• Load resistant open-coat feature enables longer use before replacement
• Sheets are conformable to various workpieces and usable by either hand or machine
• Sheets come in a number of sizes to accommodate various applications
• Strong, D-weight paper backing supports aggressive sanding
• Tough aluminum oxide abrasive cuts fast and performs well on many surfaces

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 this an excellent choice for blending the joints of connecting pieces in wood- and metal-working.

Aluminum oxide is a very hard mineral that maintains sharp points on the grains much longer than natural abrasives such as emery or garnet. The abrasive grains are adhered to the sandpaper with some space between them, known as open-coat construction, to minimize the buildup of dust on the surface of the paper, which would otherwise load the abrasive points. Loading often results from sanding soft materials and can clog the abrasive, shortening the usable life of the sandpaper sheet.

Durable D-Weight Backing

The 80 D-weight paper backing is strong enough to handle tough sanding jobs. It supports the abrasive grains firmly, preventing premature wear and allowing for aggressive material removal.

This backing also offers flexibility, which is useful when sanding curved or irregular surfaces. It helps maintain contact with the workpiece, improving sanding effectiveness and finish quality.

Effective Abrasive Technology

The sheets use tough aluminum oxide abrasive, known for fast cutting and long-lasting sharpness. This abrasive performs well on many surfaces, including wood and metal, making it a versatile choice.

The open-coat design reduces dust buildup by spacing abrasive grains apart. This feature extends the sheet's usable life, especially when sanding softer materials that tend to clog abrasives quickly.
