The disc measures 4.331 inches in diameter and features a load-resistant coating that resists clogging from dust and debris. It is suited for trades and finishing professionals who require tight tolerances and repeatable results across multiple finishing steps.

This disc is used in wood finishing, solid surface composite work, plastic, fiberglass, paint preparation, coating and corrosion removal, primer sanding, e-coat, and metal finishing applications.
