Built on a durable film backing with an aluminum oxide abrasive grain, this 3-inch disc operates at up to 15000 RPM and delivers a close-tolerance, consistent finish on demanding substrates. The film backing resists edge tearing, making it more durable than standard A-weight paper-backed discs in high-cycle use. Open coat construction limits loading and promotes an aggressive, consistent cut rate throughout the disc's service life.\u003c\/p\u003e\u003cp\u003eThis disc is suited for sanding and finishing on plastics, gel coats, polyurethane solid surfaces, composites, and fiberglass. It is commonly used in automotive refinishing, marine hull finishing, composite fabrication, and other production finishing workflows where surface quality and disc longevity both matter. The Hookit attachment system allows fast disc changes and reuse, reducing downtime during high-volume finishing operations.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAluminum oxide abrasive grain delivers fast cut rate and extended service life across a wide range of substrates\u003c\/li\u003e\n\u003cli\u003eFilm backing resists edge tearing and provides greater durability compared to standard A-weight paper discs\u003c\/li\u003e\n\u003cli\u003eOpen coat construction reduces loading on the disc surface for a more aggressive, consistent cut\u003c\/li\u003e\n\u003cli\u003eHookit hook-and-loop attachment allows quick disc changes and disc reuse throughout its working life\u003c\/li\u003e\n\u003cli\u003eP400 grit designation for fine finishing and surface preparation on gel coats, composites, and solid surfaces\u003c\/li\u003e\n\u003cli\u003eRated to 15000 RPM for compatibility with standard random orbital and disc sanders used in production settings\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with Hookit hook-and-loop backup pads accepting 3-inch coated abrasive discs.
