3M 7100179101 Abrasive Belt 132x1.25 Inch Ao Cloth

Product Description

The 3M 7100179101 is an aluminum oxide cloth abrasive belt engineered for low-pressure grinding and finishing applications on soft metals. Built on the Trizact 327DC platform, it uses a uniform brick-and-channel mineral structure that delivers consistent cut rate and finish quality from the first use through the end of belt life. The open channel geometry clears swarf and reduces loading, which is a common problem when working soft metals with conventional belts. A built-in grinding aid keeps the workpiece cool during extended runs. This belt suits fabrication shops, metalworking operations, and production finishing lines where consistent surface quality and belt longevity are priorities.

The 327DC belt is designed for intermediate scratch refinement, dimensional finishing, and minor mill line and scale removal on soft metals such as aluminum, copper, and brass. It performs well in low-pressure applications where standard abrasive belts glaze or load prematurely. Typical install scenarios include wide belt sanders, narrow contact-wheel grinders, and surface conditioning machines used in metal fabrication and finishing environments. The belt measures 132 inches in length and 1.25 inches in width.

Key Features

• Uniform brick-like aluminum oxide structure provides consistent cut and finish from start to end of belt life
• Brick-and-channel mineral geometry channels swarf away and resists loading on soft metals
• Grinding aid integrated into the abrasive structure reduces heat buildup at the workpiece
• Sustained cut rate in low-pressure applications reduces the need for additional process steps
• Extended belt life compared to conventional abrasive belts, reducing per-part abrasive cost
• Cloth backing provides flexibility and durability for contoured and flat surface work

Compatibility

Designed as a finishing and refinement belt for belt sanders and grinding machines accepting a 132-inch by 1.25-inch abrasive belt. Well suited for soft metal applications including aluminum, copper, and brass where low-pressure contact and loading resistance are required.

Installation Notes

Belt installation and replacement should be performed by a qualified operator with the machine de-energized and locked out per applicable OSHA lockout/tagout procedures. Verify belt tracking and tension according to the machine manufacturer specifications before resuming operation. Inspect the belt splice and backing for damage before mounting. Do not exceed the machine's rated belt speed for the belt width and length in use.
