3M™ Paper Disc 363I, P100 F-weight, 4-1/2 in x 7/8 in, Die 450E

Tough Hand Sanding
3M™ Paper Disc 363I is suited for either metal or wood sanding and finishing thanks to its durability and fast cutting abrasive material. Its heavy F-weight paper backing can be cut to fit any work piece or hand tool.

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 and metalworking.

Heat and Load Resistant
This paper disc is constructed using a semi-open coat of abrasive grains that helps to balance both load resistance and fine finishing action. It also uses a resin bonding which is specially designed to resist thermal deterioration, which can occur during sanding. This bond is very tough and excellent for work on a variety of substrates. This also allows for faster sanding and a higher cut rate.

• Designed for aggressive sanding on a variety of surfaces
• Aluminum Oxide abrasive cuts fast and provides a consistent, fine finish
• Semi-open construction balances fine finishing with load resistance
• Heavy F-weight paper backing resists tearing in the machine and hands on applications
• Resin bonding construction increases durability and resists wear
