3M 7100099418 Trizact 217EA Abrasive Belt 132x4 Inch Ao

Product Description

The 3M 7100099418 is a Trizact 217EA coated abrasive belt designed for intermediate finishing and fine polishing on metal and other hard surfaces. It uses proprietary microreplication technology in which micron-graded aluminum oxide particles are formed into three-dimensional pyramids and bonded to a JE-weight rayon cloth backing. As the pyramids wear, fresh, sharp mineral is continuously exposed, delivering a consistent cut rate and predictable surface finish throughout the belt's service life. The belt measures 132 inches in length and 4 inches in width and is handled by metal finishing professionals and robotic grinding system operators.

This belt is suited for intermediate finishing steps prior to plating, buffing, or final polishing on ferrous and non-ferrous metal workpieces. The flexible JE-weight rayon backing conforms to contoured and irregular surfaces, making it effective in both manual and automated finishing lines. A built-in grinding aid helps dissipate heat during use, reducing the risk of heat-related warping or surface discoloration on temperature-sensitive parts. The belt is well matched to low-pressure applications where controlled, repeatable finishes are required.

Key Features

• Microreplicated aluminum oxide pyramids continuously expose fresh mineral as they wear, maintaining consistent cut throughout belt life
• JE-weight rayon cloth backing flexes over contoured surfaces for uniform contact and finish
• Grinding aid reduces heat buildup, helping prevent warping and discoloration of workpieces
• Produces finer surface finishes than conventional coated abrasive belts
• Engineered for stability and consistency in robotic and automated finishing applications
• Designed for light-pressure use to allow controlled abrasive breakdown and repeatable results

Compatibility

Designed for use on standard belt finishing machines and robotic grinding systems accepting 132-inch by 4-inch abrasive belts. Suitable for metal finishing operations including pre-plate, pre-buff, and fine polishing stages.

Installation Notes

Installation should be performed by a qualified machine operator or finishing technician familiar with belt grinder safety procedures. Power down and lock out the machine before mounting or removing the belt. Verify belt tracking and tension according to the equipment manufacturer's guidelines before resuming operation. Inspect the belt for tears or edge damage before each use.
