3M FN510079273 Flap Wheel Roloc Interleaf 2.5x1.25 80G

SKU CH-65YD-K13CX MPN FN510079273

Abrasive interleaf flap wheel with 80 grit aluminum oxide and non-woven coating for surface finishing at up to 9,000 RPM

  • TypeSanders
  • Coarse 80 grit removes material quickly
  • Interleaf construction blends cutting and finishing
  • 5 inch diameter fits Roloc holders
  • 9000 RPM max speed for high-speed tools
  • 1/4 inch TR+ shank secures firmly

Purpose and user

This 3M flap wheel combines coated and non-woven abrasive material for simultaneous material removal and surface finishing. It suits metalworkers and fabricators who need to blend welds, remove light scale or prepare surfaces for coating in a single step.

Build integration

The TR+ shank locks into a Roloc quick-change holder on a die grinder or rotary tool, freeing the operator from collet changes between grits. Aluminum oxide construction resists loading on ferrous metals, while the interleaf design keeps the cutting action cool on contoured parts.

Upgrade path

It replaces separate coated flap discs and non-woven surface-conditioning wheels, cutting change-over time on jobs that demand both stock removal and a uniform satin finish. The jump is worthwhile when workflow speed outweighs the slower cut rate of pure coated abrasives.

Questions about this item

How long can the 3M FN510079273 flap wheel run at its 9,000 RPM maximum before the aluminum oxide grit wears down?

The wheel uses aluminum oxide abrasive with a coarse grade and X-weight backing, designed for sustained material removal at the rated 9,000 RPM until the flaps are consumed.

What heat or vibration should I expect when running this 2.5-inch Roloc wheel continuously on a die grinder?

The interleaf coated and non-woven construction reduces loading and runs cooler than solid flap wheels, while the TR+ shank minimizes vibration at full speed.

Which Roloc tool holder or backup pad matches the TR+ shank on this 80-grit wheel?

The 1/4-inch TR+ shank requires a compatible Roloc TR+ holder or backup pad with the same quick-change interface for secure mounting.
