3M™ Hookit™ Gold Disc Dust Free 236U, 01079, 6 in, P180, 100 discs per carton, 4 cartons per case

The 3M Hookit Gold Disc 236U represents a comprehensive solution for automotive body sanding applications, offering a versatile grade range spanning from P80 to P180. This broad selection accommodates various sanding requirements, from aggressive material removal to refined finishing work. The disc features a durable C-weight paper backing that provides structural integrity and longevity throughout extended use. Its robust construction makes it particularly well-suited for demanding auto body projects, including rough feather-edging of damaged areas, refinement of surface scratches on exposed metal substrates, systematic paint removal around compromised sections, and numerous other specialized finishing tasks. Available in both 3-inch and 6-inch diameter configurations, the Hookit Gold Disc 236U demonstrates compatibility with a wide spectrum of substrate materials including clear coats, fiberglass reinforced composites, body fillers, ferrous and non-ferrous metals, existing paint layers, plastic components, and automotive putty compounds.

The disc incorporates an open coat construction methodology combined with aluminum oxide mineral abrasive technology. This engineering approach delivers a notably sharper cutting action compared to equivalent closed coat abrasives of identical grades, while simultaneously preventing the accumulation of dust residue on the working surface. The strategic spacing of abrasive particles promotes superior dust evacuation, thereby maintaining consistent cutting performance throughout the sanding process.

The open coat construction of the 3M Hookit Gold Disc 236U deliberately positions abrasive grains with deliberate spacing between them, facilitating the efficient removal and evacuation of sanding dust and particulate debris. This design strategy effectively prevents the clogging and dulling of the abrasive cutting edges that would otherwise occur during extended use. Furthermore, the load-resistant coating applied to the abrasive grains enables continuous cutting performance even when working with challenging materials such as paints, body fillers, putties, and other substances that typically tend to accumulate on sanding surfaces and compromise productivity.

This advanced construction approach yields measurable benefits including substantially increased operational productivity and significantly reduced consumption of abrasive materials. The specialized 6-hole perforation pattern featured on select versions of the 3M Hookit Gold Disc 236U further enhances dust removal efficiency, particularly when integrated with dedicated vacuum extraction systems. The hole configuration design eliminates the requirement for precise alignment with the sander's backup pad, thereby streamlining disc changes and reducing downtime between applications.

Aluminum oxide stands as the preferred abrasive mineral among experienced industrial professionals, commanding widespread adoption due to its exceptional cut-rate velocity and extended operational lifespan. This engineered mineral composition creates an exceptionally tough and durable abrasive matrix that employs a self-fracturing mechanism. This self-fracturing property continuously exposes fresh, sharp cutting edges as the surface becomes dulled through use, contrasting sharply with traditional natural abrasives that gradually lose their cutting effectiveness without edge renewal. The combination of rapid cut-rate performance, superior hardness characteristics, and exceptional strength properties establishes aluminum oxide as the ideal choice for grinding, sanding, and finishing applications across diverse industrial contexts. Its particular suitability for metalworking operations involving ferrous alloys and specialized automotive body applications makes it an industry standard for professional-grade work.

3M has developed a comprehensive product portfolio of hook-and-loop style Hookit sanding discs specifically engineered for work environments where traditional adhesive-backed discs may encounter contamination from accumulating dust, dirt, or airborne debris particles. These innovative discs conveniently and securely attach to a complementary hook-and-loop backup pad (available separately) mounted on random orbital sanders. The Hookit system design enables effortless removal and repositioning of discs without adhesive residue, facilitating complete cleaning and allowing for repeated redeployment of discs throughout their complete abrasive service life.

The 3M Hookit Gold Disc 236U represents the culmination of rigorous scientific development and engineered strength, integrating precision-manufactured abrasive grains with a reinforced backup disc pad attachment system. This comprehensive design philosophy delivers extended disc longevity, consistently maintained sharp cutting performance, and exceptional dust resistance characteristics, ultimately enabling superior operational results in demanding automotive body finishing
