The 3M 7100078984 Cubitron™ II 984F is a premium 132-inch abrasive cloth belt made for demanding metalworking and industrial finishing operations. Utilizing precision-shaped ceramic grain technology, the belt delivers rapid, repeatable cutting performance throughout its service life as the engineered grains continually fracture to expose fresh, sharp cutting points for sustained aggressive material removal. Constructed on a durable, high-quality YF-weight polyester cloth backing and finished in a red closed-coat design, the belt is thermally stable for low-to-medium pressure applications and resists loading on titanium and other challenging substrates.
The 80-grit grinder variant balances aggressive stock removal with a controlled surface finish, while the belt’s low heat-transfer characteristics help minimize burns and thermal discoloration during extended periods of use. This product supports robotic and pressure-assisted grinding cells, reducing changeouts and downtime; the Film-Lok splice provides a smooth, seamless joint that improves accurate tracking, reduces vibration, and delivers consistent surface results in high-speed, belt-driven equipment.
With its robust construction and precise dimensions, 132 inches (3352.8 mm) in length and 2 inches (50.8 mm) in width, the Cubitron II 984F belt is appropriate for finishing, deburring, grinding, and surface preparation tasks in production environments. It is well suited to industrial users who prioritize measurable performance, extended belt life, fewer belt changes, and consistent part quality across repetitive operations.
Precision-Shaped Ceramic Grain for Fast, Consistent Cutting
The 3M 7100078984 has grain geometry that slices through metal and continuously fractures into new sharp points, maintaining a high and consistent cut rate over time.
Film-Lok Splice for Smooth, Reliable Tracking
The Film-Lok splice design delivers a seamless joint, enabling accurate belt tracking, minimal vibration, and improved consistency on high-speed grinding equipment.
Durable YF-Weight Polyester Backing for Industrial Strength
Built with a tough YF-weight polyester cloth backing, the belt delivers excellent tear resistance and stability for demanding grinding and finishing operations.
Closed Coat Construction Reduces Loading
A closed coat helps prevent clogging on titanium and nickel alloys, improving belt life and maintaining cut efficiency.
Heat-Management To Limit Burn and Discoloration
Material and bonding systems are engineered to run cooler under load, lowering the risk of heat-related surface defects.

What is the advantage of the precision-shaped ceramic abrasive?
The precision-shaped grains cut more efficiently than conventional abrasives, maintaining sharpness longer and reducing heat buildup for a cleaner finish.
Can the 3M Cubitron II cloth 984F belt be used with both wet and dry processes?
It is specifically made for tough materials such as titanium, cobalt, and nickel alloys, offering reliable performance across multiple metalworking applications.
What type of materials can this belt work on?
3M 80 grit sanding belt It is ideal for use on titanium, cobalt, and nickel alloys and works efficiently with manual backstands, centerless grinders, and cylindrical grinders for industrial finishing tasks.
Can I use it in robotic grinding cells?
Yes, the belt’s YF backing and precision grain reduce changeouts and are well suited for robotic and low- to medium-pressure-assisted cobalt chrome and nickel alloy applications.
What backing and splice does it have?
The belt uses a Film-Lok splice that creates a seamless joint for stable tracking, reduced machine vibration, and consistent, smooth finishing results.
