3M 777F Ceramic Sanding Belt
The 3M 777F ceramic sanding belt measures 2 inches by 132 inches with a 60 grit rating. It is built for metalworkers and fabricators who need aggressive stock removal on tough alloys. The closed-coat ceramic abrasive cuts fast while resisting heat buildup. This belt fits stationary belt sanders that accept the specified length and width.
Sustained Cutting Performance
Ceramic grain fractures continuously to expose fresh cutting edges during long grinding sessions. The resin bond and polyester YF-weight backing resist heat degradation when pressure is held for extended periods. Closed coating prevents loading so the belt keeps cutting instead of glazing over. Medium grade balances removal rate with surface finish on stainless and carbon steel.
Polyester Backing With Butt Joint
The YF-weight polyester backing provides high tensile strength and tear resistance for heavy-duty use. A butt joint creates a smooth, low-profile splice that reduces vibration marks on the workpiece. The orange colour identifies the 777F series at a glance in a busy shop. This belt is not suited for wide-contact finishing machines that require wider belts.
