3M 7000028230 Abrasive Disc Roll 5 Inch P320 Grit

Product Description

The 3M 7000028230 is a coated abrasive disc roll in the Stikita 236U series, designed for surface preparation and finishing work in professional trade and industrial settings. Each disc features a pressure-sensitive adhesive backing for fast attachment and removal, paired with a durable C-weight paper substrate that holds up under aggressive sanding pressure. The aluminum oxide mineral delivers consistent cut rate across a wide range of materials. At P320 grit, this roll is suited for fine finishing, pre-paint prep, and between-coat sanding where a smooth, uniform surface is required. The roll format eliminates individual disc liners, keeping workflow efficient on busy job sites.

This disc roll is intended for use with a compatible Stikita backup pad, sold separately. It is well suited for finish carpentry, metal fabrication shops, auto body prep, and general surface conditioning work where repeated disc changes are common. The roll format gives technicians quick access to fresh abrasive without fumbling with individually packaged discs, making it practical for production environments and service vans alike. The load-resistant coating helps extend abrasive life by reducing premature disc loading during use.
