Inner Blade Flange
The inner flange provides the reference plane for the blade; if it is warped or has captured debris, the blade cannot sit flush. Forensic inspection often reveals compression scoring or warping after a blade-pinch or kickback event, which translates to significant tip-wobble on a 12-inch diameter blade.

Outer Blade Flange
The outer flange (blade clamp) must apply even pressure across the blade's plate. If the flange has become cupped or the arbor bolt has been over-torqued, it can distort the blade plate during the clamping phase, inducing a wobble that is not present when the blade is loose.

Spindle and Gear Assembly
If replacing flanges does not resolve the run-out, the spindle shaft itself has likely suffered plastic deformation. This assembly includes the output shaft and the bearing interface; a bend of only a few thousandths of an inch at the spindle will cause a visible 1/8-inch wobble at the blade teeth.
