Buff and Shine 3" Flex Edge D.A & Drill Backing Plate is a 3" Flex Edge backing plate for DA polishers and drills—built for tight spots, contours, and small-pad work on boats and cars. Flex-edge geometry helps the plate follow mild curves so 3" pads stay planted in hardware zones, swim platforms, and other areas large plates cannot reach. Why detailers keep it on the cart Diameter: 3" Flex Edge face for small-pad correction Female 5/16"-24 thread for compatible DA machines Includes drill-chuck adapter path (max 3000 RPM on drill) Ideal for tight topsides, around fittings, and contour work SKU: 300Y How to use Thread onto a compatible DA (5/16"-24 female) or use the drill chuck adapter as specified Seat a matching 3" hook-and-loop pad fully on the face Keep the plate flat on the panel; respect max RPM (especially on drill—max 3000 RPM) Note: Confirm thread and RPM limits for your machine before first use—drill use is limited vs DA.
