Scotch-Brite™ Light Grinding and Blending Disc, GB-DH, Super Duty A Coarse, 4 in x NH, 100 ea/Case

• 2-IN-1 TIMESAVER: Built to grind and blend small welds in a single step, as well as blend, deburr, finish, and refine workpieces
• AGGRESSIVE CUTTING ACTION: Tough enough for the heaviest surface conditioning jobs, including blending coarse grind lines, while increasing productivity and removing the final sanding step
• WORKS ON A RANGE OF METALS: Great for use on aluminum, mild steel, nickel alloy, stainless steel, and titanium
• QUICK AND EASY ATTACHMENT: The hook and loop backing makes for easy disc attachment, removal, and re-attachment in multi-step processes; these discs are also available with a center hole option that is compatible with a retainer nut or center post attachment system for accurate centering

The Scotch-Brite™ Light Grinding and Blending Disc uses a ceramic abrasive grain blend to achieve a high cut-rate for optimal weld grinding and blending in mild-steel applications. In these instances, Light Grinding and Blending discs are designed to effectively blend and refine a grade 36 scratch or finer.

Additionally, the Scotch-Brite™ Light Grinding and Blending Disc can often single-handedly prepare surfaces for painting, where a 3 mil or greater paint thickness is being applied, without adding a final dual-action sanding step.

The 3M™ ceramic aluminum oxide abrasive blend is a ceramic mineral designed using one of our proprietary processes to enhance toughness and hardness of the grain for a higher-level performance. 3M ceramic aluminum oxide abrasive is engineered to fracture frequently and surpasses aluminum oxide abrasives in both cut-rate and durability. Perfect for moderate to heavy stock removal as well as finishing, ceramic abrasives are built to cut fast and handle intense heat and stress applications.

Scotch-Brite™ abrasives are unique surface conditioning products with abrasives incorporated into non-woven fiber matrix. Combining abrasives and non-woven material creates an abrasive system that delivers consistent results for the life of the product. The open-web material runs cool and is load resistant, which keeps the abrasive minerals cutting at high performance by limiting clogging of the fibers.

3M offers a complete line of hook-and-loop style 3M™ Hookit™ discs for work spaces where adhesive backed discs may become contaminated by dust, dirt, or flying debris.
