Product Details
3M™ Scotch-Brite™ Heavy Duty Hand Pad 7440B Aluminum Oxide Med Grit-40 Pads measure 6" x 9" and are designed for cleaning, finishing, and graining on a variety of surfaces including metal, wood, and composites. The non-woven material resists loading and can be rinsed clean, providing consistent finishing action throughout the pad's life. This product performs effectively on both flat and contoured surfaces without significantly altering the base material. The aluminum oxide mineral used in this pad is a tough and durable abrasive that self-fractures to expose fresh cutting edges during use, unlike traditional abrasives that wear down quickly. Notable for its high cut-rate, hardness, strength, and low heat retention, aluminum oxide is widely utilized in grinding applications as well as sanding and finishing tasks. The Scotch-Brite™ Extra Duty Hand Pad is also suitable for denibbing or defuzzing. This versatile pad can be used by hand for precise control, with a hand block for uniform finishing, or on an in-line sander to condition larger areas. Featuring fine grade aluminum oxide abrasive, this brown pad is preferred by industrial professionals for its cutting efficiency and longevity. Aluminum oxide is effective on a wide range of substrates in both woodworking and metalworking applications, including ferrous alloys. The Scotch-Brite™ industrial abrasives consist of abrasive minerals combined with non-woven nylon or synthetic fibers, creating a system that delivers consistent results throughout the product's lifespan. The open-web material operates cool and is resistant to clogging, ensuring high performance during use. Applications include surface conditioning, with key industries including marine.
