Abstract: An assembly includes a cut-off tool and a shroud. The cut-off tool including a motor housing, a pistol-grip handle, an arbor, a cutting disk attachable to the arbor and rotatable about a cutting disk axis, and a guard. The shroud being coupled with the guard and including a shoe configured to support the shroud on a workpiece, a periphery of the shoe defining a shoe profile in a frame of reference parallel with the workpiece with the shoe supported on the workpiece, a depth adjustment bracket coupled to the shoe, a shroud body engageable with and surrounding the guard, the shroud body being pivotably coupled to the shoe to adjust a cut depth of the cutting disk below the shoe, and a lever arm extending between the shroud body and the depth adjustment bracket. The lever arm and the depth adjustment bracket are positioned entirely within the shoe profile.

Abstract: A powered fastener driver including a housing defining a cylinder support portion with a cylinder and a motor housing portion. The driver includes a piston and a driver blade. The piston is movable within the cylinder from a top-dead-center (TDC) position to a bottom-dead-center (BDC) position with a blade attached thereto for driving a fastener. The driver includes a lifter for moving the piston and blade, in unison, from the BDC position toward the TDC position. The driver includes a nosepiece from which the fastener is discharged, a motor disposed in the motor housing portion, a fan coupled to the motor to receive torque therefrom, causing the fan to generate an airflow, and a conduit for directing the airflow to at least one of away from the cylinder to clear and/or prevent debris accumulated in the cylinder support portion of the housing, or toward the cylinder for cooling the cylinder.
