Circular Saw Excessive Wood Splintering

Splintering, or tear-out, occurs when wood fibers are pulled or broken rather than cleanly sliced. To confirm this symptom, inspect the underside of the workpiece along the entire length of the cut. If the wood fibers are raised, jagged, or missing in a way that creates a rough texture at the point of blade exit, the saw is causing tear-out. Note that standard circular saw blades rotate upward, making the bottom face the primary area for splintering observation.
