3M 7100179116 Abrasive Belt P400 Grit 128x52.5 Inch Ao

Product Description

The 3M 7100179116 is a coated abrasive belt designed for sanding and finishing flat surfaces in woodworking applications. Built on a heavy F-weight paper backing, this belt uses a closed-coat aluminum oxide mineral to deliver aggressive cut and consistent finish quality across hardwoods and similar materials. The anti-static treatment reduces dust buildup and resists loading, extending usable belt life. A film media splice keeps the joint strong and allows smooth running in either direction. Licensed HVAC, plumbing, and woodworking trade shops alike rely on this belt format for wide-surface finishing passes on production or bench equipment.

This belt is sized at 128 inches in length and 52.5 inches in width, making it suited for wide-belt sanding machines used in cabinet shops, millwork facilities, and industrial woodworking operations. The P400 grit rating positions it for finish sanding stages where surface smoothness is the priority. The closed-coat construction provides greater grain density than open-coat alternatives, resulting in finer surface finishes on hardwood species. It is sold individually and intended for professional woodworking and finishing environments.

Installation Notes

Belt installation should be performed by a qualified operator with the machine powered down and locked out per applicable safety procedures. Verify belt tracking and tension settings per the sander manufacturer guidelines before resuming operation. Inspect the splice and belt surface for damage before each use. Do not exceed the machine-rated speed for the belt width and length.
