3M 7000119275 Abrasive Disc 320 Grit 8 Inch

Product Description

The 3M 7000119275 is a silicon carbide abrasive disc in the Wetordry 481W series, engineered for surface finishing and paint preparation on metal and wood substrates. The disc measures 8 inches in diameter and cuts at 320 grit, delivering a consistent scratch pattern suited for final prep work before coating or painting. The water-resistant polyester backing allows the disc to run wet or dry, giving the operator flexibility depending on the application and workpiece material. It is used by metal fabricators, body shop technicians, woodworkers, and maintenance professionals who need a reliable abrasive for controlled stock removal without heavy manual pressure.

This disc is suited for use on metals, hardwoods, and other solid substrates where surface conditioning, coating removal, or paint prep is required. The 320 grit silicon carbide mineral cuts consistently and leaves a uniform scratch pattern, making it appropriate as a finishing step prior to priming or topcoating. The wet-or-dry capability makes it a practical alternative to compound-and-lubricant finishing methods in both shop and field settings.

Key Features

• 320 grit silicon carbide mineral for fast, consistent cutting with a uniform scratch pattern
• 8-inch diameter disc suits standard disc sanders and backing pads of that size
• Water-resistant polyester backing allows wet or dry operation
• Effective for paint prep, coating removal, and surface conditioning on metals and hardwoods
• Reduces need for heavy manual pressure during finishing passes
• Serves as a practical alternative to compound and lubricant-based finishing methods

Compatibility

Designed for use with standard 8-inch disc sanding tools and backing pads that accept hook-and-loop or plain abrasive discs of that diameter.

Installation Notes

This abrasive disc is installed and used by metal fabrication technicians, body shop professionals, and woodworking tradespeople. Secure the disc firmly to the backing pad before operation and confirm the backing pad diameter matches the disc. When running wet, ensure the tool is rated for wet use and that water or coolant does not contact electrical components. Inspect the disc for tears or wear before each use and replace if the abrasive surface is loaded or degraded.
