FEIN Weldon 3/4 Adapter

This FEIN adapter connects tools with a Weldon 3/4 inch shank to compatible drives. It is built for professional metalworking where secure tool holding matters. The part number 63901078010 identifies the exact component for reordering. Supplied new and shipped directly from the manufacturer.

For metalworkers using FEIN magnetic drills
