The nose piece guides fasteners or workpieces during operation and is subject to regular wear under production use.

Licensed technicians and tool-repair shops typically source this part for in-shop or on-site rebuilds.
This nose component is intended for use with the DEWALT MIII S4 platform. It is a common service part in production assembly environments, manufacturing facilities, and contractor settings where DEWALT power tools are operated at high cycle counts. Replacement of this part is typically performed as part of a scheduled maintenance interval or following inspection that reveals wear, cracking, or dimensional loss at the tool nose.
Designed as an OEM replacement nose component for the DEWALT MIII S4 tool platform. Confirm tool model and configuration against the DEWALT parts diagram before ordering.
