3M Scotch-Brite 7447 PRO General Purpose Hand Pad, 6" x 9", Very Fine, Maroon (Box of 60)

Superior Metal Prep and Finishing for Welders

For professional welders and fabricators, surface preparation is critical to achieving high-quality welds and finishes. The 3M Scotch-Brite 7447 PRO General Purpose Hand Pad is the ultimate tool for prepping base metals and finishing completed welds. This box of 60 pads offers a high-performance solution that outperforms standard abrasive pads and traditional steel wool. The 7447 PRO features tightly graded aluminum oxide abrasive particles that cut fast and leave a smooth, consistent scratch pattern, ensuring your metal surfaces are perfectly primed for welding or final finishing.

One of the biggest challenges in welding preparation is avoiding contamination. Steel wool can leave behind tiny iron fibers that rust and cause inclusions or surface defects, especially on stainless steel and aluminum. The Scotch-Brite 7447 PRO eliminates this risk entirely. Its non-woven nylon web construction is rust-proof and resilient, resisting tearing and splintering even under vigorous use. This makes it the safe and effective choice for cleaning oxides from aluminum before TIG welding or removing heat tint from stainless steel welds without gouging the parent metal.

The versatility of the 7447 PRO pad is unmatched in the welding shop. Its 6x9 inch size covers large areas quickly, but it can also be folded or cut to fit into tight corners and around pipe diameters. The "Very Fine" grade is aggressive enough to remove light rust and mill scale but fine enough to blend grinder marks and leave a professional satin finish. Whether you are prepping a critical joint or putting the final touch on a custom fabrication project, these pads deliver consistent results every time. The PRO technology ensures that the abrasive mineral is exposed continuously, providing a consistent cut throughout the life of the pad.

Welding & Fabrication Benefits
