3M 7100239042 | 984F x 120+ Grit x 84.000" OAL Precision Shaped Ceramic Cloth Belt

Description

The 3M 7100239042 Cubitron II 984F 120+ grit ceramic belt is made for precision finishing and light stock removal on metallic substrates. Measuring 0.5” wide with an 84.0” overall length (2133.6 mm), this narrow-format belt suits small grinders, tooling jigs and detail finishing applications. Precision Shaped Ceramic grains provide self-sharpening performance that sustains cutting speed and extends life compared with conventional abrasives. A cloth backing with YF-weight construction ensures stable tracking and tear resistance in both manual and automated processes. Closed-coat abrasive distribution increases effective cutting area for predictable cut rates and uniform surface quality during polishing and deburring. The Film-Lok splice delivers a durable, low-vibration joint that improves reliability in continuous-use finishing systems. With a 120+ grit specification, the belt excels at final surface preparation, blending and preparing parts for subsequent finer finishing stages. Single-flex construction allows use on standard belt fixtures and specialized finishing equipment across carbon steel and alloy components. Compatible with wet or dry operations, this Cubitron 984F belt performs consistently in coolant-assisted and dry finishing workflows. Select the 3M 7100239042 for repeatable fine finishing, efficient material removal and the trusted performance of the 3M cubitron 984F II ceramic belt family.
