3M 7100020493 Surface Conditioning Disc 5 Inch Medium Ao

Product Description

The 3M 7100020493 is a Surface Conditioning FE abrasive disc engineered for edge work, deburring, and blending on metal surfaces. Built on a flexible FE substrate with an Aluminum Oxide (AO) abrasive grain, it delivers high initial cut rate and maintains that cut rate over the life of the disc. At 5 inches in diameter with a 0.62-inch arbor, this disc is sized for standard angle grinders and disc tools used in metal fabrication and finishing applications. The medium grade makes it well-suited for stock removal tasks where high contact pressure is applied to ferrous materials.

This disc is designed for use on both flat and contoured metal surfaces, making it a practical choice for HVAC sheet metal work, plumbing rough-in cleanup, electrical panel fabrication, and general metal prep. It performs well on ferrous materials under high contact pressure and handles blending, light coating removal, and surface finishing in a single tool setup. The Hook and Loop attachment system allows fast disc changes, reducing downtime during repetitive operations.

Key Features

• Aluminum Oxide grain on FE substrate provides high initial and sustained cut rate
• High edge durability and flexibility for use on contoured and flat surfaces
• Suited for blending, coating removal, surface finishing, and light deburring
• Most efficient on ferrous materials under high contact pressure
• Hook and Loop attachment for fast, tool-free disc changes
• 5-inch diameter with 0.62-inch arbor fits standard angle grinder and disc tool configurations

Compatibility

Designed for use with 5-inch Hook and Loop disc backing pads fitted with a 0.62-inch arbor, compatible with standard angle grinders and random orbital tools that accept this disc size.

Installation Notes

Installation and disc changes should be performed with the power tool unplugged or the battery removed. Confirm the tool arbor size and backing pad type match the disc specifications before mounting. Wear appropriate PPE including eye protection and gloves when operating abrasive discs. Inspect the disc for damage before each use and do not exceed the tool or disc rated RPM.
