Built on E-weight paper backing with a ceramic and aluminum oxide blend abrasive bonded with resin, this disc delivers consistent cut rate and extended service life. The open coat construction minimizes loading when working over fresh body filler, paint, or bare metal. At 8 inches in diameter with a 40 grit rating, it is suited for shaping, stripping, and scratch refinement tasks performed by body shop technicians and surface prep professionals.\u003c\/p\u003e\u003cp\u003eThis disc is used in automotive collision repair, metal fabrication, and surface preparation applications. It excels at shaping plastic body filler and putty, removing paint down to bare metal, and refining scratches prior to priming. The Hookit hook-and-loop attachment system allows fast disc changes without tools, reducing downtime during production work. Some versions in the 255U series include a 7- or 8-hole pattern to improve dust evacuation when used with compatible vacuum or dust-collection backing pads.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCeramic and aluminum oxide blend abrasive for strong cut rate and extended disc life\u003c\/li\u003e\n\u003cli\u003eE-weight paper backing provides added rigidity and durability under load\u003c\/li\u003e\n\u003cli\u003eOpen coat construction resists loading on fresh filler and soft materials\u003c\/li\u003e\n\u003cli\u003eHookit hook-and-loop attachment enables fast, tool-free disc changes\u003c\/li\u003e\n\u003cli\u003e8-inch diameter at 40 grit suited for aggressive shaping and paint removal\u003c\/li\u003e\n\u003cli\u003eCompatible with dust-extraction backing pads featuring matching hole patterns\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with Hookit hook-and-loop backup pads accepting 8-inch coated abrasive discs.
