Workshop Safety

Circular saw blades flex sideways under cutting load, creating wobble that causes the blade to rub kerf walls and generate binding conditions.

Blade guards are spring-loaded shields that retract during cutting and close when the saw withdraws. What guards protect against during kickback and why mechanical timing limits their effectiveness.

Blade binding occurs when wood pinches the spinning blade from both sides simultaneously, preventing forward cutting while the blade continues rotating at full speed. Understand the tooth-level mechanics that trigger violent kickback.

Gravity pulls unsupported wood downward during cutting, closing the kerf behind the blade and creating progressive pinching that leads to binding.

Circular saws kick back when blade binding creates rotational force that drives the saw toward the operator. The physics of pinching, blade deflection, and why unsupported wood causes violent reactions.
