5" Billet Aluminum Hook & Loop Sanding and Polishing Backing Pad (5/8"-11 Thread)

Our 5-Inch Billet Aluminum Hook & Loop Sanding Backing Pad features a precision CNC-machined solid aluminum body, standard 5/8"-11 female threads, built-in wrench flats for easy tool changes, and a heavy-duty hook-and-loop face.Product detailsBuilt for heavy-duty metal polishing, body shop prep, and stone work, our 5-inch Billet Aluminum Backing Pad is engineered to eliminate the flex and heat distortion typical of plastic or rubber backing plates. CNC-machined from solid aluminum, this rigid backing pad maintains complete flatness across the entire surface—ensuring uniform pressure, crisp edges, and maximum cut from your sanding discs and polishing pads. Featuring a heavy-duty hook-and-loop face, high-speed disc swaps take seconds. The standard 5/8"-11 female threaded arbor directly threads onto most 7" high-speed rotary polishers, 4.5"/5" angle grinders, and extension shafts without needing extra adapters. Integrated hex wrench flats give you a secure grip for effortless installation and removal. Key Features & Specifications: Material: Precision CNC-machined billet aluminum body Size: 5" Diameter (125 mm) Thread Fitting: Standard 5/8"-11 female thread Attachment Type: Heavy-duty hook and loop (Velcro) Design: Low-profile, ultra-rigid flat face with integrated hex nut wrench flats Heat Resistance: High thermal conductivity prevents heat buildup and protects adhesive bonds during heavy grinding Where It’s Used: Metal Detailing & Restoration: Preparing aluminum tanks, stainless steel trim, forged wheels, and brass components for mirror polishing. Stone & Concrete Fabrication: Flat-surface beveling, edge finishing, and face polishing on granite, marble, quartz, and concrete countertops. Auto Body & Paint Prep: Leveling filler, feather-edging paint, and wet or dry block sanding. Why It’s Used over Plastic/Rubber Backers: Zero Flex for True Flatness: Plastic and foam plates bend under heavy hand pressure, causing rounded edges or uneven "wavy" cut patterns. The rigid aluminum core ensures complete surface contact and uniform stock removal. Heat Dissipation: Metal-on-metal sanding generates substantial friction. Solid aluminum acts as a heat sink, drawing heat away from the disc face to extend sandpaper life and keep the hook-and-loop bond from melting. Extreme Durability: Will not crack, warp, or wear down under high torque or wet sanding conditions.
