3M Scotch-Brite 4-1/2 in. Hook and Loop Sanding Disc, Grit, Aluminum Oxide

The 3M™ Scotch-Brite™ hook-and-loop sanding disc offers an ideal first-step for cleaning, blending, deburring, and finishing. This surface-conditioning disc features durable, nonwoven fiber construction that conforms well on irregular or contoured surfaces without undercutting or damaging the base material. The open-web material also runs cool and resists loading, while the evenly distributed aluminum oxide abrasives produce a high cut-rate for consistent finishing. As a tough, durable abrasive, aluminum oxide self-fractures to expose fresh cutting edges in use, whereas traditional abrasives such as garnet, quickly wear down with use.

• Aluminum oxide mineral offers hardness, strength, and low heat retention for use in grinding applications.
• Use in woodworking and metalworking, including ferrous alloys.
• Also suitable for composite, plastics, and other materials.
