3M™ SiC Cloth Belt 490FZ, P50 ZF-weight, 52 in x 103 in, Sine-lok Precision Roll Grinding, Single-flex, 2 ea/Case

Narrowing It Down

Featuring the right blend of mineral, backing and bond, 3M™ SiC Cloth Belt 490FZ is designed for coarse and intermediate/fine wood sanding operations where good cut rate and finish are required. . Wide abrasive belts are used with wide belt sanders to dimension or finish wood panels. The cloth belt is available in two weights: ZF-weight (grades P24 – P50) or YF-weight (grades P60 – P220). Both weights are stiff, sturdy and durable, with ZF being the slightly heavier of the two. These strong backings support the abrasive side of the belt and provide the durability needed for these high horsepower applications. Choose a coarser grade, like P24, when you desire aggressive sanding. Choose a finer grade, like P220, when a fine finish is your top priority.

What are the essentials for most primary wood applications? Fine finishes, definitely. But, during sanding, having a load-resistant abrasive can come in handy too. It's no secret that wood generates a lot of dust and debris during sanding. This belt is made with silicon carbide mineral, because it is a hard synthetic mineral that provides excellent finishes when compared to the other types of minerals used in wood sanding. It is one of the best minerals available for wood finishing.

To help the mineral do its job well, a static-resistant treatment is added to the belt. This additive helps the dust collection system funnel dust and debris away from the mineral, so it doesn't get clogged by debris. Additionally, the semi-open coat construction means there are small gaps between the mineral. These tiny channels help prevent the abrasive from loading. The mineral is adhered to the backing with a resin bond that breaks down gradually during sanding. The bond helps with heat resistance and provides the bond strength needed for these high horsepower applications.

Altogether, 3M™ SiC Cloth Belt 490FZ is a great abrasive belt to have on hand for wood sanding operations that require backing strength and excellent finishes. Crafting the right blend of mineral, backing, bond and coating is science. Applying the right woodworking techniques and processes is an art.
