Quick-Change Disc for Power Sanders

The 3M 22402 361F disc fits power sanders that accept a TR quick-change system. Aluminum oxide grain on a YF-weight polyester backing delivers medium-grade cutting action for surface preparation and finishing tasks. Each pack contains fifty 2-inch discs rated for up to 20,000 RPM. Professional technicians and serious DIY users will find the closed-coat construction suited to general material removal.

Polyester Backing and TR Mount

The blue YF-weight polyester backing resists heat buildup during extended sanding sessions. A TR quick-change fastener lets operators swap discs in seconds without tools, reducing downtime between grit changes. Closed-coat coverage distributes aluminum oxide grains evenly across the surface for consistent scratch patterns. The 2-inch diameter reaches tight contours and interior corners that larger discs cannot access.

P100 Grit Defines the Cut

P100 grade positions this disc between coarse stock removal and fine finish sanding. It removes primer, paint or light corrosion faster than finer grits while leaving a surface ready for subsequent finishing steps. Buyers who need aggressive material removal or ultra-fine polishing should select a different grit. The fifty-disc pack supports high-volume workflows in automotive refinishing and metal fabrication.
