GP Disc designed for paint and anodize removal at electrical grounding contact points and small holes in metal surfaces. The disc measures 5\/8 inch in diameter and is built from resin-reinforced nylon fibers loaded with Aluminum Oxide mineral. It operates at up to 12000 RPM. The center hole geometry self-aligns so the disc cleans only the workpiece hole, leaving the surrounding anodized layer intact. It mounts via a Quick Change TS attachment system, requiring a P.A.R.T. Disc Mandrel sold separately. Licensed electricians and metalwork technicians are the primary installers of this tool.\u003c\/p\u003e\n\u003cp\u003eThis disc is used in electrical maintenance and metalwork applications where anodized coatings must be selectively removed from grounding contact points or similar small recessed surfaces on metal components. It is suited for both production and field service environments where consistent, repeatable contact-point cleaning is required. The disc is available in multiple grades, allowing the technician to match abrasive aggressiveness to the specific surface condition and desired finish. Typical applications include aerospace, automotive, and industrial electrical grounding prep work on anodized aluminum parts.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5\/8 inch diameter sized specifically for small grounding contact points and holes in metal surfaces\u003c\/li\u003e\n  \u003cli\u003eSelf-aligning center hole geometry cleans the workpiece hole while preserving the surrounding anodized layer\u003c\/li\u003e\n  \u003cli\u003eAluminum Oxide mineral delivers sharp cutting action with a fine finish result\u003c\/li\u003e\n  \u003cli\u003eResin-reinforced nylon fiber construction resists wear for extended abrasive service life\u003c\/li\u003e\n  \u003cli\u003eQuick Change TS attachment allows fast disc swaps without tools\u003c\/li\u003e\n  \u003cli\u003eRated to 12000 RPM for compatibility with standard die grinders and rotary tools\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with a P.A.R.T.
