3M 7100117789 | 984F x 36+ Grit x 132.000" OAL Precision Shaped Ceramic Cloth Belt

Description

The 3M 7100117789 Cubitron II 984F 36+ grit cloth belt is built for precision heavy-cut and controlled finishing on high-value alloys. At 1.5" x 132", this 3M cubitron 984F ii ceramic belt offers a long-reach format ideal for continuous grinding and extended-contact applications. Precision-shaped ceramic grains slice aggressively yet fracture cleanly to expose new cutting points, delivering consistent material removal on cobalt and nickel alloys. A YF-weight polyester cloth backing provides dimensional stability and strength during high-speed use on benchtop motors and wide-belt systems. Closed-coat abrasive density maximizes cutting life and provides predictable performance comparable to a 36 grit sanding disc in industrial settings. Film-Lok splice ensures a low-profile, durable joint for smooth tracking on cylindrical grinders, centerless grinders, and pressure-assist backstands. Single-flex construction balances flexibility and support for platen, conveyorized, and manual backstand equipment in wet or dry operations. Designed for grinding, deburring, surface preparation, polishing and finishing, the belt handles titanium substrates without excessive heat transfer. Use the 3M 7100117789 where a 36 grit grinding disc-level removal is required, but you need extended runtime and repeatable results. This belt delivers professional-grade cut rates and finish control, reducing changeovers and improving throughput in production environments.

Product Features and Benefits

Precision-Shaped 36+ Ceramic Grain

Delivers aggressive, long-lasting cutting action that sustains performance on cobalt, nickel and titanium, outlasting common 36 grit sanding disc options.

Extended 132" Length for Long Runs

The 1.5" x 132" format reduces belt changes and increases contact time on large jobs or continuous processing lines, improving uptime.

Film-Lok Splice for Smooth Tracking

Low-profile Film-Lok splice minimizes vibration and splice failures on high-speed equipment, ensuring consistent finish quality throughout the run.

YF-Weight Polyester Backing

Robust backing resists tearing and delivers thermal stability under load, protecting both belt integrity and sensitive alloy metallurgy.

Closed-Coat Construction for Predictable Life

High abrasive coverage produces uniform wear and reliable cutting rates, ideal when 36 grit grinding disc performance and repeatability matter.

Frequently Asked Questions

What materials is the 3M 7100117789 best suited for?

The 3M 7100117789 is optimized for cobalt and nickel alloys and performs well on titanium where a 36 grit sanding disc and level cut are required.

What are the exact dimensions and grit of this Cubitron belt?

This belt is 1.5" (38.1 mm) wide by 132.0" (3352.8 mm) long and features 36+ precision-shaped ceramic grits for heavy cutting and finishing.

Can I use this belt wet or dry on centerless grinders and platen systems?

Yes, the 3M 7100117789 is rated for wet or dry use and is suitable for benchtop motors, centerless grinders, wide-belt sanders and platen systems.

How does this belt compare to a 3M 36 grit Roloc disc?

The belt offers comparable aggressive stock removal to a 3M 36 grit Roloc disc but at production scale with longer life and better belt tracking.

What is 36 grit sandpaper used for, and where does this belt fit in the workflow?

36-grit sandpaper is used for heavy stock removal and initial shaping; the 3M Cubitron II 984F 36+ grit cloth belt provides that same coarse-cut function on larger workpieces with industrial durability.
