The 3M 7010362549 is a replacement coupler designed for use with select 3M extended pneumatic abrasive tools. The coupler serves as a mechanical connection component within the tool assembly, transmitting rotational force between internal drive components. This part is sold individually and is intended for service-level repairs performed by trained technicians working in fabrication, metalworking, automotive body, or industrial finishing environments. Referencing the owner's manual parts list and schematic before ordering or installing is strongly recommended to confirm correct fitment and placement within the tool.
This coupler is a direct replacement component for the 3M Extended Disc Sander (PN 28622), the Extended T-27 Grinder (PN 28413), the Extended T-27 Grinder (PN 28414), and the Extended COW Tool (PN 28407). These tools are commonly used in production line and shop environments where extended-reach grinding and disc sanding operations are required. Replacing worn or damaged couplers restores proper drive engagement and helps maintain consistent tool performance.
Confirmed compatible with the 3M Extended Disc Sander (PN 28622), Extended T-27 Grinder (PN 28413), Extended T-27 Grinder (PN 28414), and Extended COW Tool (PN 28407). Refer to the owner's manual parts list for verification before installation.
Installation of this coupler should be performed by a qualified technician familiar with pneumatic tool repair. Disconnect the tool from its air supply before disassembly. Consult the 3M owner's manual schematic to identify the coupler's location within the drive assembly and follow the documented service procedure. Do not force components during reassembly, as improper alignment can damage internal drive parts.
