3M 7100305427 Hook Loop Disc 5 in 120 Grit Aluminum Oxide

Product Description

The 3M 7100305427 is a 5-inch hook and loop abrasive disc designed for surface finishing, sanding, and preparation work across a wide range of trade and light industrial applications. Built on a flexible film and polyester backing, this disc conforms to contoured surfaces and delivers consistent material removal with its aluminum oxide abrasive at 120 grit (fine grade). The hook and loop attachment system allows for fast disc changes without tools, reducing downtime during extended use. This disc belongs to the 3M 375L series, which is engineered for durability and consistent cut performance on wood, composites, and painted surfaces.

This disc is suited for finishing and prep work in woodworking, construction trades, and surface restoration. The fine 120-grit rating makes it appropriate for intermediate to final sanding passes where a smooth surface is the goal before painting, sealing, or coating. The flexible backing helps the disc maintain contact on irregular or curved surfaces. No vacuum holes are included in this disc, so it is intended for use with sanders that do not require dust extraction through the disc face. Sold individually, with a minimum order quantity of 250 units.

Installation Notes

Align the disc flat against the hook and loop pad and press firmly to seat before operating the tool.

Proper eye and respiratory protection should be worn during sanding operations.
