Description
The 3M 7000121724 Quick Change P.A.R.T. Disc Mandrel is a specially designed mandrel for attaching Standard Abrasives Quick Change P.A.R.T. discs to rotary power tools. This Standard Abrasives Disc Mandrel is designed for repeatable surface prep and precise paint/anodized contact cleaning. It has a 1/4" (6.35 mm) shank and a 3.0" (76.2 mm) overall length for easy access in recessed or close-tolerance areas. The mandrel indexes the P.A.R.T. disc, allowing the disc's self-aligning center hole to clean the contact point without removing any adjacent anodized material. With the mandrel and rotary tools that accept a 5/8" collet assembly, you can perform rivet-hole prep, grounding-point cleaning, and paint removal with precise, measurable results. This 3M Disc Mandrel for Rotary Tool is quick-change compatible and designed to fit seamlessly into production or maintenance workflows that require consistent, localized removal.
