3M 7010309818 Non-woven Abrasive Disc 5 Inch Medium

Product Description

The 3M 7010309818 is a non-woven aluminum oxide abrasive disc designed for light coating removal on ferrous and non-ferrous metal substrates. At 5 inches in diameter with a maximum operating speed of 10000 RPM, this medium-grade disc is built for tasks such as removing paint, rust, sealant, and varnish without damaging the underlying material. The open-web construction resists loading, keeping the mineral cutting sharp and extending abrasive life. It mounts via a Hook and Loop backing system, compatible with 3M Hook and Loop back-up pads sold separately. HVAC, plumbing, and general metal fabrication tradespeople reach for this disc when a controlled, consistent surface prep result is needed.

This disc is suited for light-duty surface prep applications on residential and commercial job sites. It is particularly useful when working on metal components that require coating removal before welding, sealing, or refinishing. The conformable open-web design allows the disc to follow contoured surfaces, making it a practical choice for irregular geometries common in ductwork, pipe fittings, and structural metal. Its finer finish and greater conformability set it apart from heavier strip discs when the goal is substrate preservation alongside coating removal.

Key Features

• Medium-grade aluminum oxide mineral cuts fast without harming the substrate
• Open-web construction resists loading to maintain cutting performance and prolong disc life
• Conformable design follows contoured and irregular metal surfaces
• Hook and Loop backing mounts quickly to compatible 3M Hook and Loop back-up pads
• Effective on paint, rust, sealant, and varnish removal from ferrous and non-ferrous metals
• Lighter duty and finer finish compared to heavy-strip abrasive discs

Compatibility

Designed for use with 3M Hook and Loop back-up pads sold separately. Suitable for light coating removal on ferrous and non-ferrous metal substrates in general metal surface preparation applications.

Installation Notes

This disc is installed by general tradespeople, fabricators, and surface prep technicians using compatible random orbital or angle grinder tools equipped with a Hook and Loop back-up pad. Before mounting the disc, ensure the tool is powered off and disconnected from its power source. Do not exceed the rated maximum speed of 10000 RPM. Inspect the disc for damage before each use and replace if the abrasive web shows signs of tearing or excessive wear.
