Product Introduction
The 3M™ Paper Sheet 346U is constructed of aluminum oxide and comes in a range of grades and sizes to accommodate many different projects. The paper backing is durable for coarse sanding yet flexible enough to be used on curved surfaces. Its cut-rate and durability make it an excellent choice for blending the joints of connecting pieces. Aluminum oxide is a very hard mineral that maintains sharp points longer than natural abrasives. The abrasive grains are adhered with space between them (open-coat construction) to minimize the buildup of dust on the paper’s surface.
3M™ Paper Sheet 346U Features
- Tough aluminum oxide abrasive cuts fast and performs well on many surfaces.
- Load-resistant, open-coat feature enables longer use before replacement.
- Strong, D-weight paper backing supports aggressive sanding.
- Sheets are conformable to various workpieces.
- Usable by either hand or machine.
- Comes in a number of sizes to accommodate various applications.
3M™ Paper Sheet 346U Applications
- Blending the joints of connecting pieces in woodworking.
