Abstract
A nosepiece assembly includes a first nosepiece portion including a fastener guide. The fastener guide has a support ledge to position a first fastener of a collated strip of fasteners in a drive channel. The nosepiece assembly also includes a second nosepiece portion connected to the first nosepiece portion opposite to the fastener guide with the first and second nosepiece portions defining the drive channel therebetween and defining a debris ejection passage therebetween. The debris ejection passage extends between the drive channel and a debris ejection aperture on an exterior surface of the nosepiece assembly.

A nosepiece assembly comprising:
- a first nosepiece portion including a fastener guide, the fastener guide having a support ledge to position a first fastener of a collated strip of fasteners in a drive channel;
- and
- a second nosepiece portion connected to the first nosepiece portion opposite to the fastener guide with the first and second nosepiece portions defining the drive channel therebetween and defining a debris ejection passage therebetween, the debris ejection passage extending between the drive channel and a debris ejection aperture on an exterior surface of the nosepiece assembly.
A powered fastening device nosepiece assembly comprising a drive channel defined by a first nosepiece portion and a second nosepiece portion, the drive channel extending longitudinally between the first nosepiece portion and the second nosepiece portion and being adapted to receive a drive blade that moves longitudinally in the drive channel toward a nose to cause a first fastener of a collated strip of fasteners to be driven from the nose and into a workpiece,
- wherein the first nosepiece portion and the second nosepiece portion define a debris ejection passage that is in communication with the drive channel and positioned outward therefrom such that debris located in the drive channel exits from the nosepiece assembly in a direction outward from the drive channel through the debris ejection passage.
