3M 7000047074 Surface Conditioning Disc 4.5 in Medium

Product Description

The 3M 7000047074 is a Surface Conditioning RC Disc designed for deburring, blending, cleaning, and finishing operations on composites and soft metals. Built with Aluminum Oxide abrasive on a non-woven RC (surface conditioning) material, it delivers reliable initial cut rate along with extended cutting life under average to moderate pressure. The disc mounts via a Hook and Loop attachment system, making pad changes fast during production or service work. At 4.5 inches in diameter, it fits standard right-angle grinders and die grinders rated for disc use. Metalworkers, fabricators, and finishing technicians use this disc for surface prep and coating removal work.

This disc is suited for flat surface applications on composites, aluminum, and other soft metals where controlled material removal and a consistent finish are required. It performs well in blending weld seams, removing light scale or oxidation, and prepping surfaces before coating or bonding. The medium grade rating positions it for general-purpose use where aggressive stock removal is not required. The Hook and Loop backing allows quick attachment to compatible 4.5-inch backup pads, making it practical for high-volume repetitive finishing tasks in fabrication shops, maintenance facilities, and light manufacturing environments.

Key Features

• Aluminum Oxide abrasive on RC non-woven material for consistent cut rate and extended disc life
• Medium grade suited for blending, coating removal, finishing, and light deburring
• Hook and Loop attachment for fast disc changes on compatible backup pads
• High edge durability and flexibility for controlled surface contact
• Most effective on flat surfaces made of composites or soft metals
• 4.5-inch diameter fits standard right-angle and die grinder configurations

Compatibility

Designed for use with 4.5-inch Hook and Loop backup pads on right-angle grinders and die grinders rated to 8000 RPM or higher. Best suited for composites and soft metals including aluminum. No specific OEM model compatibility was stated in the product data.

Installation Notes

Installation and disc changes should be performed with the grinder powered off and unplugged or air supply disconnected. Confirm the backup pad and grinder are rated for the disc diameter and RPM before mounting. Inspect the disc for damage before each use and do not exceed the 8000 RPM maximum rated speed. Disc mounting and use should follow applicable ANSI B7.1 safety standards for abrasive products.
