The 3M 7010327095 is a left-hand thread bushing with a 3/8-inch NPT thread form, designed as a replacement component for 3M right-angle grinders and sanders. Thread bushings like this one serve as the interface between the tool spindle and grinding or sanding attachments, maintaining secure engagement during high-torque operation. This part is sold individually and is intended for installation by qualified tool service technicians or experienced trade professionals performing maintenance on compatible 3M power tools.
This bushing is a direct replacement component for 3M right-angle grinder and sander models. Refer to the applicable owner's manual parts list and tool schematic to confirm fitment before ordering. Left-hand thread orientation is standard for rotating tool spindle hardware, where the direction of rotation naturally tightens the attachment under load. Proper identification of the thread specification is critical before replacement to avoid damage to the tool spindle.
Designed as an OEM replacement bushing for 3M right-angle grinders and sanders. Consult the owner's manual parts list and tool schematic to verify this part number is correct for the specific tool model being serviced.
Installation should be performed by a qualified tool service technician familiar with power tool spindle components. Disconnect and de-energize the tool completely before beginning any disassembly or part replacement. Left-hand threads require counter-clockwise installation — confirm thread direction before applying force to avoid cross-threading or spindle damage. Refer to the 3M owner's manual for the specific tool model for the correct parts list and assembly sequence.
