrificial boards, or hang it off your cutting surface if cutting the edge piece away.

Other reasons your circular saw blade could be stop spinning are your blade isn’t deep enough, your blade is dull (Very Common), loose clutch bolt, dead battery, power cable issue or motor issue.

I will always have a special place in my heart for woodworking. I have such fond memories working on projects with my parents on the weekends in the garage growing up. We built tables, shelves, a backyard shed, 10' base for a water slide into the pool, 2 story fort playhouse with a fire pole, and so much more. This woodworking blog allows me to write helpful articles so others can enjoy woodworking as much as we have.
