The PS73 6-inch (150mm) sandpaper disc is engineered for professionals who demand consistent results: heat-treated aluminum oxide abrasive, an advanced electrostatic coating that locks the grain to a tear-resistant B-weight paper, and a special anti-clog layer that keeps dust from packing into the surface. The 9-hole dust extraction pattern aligns perfectly with most 6-inch random orbital sanders, pulling debris away so you get a cleaner cut and longer disc life. From heavy paint stripping to fine surface prep, one disc handles it all with zero drama.\n  \u003c\/p\u003e\n\n  \u003c!-- 产品特点竖向列表，便于SEO收录 --\u003e\n  \u003ch3 class=\"ps73-section-title\"\u003e🔧 Key Features of 9-Hole Hook \u0026amp; Loop Sandpaper Discs\u003c\/h3\u003e\n  \u003cul class=\"ps73-features\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eHeat-Treated Aluminum Oxide Grain:\u003c\/strong\u003e Specially processed for enhanced sharpness and durability, these abrasives deliver a fast, consistent cut on metal, wood, primer, and composites without premature dulling.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eAnti-Shedding Electrostatic Coating:\u003c\/strong\u003e Grains are applied via an electrostatic process and bonded to a flexible, tear-resistant B-weight paper backing, dramatically reducing grit detachment even under heavy pressure.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eAnti-Clog Stearate Coating:\u003c\/strong\u003e A specialized surface treatment prevents paint, primer, and resinous dust from packing into the abrasive, significantly extending disc life and maintaining cut speed.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003ePre-Punched 9-Hole Dust Pattern:\u003c\/strong\u003e Optimized for 6-inch random orbital sanders with 9-hole dust extraction—efficient debris removal keeps your workspace cleaner and your sandpaper cooler.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eStrong Hook \u0026amp; Loop Backing:\u003c\/strong\u003e Grips securely to the sander pad during dry sanding, yet peels off effortlessly in seconds for rapid grit progression—no slipping, no adhesive residue.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eFull Grit Range Available:\u003c\/strong\u003e Choose from ultra-coarse 60-grit for rapid stock removal all the way up to 10000-grit for professional mirror polishing.

Will this 9-hole disc fit my 6-inch random orbital sander?\u003c\/dt\u003e\n    \u003cdd\u003eYes, as long as your sander uses a standard 6-inch (150mm) backing pad with a 9-hole dust extraction layout. The 9-hole pattern is one of the most common configurations for random orbital sanders in the automotive and woodworking industries. Always match the hole count to your backing pad—this disc is designed for 9-hole pads.\u003c\/dd\u003e\n\n    \u003cdt\u003e2. Can I use these on a sander without dust extraction holes?\u003c\/dt\u003e\n    \u003cdd\u003eYou can, but it's not ideal. The 9 holes are pre-punched to channel dust away. If your sander has a solid pad, a portion of the abrasive surface is reduced by the holes. For solid pads, we recommend a 0-hole disc for full surface contact. However, the disc will still function normally and the hook and loop attachment will hold fine.\u003c\/dd\u003e\n\n    \u003cdt\u003e3. What grit should I choose for automotive paint prep?\u003c\/dt\u003e\n    \u003cdd\u003eFor stripping old paint or leveling body filler, start with 80–180 grit. For smoothing and shaping, move to 240–400 grit. Before primer or paint, use 600–1500 grit for a fine surface. If you're wet sanding or polishing between clear coat layers, 2000 grit and above delivers a mirror finish. The PS73 disc handles every stage.\u003c\/dd\u003e\n\n    \u003cdt\u003e4. How does the anti-clog coating work?\u003c\/dt\u003e\n    \u003cdd\u003eThe coating is a zinc stearate-based compound that lines the abrasive surface. During dry sanding, it acts as a barrier preventing paint, primer, or resin from sticking to the grains. The electrostatic grain application further ensures each particle stands upright and sheds dust naturally as the sander vibrates, so the disc keeps cutting long after standard paper would be packed.\u003c\/dd\u003e\n\n    \u003cdt\u003e5. Is the B-weight paper backing durable enough for auto body contours?\u003c\/dt\u003e\n    \u003cdd\u003eAbsolutely. B-weight latex-saturated paper is specifically chosen for its balance of flexibility and tear strength. It conforms to curves, door edges, and panel contours without cracking, yet resists tearing much better than standard A-weight or C-weight light paper. This makes it ideal for both heavy body filler shaping and fine finish sanding.\u003c\/dd\u003e\n\n    \u003cdt\u003e6. Can these discs be used for wet sanding?\u003c\/dt\u003e\n    \u003cdd\u003eNo, these are dry sanding discs. The stearate coating and paper backing are not designed for water or liquid lubricants; using them wet will cause the backing to deteriorate and the coating to fail. For wet sanding, choose a disc specifically marked for wet\/dry use.\u003c\/dd\u003e\n  \u003c\/dl\u003e\n\u003c\/div\u003e\n\n\u003c!-- 内嵌样式，完全封装在 .ps73-product-desc 作用域内
