3M 7000000743 Roloc Bristle Disc 80 Grit 2 Inches Yellow

Product Description

The 3M 7000000743 is a Roloc Bristle Disc designed for surface conditioning on metal workpieces. The disc mounts to a Roloc-style quick-change hub and spins to flex individual bristle tips against the surface, delivering controlled abrasive action at 80 grit. At 2 inches in diameter with a 5/8-inch tapered arbor configuration, it fits compact right-angle die grinders commonly used by HVAC technicians, pipefitters, welders, and fabricators. The yellow color coding identifies the 80-grit classification. Light operator pressure produces a consistent surface condition without gouging or removing base material, making it suitable for cleaning, light rust removal, and prep work before coating or brazing.

This bristle disc is used in trade applications where a controlled, repeatable surface finish is needed on metal parts. Typical scenarios include prepping pipe fittings and sheet metal flanges before brazing or soldering, removing mill scale or light oxidation from steel, and cleaning weld zones. Its flexible bristle design allows it to work into contoured and irregular surfaces that flat abrasive discs cannot reach effectively. It is sold individually and is a single-use consumable replaced as bristle tips wear down.

Key Features

• 80-grit abrasive rating for light material removal and surface conditioning
• 2-inch diameter fits compact right-angle die grinders and Roloc-compatible tools
• Tapered 5/8-inch arbor for quick-change Roloc hub mounting
• Flexible bristle construction conforms to irregular and contoured metal surfaces
• Yellow color coding for quick grit identification in the field
• Light pressure operation reduces risk of workpiece damage

Compatibility

Designed for use with Roloc-style quick-change mandrels on right-angle die grinders. Confirm mandrel thread and hub size match the 5/8-inch tapered specification before installation.

Installation Notes

Installation is performed by pressing the disc onto a Roloc quick-change mandrel until it seats securely. Ensure the grinder is unplugged or the air supply is disconnected before mounting or removing the disc. Wear appropriate eye protection and gloves during operation, as bristle tips can shed at speed. Follow tool manufacturer RPM ratings and do not exceed the disc's rated maximum RPM.
