The disc combines aluminum oxide mineral abrasive with ceramic grain to deliver consistent cut rates across a range of sanding stages. At 5 inches in diameter and 180 grit, it is suited for finish sanding and surface prep work prior to primer or topcoat application. A multi-hole pattern supports dust extraction and reduces loading during use. The Hookita hook-and-loop style attachment system allows for fast disc changes without tools, reducing downtime on the job.\u003c\/p\u003e\u003cp\u003eThis disc is designed for automotive body and paint shops handling collision repair, paint prep, and surface refinishing tasks. The 180 grit rating positions it for intermediate to finish sanding steps, where controlled material removal and a consistent scratch pattern are required before applying primer or sealer. The multi-hole configuration aligns with most standard backup pads used in professional auto body environments, supporting effective dust extraction when paired with a vacuum or sander with dust collection capability.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCeramic and aluminum oxide mineral blend for consistent cut across sanding stages\u003c\/li\u003e\n\u003cli\u003eMulti-hole disc pattern reduces loading and supports dust extraction\u003c\/li\u003e\n\u003cli\u003eAnti-loading coating helps prevent debris from clogging the cutting surface\u003c\/li\u003e\n\u003cli\u003eHookita hook-and-loop attachment allows fast, tool-free disc changes\u003c\/li\u003e\n\u003cli\u003eEnhanced resin bond improves disc durability and finish consistency\u003c\/li\u003e\n\u003cli\u003e5 inch diameter at 180 grit for intermediate to finish sanding applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with standard 5 inch hook-and-loop backup pads compatible with the Hookita attachment system; multi-hole pattern is engineered to align with most common backup pad hole configurations used in automotive refinishing.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and disc changes should be performed with the sander powered off and disconnected from its air or power source. Confirm the backup pad surface is clean and free of debris before attaching the disc to ensure full Hookita engagement.
