Abstract: A table saw includes a table, a saw unit movably coupled underneath the table, a riving knife extending through the table, and a quick-release assembly selectively coupling the riving knife to the table. The quick-release assembly includes a mounting plate coupled to the table and a clamping plate movable relative to the mounting plate between a clamping position, in which the riving knife is clamped between the mounting plate and the clamping plate to secure the riving knife to the table, and a release position, in which the riving knife is releasable from the table. The quick-release assembly further includes a pin coupled for movement with the clamping plate and a handle pivotably coupled to the pin. The pin has a cam portion engageable with the saw unit. The clamping plate is movable between the clamping positon and the release position in response to pivoting movement of the handle.

Abstract: An expansion tool includes a housing, a collar rotatably coupled to the housing, a plurality of jaws coupled for co-rotation with the collar, a mandrel movable relative to the housing between a retracted position and an extended position to expand the jaws, and a drive mechanism including a rotatable cam. Rotation of the cam moves the mandrel between the retracted position and the extended position. The expansion tool further includes an indexing gear configured to incrementally receive torque from the drive mechanism such that continuous rotation of the drive mechanism incrementally rotates the indexing gear, and a clutch assembly including a clutch gear meshed with the indexing gear, a clutch cover surrounding the clutch gear, and a plurality of rolling elements disposed between the clutch gear and the clutch cover. The clutch cover is drivably coupled to the collar such that rotation of the clutch cover rotates the collar.
