The 3M 7100010402 is a purpose-built 3” x 132” 984F Cubitron II ceramic belt made for demanding stainless steel work. Precision-shaped ceramic grains cut quickly while maintaining a predictable finish for production environments. With an 80+ grit specification, this belt blends aggressive stock removal and controlled surface refinement for weld blending and part prep. A YF-weight polyester cloth backing delivers dependable strength and dimensional stability under repeated loading. Closed-coat construction increases active abrasive coverage, so the 3M cubitron 984F II ceramic belt sustains cutting action longer. Single-flex design supports cylindrical, centerless and manual backstand grinders common in precision shops. The Film-Lok splice provides a low-profile, reliable joint for continuous duty and reduced risk of splice failure. An integrated grinding aid helps manage heat for safer finishing on stainless and carbon steel substrates. Suitable for wet or dry use, the 3M 7100010402 is versatile across polishing, deburring, and finishing operations. Choose this 80 grit 3M cubitron solution when you need repeatable throughput, longer belt life and consistent results.
Precision-Shaped Ceramic Grain
The precision-shaped ceramic abrasive in the 3M 7100010402 stays sharp longer for faster stock removal and consistent finishes.
80+ Grit, Balanced Cut and Finish
This 80 grit sanding disc, equivalent to a belt, offers the sweet spot between aggressive grinding and controllable surface quality for metalwork.
YF-Weight Polyester Backing
A robust cloth backing ensures the 3M cubitron 984F II ceramic belt resists tearing and tracks reliably on cylindrical and centerless grinders.
Closed-Coat for Extended Life
Higher abrasive coverage reduces loading and sustains cutting performance, improving uptime versus open-coat alternatives.
Film-Lok Splice & Single-Flex Build
The Film-Lok splice gives a smooth joint, while single-flex construction adapts the belt to a variety of machines and applications.
