F-weight is one of the heaviest, most rigid paper backings available and will achieve finer finishes than cloth backed belts in the same grade. The paper backing provides smooth operation and durability. On the abrasive side, the ceramic abrasive surpasses conventional abrasives in high production environments for its aggressive cut, greater heat resistance and extremely long life.
This belt also features 3M dust management technology that reduces static in the dust particles, allowing them to be pulled away more easily when coupled with an efficient dust collection system. To support desired finishing results, the belt ends are joined using a sine wave splice that promotes belt strength and resists hinging and splice fatigue. The splice travels smoothly over contact wheels and platens, minimizes chatter marks, and promotes smooth operation for consistent finishing results. Abrasive grain density for this belt series increases for each higher grade to offer the optimal balance between surface finish and load resistance; the higher the grade, the finer the finish. P-graded abrasive grains in 3M paper belts are screened to a finer tolerance than non-P-graded abrasives and produce a more uniform surface finish.
3M™ Paper Belt 966UZ features 3M™ Ceramic Abrasive Grain. This abrasive exceeds conventional abrasives in durability, life, and cut-rate, offering greater throughput in less time and significant gains in productivity. 3M™ Ceramic Abrasive Grain is a ceramic mineral formed using a proprietary process to enhance toughness and hardness of the grain. It is chemically engineered with a unique "stay sharp" crystalline structure, which continually self-sharpens cutting edges on the surface of the belt, ensuring extended high performance in heavy-duty production applications.
Abrasive belts come in many different widths and lengths and are used on a variety of different belt sanding tools for many different applications on both wood and metal. At 3M we offer a broad selection of belts to fit most any industrial belt sander. Wider belts are used to dimension and sand large wooden panels, smooth rough cut edges of metal sheets, or add a grain pattern to stainless steel sheets and medium-width belts fit onto edge or portable belt sanders for sanding or blending wood pieces such as cabinet doors.
