Driver SA components serve as internal drive assemblies within power tool mechanisms, transmitting torque or motion between operating parts.

This part is suited for repair shops, field service technicians, and trade professionals who service DEWALT power tools at the component level. It is appropriate for scenarios where the original driver SA assembly has worn or failed and a like-for-like replacement is required to restore tool function. Specific system or model compatibility should be confirmed against the original tool documentation before ordering.
Designed as an OEM-style replacement Driver SA part for compatible DEWALT power tools. Verify compatibility with your specific tool model number using DEWALT parts documentation before installation.
