Description
3M Paper Disc 346U is a general purpose abrasive sanding paper constructed on a heavy, D-weight backing and features an open coat construction to help prevent loading. The aluminum oxide abrasive and lightweight backing make this paper an ideal product for sanding applications such as paint prep and wood sanding.Fine Hand Sanding
Our 3M™ Paper Disc 346U is best suited for wood sanding thanks to its durability and fast cutting abrasive material. Its D-weight paper backing can be cut and folded to fit any work piece or hand tool, and distinct brown color to easily differentiate it from other grits and grains.
Aluminum Oxide Abrasive
Aluminum oxide is a popular choice among industrial professionals because of its fast cut-rate and long life. This mineral makes a tough, durable abrasive that self-fractures to expose fresh cutting edges, whereas traditional natural abrasives dull more quickly. Due to its fast cut-rate, hardness and strength, it is widely used for sanding and finishing applications. Aluminum oxide is suitable for use on a wide variety of materials in woodworking.
Open Coat Resists Loading
Sanding paper cuts better and lasts longer when dust isn’t clogging the cutting surface of the abrasives. The open coat construction of this paper means the abrasive grains are placed with space between them to help evacuate sawdust and other sanding debris and avoid clogging the cutting edge of the grains. This allows the sheet to continue cutting even when sanding softwoods, paints and other materials that would, otherwise, clog the grain and hinder sanding ability. Additionally, the open coat feature provides a more aggressive cut than a comparable closed coat abrasive of the same grade. All of this adds up to increased productivity and reduced material consumption.
