Frequently Asked Questions

Which backup pad system do these discs fit?

These discs feature the 3M Roloc TR mounting style, which uses a threaded plastic male button that locks into standard Roloc TR rubber backup pads with a half-turn twist. They do not fit Roloc TS or TP button systems.

Are backing pads or mandrels included with this assortment?

Not included.

What should I expect regarding the mixed condition of this assortment?

Nine discs are unused new old stock, including all eight 2-inch 60-grit discs and the 3-inch Rapid Cut wheel. The remaining four 3-inch Scotch-Brite discs have seen light shop use, with working abrasive web remaining across their faces.

A quarter-turn snaps a fresh disc into place so you can transition from aggressive weld cleanup straight into final blending without breaking your stride. Spin them up, work the edges smooth, and keep the project moving.
