3M 7100019320 5 Inch Silicon Carbide Psa Abrasive Disc Roll

Product Description

The 3M 7100019320 is a non-woven abrasive disc roll designed for wet or dry finishing and polishing of contoured surfaces. Silicon carbide particles are precision-coated onto a flexible nonwoven backing, delivering a uniform, consistent finish on softer materials including plastics, aluminum, brass, and copper. Available in 15.0 and 30.0 micron grades, the color-coded system makes grade selection straightforward on the job. The pressure-sensitive adhesive (PSA) backing allows quick disc mounting and removal. This roll format reduces hand sanding and buffing time and cuts down the total number of finishing steps required.

This abrasive disc roll is suited for finishing and polishing applications in fabrication, metalworking, and light manufacturing environments. It performs on contoured and flat surfaces alike, making it a practical choice for technicians and tradespeople working with aluminum, brass, copper, and plastic components. The wet or dry capability allows use with water or cutting fluid to control swarf and improve surface clarity during fine finishing operations.

Key Features

• Silicon carbide abrasive on a flexible nonwoven backing for consistent surface finish
• Precision micron coating delivers uniform, repeatable results across the work surface
• Wet or dry use compatible with water or cutting fluids
• PSA backing for fast disc mounting and removal
• Color-coded micron grading simplifies grade identification
• Reduces finishing steps and total hand sanding time

Compatibility

Designed for use on softer materials including plastics, aluminum, brass, and copper; compatible with standard 5 inch PSA disc backing pads.

Installation Notes

This abrasive disc roll is typically applied by fabricators, machinists, or finishing technicians using a compatible 5 inch PSA backing pad. Ensure the backing pad surface is clean and free of debris before mounting a disc to ensure full adhesive contact. When used wet, keep sanding fluids away from power tool motors and electrical components. Dispose of used abrasive discs in accordance with local regulations, particularly when residue contains metal particulates.
