3M™ Cloth Belt 464W, 320 YF-weight, 4 in x 48 in, Film-lok, Single-flex, 50 ea/Case

3M™ Cloth Belt 464W is best suited for metal sanding and finishing thanks to its durability and fast cutting abrasive material. Its heavy, polyester cloth backing provides smooth operation and durability and can conform to the shape of contoured parts for consistent finishing. The abrasive side features closed coat construction for aggressive sanding and a distinct blue-black color helps to easily differentiate it from other grits and grains.

This paper primarily uses silicon carbide, which is a popular choice among industrial professionals because of its fast cut-rate and smooth finish. This synthetic mineral is very hard and fractures easily, resulting in freshly exposed sharp edges that cut extra fast and produce a smooth, professional-looking finish. Silicon carbide products are commonly used for low-pressure applications such as cleaning and finishing on wood and metal. While it wears faster than aluminum oxide, it produces a finer finish.

This sheet also uses a resin bonding which is specially designed to resist thermal and chemical deterioration, which can occur during sanding. This bond is very tough and excellent for precision work on hard and soft surfaces. This also allows for faster sanding and a higher cut rate. The waterproof polyester backing material enables the user to rinse areas of the workpiece and the cloth during use to prevent dust and debris from clogging the points of the abrasive, while producing a faster cut at the same time.

• Tough, YF-weight cloth backing offers excellent durability in sanding applications
• Silicon carbide mineral and cork particles provide an aggressive cut and a fine finish
• Resin bonding resists deterioration from heat, extending the life of the abrasive belt
• Flexible cloth material conforms to contoured parts for consistent finishing
• Closed coat provides greater grain density and finer finish on hard surfaces
• Waterproof polyester material allows for easy debris removal
