3M 7100199448 Scotch-brite Surface Conditioning Disc 4.5 in

Product Description

The 3M 7100199448 is a Scotch-Brite Surface Conditioning Low Stretch Disc, a nonwoven abrasive tool designed for cleaning, finishing, blending, and deburring metal surfaces. The disc measures 4.5 inches in diameter with a 7/8 inch arbor hole and features an open-web aluminum oxide construction. Its low-stretch backing adds stiffness for better control during use. The load-resistant nylon web resists clogging, which extends abrasive life and reduces downtime. This disc is suited for metalworking operations where maintaining part geometry is critical. Fabricators, machinists, and maintenance technicians reach for this disc when consistent surface conditioning results are required across a range of metal substrates.

This disc is used in residential and commercial fabrication, maintenance, and finishing environments. Typical applications include weld blending, surface prep before coating, light deburring, and general metal conditioning. The conformable open web adapts to contoured or irregular surfaces without removing material aggressively, making it appropriate for finishing work where dimensional accuracy matters. It is designed for use with standard right-angle grinders or disc sanders equipped with a 7/8 inch arbor.

Key Features

• 4.5 inch diameter with 7/8 inch arbor hole for standard angle grinder fitment
• Aluminum oxide (AO) mineral for consistent cutting on a variety of metals
• Open-web nonwoven nylon construction resists loading and buildup
• Low-stretch backing provides added stiffness and better disc control
• Conformable web adapts to surface irregularities without altering part geometry
• Suitable for cleaning, finishing, blending, and deburring in one disc

Compatibility

Designed for use with right-angle grinders and disc sanders that accept a 7/8 inch arbor, standard in most 4.5 inch angle grinder configurations used in metalworking and fabrication applications.

Installation Notes

Installation and disc changes must be performed with the grinder unplugged or power isolated. Verify the grinder arbor size matches the 7/8 inch arbor before mounting. Inspect the disc for damage before each use and do not exceed the rated RPM of the tool or disc. Wear appropriate PPE including eye protection and gloves during operation and disc changes.
