Norton 666233-77542 Hook Loop Paper Disc 5 Inch 150 Grit

Product Description

The NORTON 666233-77542 is a 5-inch, 150-grit hook and loop paper disc designed for fine grit finishing and micro-finishing tasks on a wide range of surfaces. Built on a C-weight latex and paper backing, this disc stays flexible and conforms to contours while resisting tears under load. The aluminum oxide abrasive is P-graded for consistent stock removal and a cool cut that minimizes heat buildup. A water-based, non-loading stearate coating reduces clogging and extends disc life between changes. Rated to 15000 RPM, this disc is suited for use with random orbital sanders and right angle grinders in automotive, woodworking, and composite finishing applications.

This disc is used in residential and commercial finishing environments where surface prep quality is critical. It performs well on aluminum, fiberglass, wood, composites, and painted or primed surfaces. The hook and loop attachment system makes mounting and swapping discs fast, reducing downtime during production or repair work. It is a practical choice for body shop technicians, finish carpenters, composite fabricators, and general tradespeople who require a reliable fine-grit disc for surface prep and micro-finishing stages.
