Quick-Change Sanding Disc

This 3M 361F disc uses a TR quick-change system for fast swaps on compatible sanders. Aluminum oxide abrasive on a YF-weight polyester backing provides coarse 60-grit material removal. The 1-1/2 inch diameter suits detail work and tight contours. Maximum operating speed is 30,000 RPM for high-speed applications.

Metal finishing and wood shaping

The coarse grit and heat-resistant coating suit aggressive stock removal on metal, wood or composite surfaces. The TR attachment requires a matching quick-change backup pad. Buyers needing fine finishing grits or a different attachment system such as hook-and-loop should select another product. The 50-piece pack supports extended production runs.

60 grit aluminum oxide

This single specification defines the cutting aggressiveness and surface finish the disc delivers. Coarse 60 grit removes material quickly but leaves visible scratch patterns that require finer steps for a smooth result. Verify that your sander accepts TR quick-change discs and that 30,000 RPM does not exceed the tool rating before use.

Questions about this item

How long does the 30,000 RPM maximum speed last before the abrasive wears down?

The aluminum oxide grain on the YF-weight polyester backing maintains cutting performance through extended use at the rated 30,000 RPM maximum operating speed until the coarse 60 grit surface is consumed.

Does the TR quick-change system generate extra heat or vibration during all-day sanding?

The TR quick-change attachment locks securely to the backup pad, minimizing run-out and heat buildup so the disc runs true during continuous operation.

Which backup pad diameter and attachment style do I need to mount these 1-1/2 inch TR discs?

A 1-1/2 inch diameter backup pad with a matching TR (Type R) quick-change interface is required to secure and drive these discs.
