3M 340D 60 grit sanding belt is a general purpose portable sanding belt that uses aluminum oxide abrasive on an X-weight cloth backing. This 3 inch x 21 inch size works on portable belt sanders for everyday sanding jobs where a belt-style abrasive is needed. The 340D version is an open coat belt, so abrasive grains are spaced to promote a good cut with less loading when sanding. That open coat construction lets dust clear more easily, which helps the belt maintain its cutting action across more of the work. As a general purpose abrasive belt in the 3M 340D and 341D family, this 60 grit option fits tasks that call for a relatively coarse cut on wood or similar materials in industrial and occupational settings.
This 3M 340D portable sanding belt is sized at 3 inch x 21 inch, so it is designed for use on portable belt sanders built around that belt length and width. The X-weight cloth backing supports the tension typical of portable belt sander tracking systems, helping the belt stay stable as it runs over contact wheels and platen areas. Because the belt is a general purpose portable sanding belt in the 340D and 341D family, its construction is oriented toward the demands of handheld belt sanding workflows in industrial and occupational environments.

The 340D sanding belt is described as an open coat belt that provides a good cut with less loading, so its abrasive grain pattern is intentionally spaced to help keep debris from compacting between grains.

The 340D belt line is available in 50 to 120 grit, and this belt uses 60 grit, placing it toward the coarse end of that range for more aggressive material removal compared with finer options. The combination of aluminum oxide abrasive, X-weight cloth backing, and open coat construction positions this belt as an excellent all-around abrasive belt for everyday use where portable sanding is part of the workflow.
