Product Details
The 3M™ paper belt 364UZ measures 43" x 75" with a P150 grit aluminum oxide abrasive, constructed with a premium aluminum oxide mineral in an open coat design for loading resistance, coated on an F-weight paper backing known for its rigidity and ability to achieve finer finishes than cloth-backed belts of the same grade. The paper backing ensures smooth operation and durability, while the open coat structure resists loading especially on soft wood. The belt incorporates 3M Dust Management Technology to reduce static cling in dust particles, facilitating easier evacuation when used with an efficient dust collection system. The belt ends are joined with a sine wave splice that enhances belt strength, resists hinging and splice fatigue, travels smoothly over contact wheels and platens, minimizes chatter marks, and supports smooth operation in either direction for consistent finishing. The aluminum oxide abrasive is chosen for its toughness, durability, self-fracturing properties that expose fresh cutting edges, high cut-rate, hardness, strength, and low heat retention, making it suitable for sanding and finishing a wide variety of substrates, including woodworking and metalworking on ferrous alloys. The product comes with warranty information as specified by 3M standards.
