3M 7100100999 | Roloc 2" Diameter 782C 80+ Grit Precision Shaped Ceramic Fibre Disc

Description

The 3M 7100100999 is a compact, high-performance 2" Roloc fiber disc made to remove material quickly from carbon steel and other ferrous alloys. The 3M Cubitron II Fibre Roloc disc, employs precision-shaped ceramic grain to deliver fast cut rates while reducing operator force and disc change frequency. Its closed-coat structure and stiff fiber backing prevent loading and tear-out during weld grinding, beveling, and edge refinement. The TR Roloc quick-change attachment secures the disc for repeatable alignment and tool-free swaps, thereby increasing production and repair uptime. In confined or recessed work areas, an open, specification-driven design results in predictable disc life and consistent performance. This 2-inch 3M Roloc disc is designed for right-angle grinders and disc sanders, where accuracy and accessibility are critical. Buyers looking for measurable improvements in throughput and abrasive life will find the 3M abrasive disc ideal for heavy shop applications and precision finishing operations.

Product Features and Benefits

Precision-Shaped Grain for accelerated cut-rate

3M 782C PSG forms sharp, triangular cutting peaks that slice metal efficiently, producing higher removal rates than conventional ceramic abrasives with less operator pressure.

80-grit closed coat for consistent stock removal

The 80+ grit grade balances aggressive removal with a controllable finish—ideal for weld blending, chamfering, and edge prep where repeatable results are required.

Stiff fibre backing for tear resistance

The 3M Cubitron II Fibre Roloc Disc rigid fiber backing supports the abrasive under medium-to-high pressure, reducing deformation and improving life on edge work and heavy passes.

Roloc TR quick-change for fast swaps

Quick, tool-free attachment minimizes downtime and ensures reliable concentric mounting across operators and tools, improving process repeatability.

Compact 2" size for tight access

Small diameter permits work in recessed areas and close to fixtures where larger discs cannot reach, extending the disc’s utility in assembly and repair.
