Abstract: A rotary hammer includes a housing, a first motor supported by the housing and defining a first motor axis, a second motor supported by the housing and defining a second motor axis that is coaxial with the first motor axis, and a spindle coupled to the first motor for receiving torque from the first motor, causing the spindle to rotate. The rotary hammer further includes a reciprocation mechanism operable to create a variable pressure air spring within the spindle. The reciprocation mechanism includes a piston configured to reciprocate within the spindle in response to receiving torque from the second motor, a striker that is selectively reciprocable within the spindle in response to reciprocation of the piston, and an anvil that is impacted by the striker when the striker reciprocates towards the tool bit. The anvil imparts axial impacts to the tool bit.

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 position and the release position in response to pivoting movement of the handle.

Abstract: A miter saw includes a base assembly and a saw unit pivotably coupled to the base assembly. The saw unit includes a saw arm, a brushless motor supported by the saw arm, and power electronics positioned outside the motor for supplying power to the motor. The power electronics are coupled to a structural component of the miter saw to utilize the entire mass of the structural component as a heat sink to dissipate heat generated by the power electronics.
