• 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.

Trusted 3M Paper Sheet

The 3M Paper Sheet 346U is a reliable choice for sanding tasks. This model features an 80 D-weight paper backing that balances strength and flexibility, making it suitable for various surfaces.

Its design supports aggressive sanding while maintaining durability. The 3M brand ensures consistent quality, ideal for both professional and DIY projects.

Precise Size And Format

Each sheet measures 3-2/3 inches by 9 inches, providing a convenient size for detailed work and easy handling. This dimension fits well in hand sanding or machine applications.

Durable D-weight Backing

The 80 D-weight paper backing offers strong support for the abrasive surface. This backing is tough enough to handle aggressive sanding without tearing or wearing out quickly.

Its durability also means the sheets conform well to various workpieces, including curved surfaces. This flexibility enhances the sanding quality across different materials.

Effective Open-coat Feature

The load resistant open-coat design helps extend the sheet’s usable life by reducing dust buildup. This feature keeps the abrasive grains sharp and effective longer than traditional sandpapers.

By spacing the abrasive grains, the sheets avoid clogging during sanding, especially on softer materials. This results in consistent cutting performance and less frequent replacement.

Large Case Pack Count

The product is available in a case containing 2000 sheets, ideal for large-scale or ongoing sanding projects. This bulk quantity ensures you have enough material for multiple jobs.

Having a large pack count reduces the need for frequent reordering and helps maintain productivity. It’s a practical choice for workshops or industrial settings.
