3M 7100106789 Inline Sander 1 Hp 5/8-11 External Shaft

Product Description

The 3M 7100106789 is a 1 HP inline sander designed to generate straight-line scratch patterns for finishing stainless steel and other metals. Built around a 5/8-11 external shaft, this tool accepts rubber slotted expander wheels and 3M coated abrasive or surface conditioning belts, making it a purpose-built solution for consistent, repeatable linear finishes on metal surfaces. It is well-suited for fabrication shops, food equipment manufacturing, and any trade environment where controlled surface conditioning of metal is required.

This inline sander is intended for use in metalworking and fabrication applications where straight-line scratch finishes are specified on stainless steel or similar metals. It is designed to work with rubber slotted expander wheels (PN28348 or PN28349) and 3M Coated Abrasive Belts sized 3-1/2 inches x 15-1/2 inches, or 3M Surface Conditioning Belts sized 3 inches x 10-11/16 inches. The 3 Wheel Adaptor Kit PN45038 is required to mount the wheel to the inline sander.
