3M 04304 Scotch-Brite Non-Woven Aluminum Oxide Hook Loop Disc - Very Fine

The surface conditioning disc comes in a wide variety of grades and sizes and is an ideal first-step for cleaning, blending, deburring, and finishing. Durable, non-woven fiber construction conforms well on irregular or contoured surfaces without undercutting or damaging the base material. This surface conditioning disc uses aluminum oxide abrasive. Aluminum oxide is a popular choice among industrial professionals because of its cut-rate and long life. This mineral is a tough, durable abrasive that self-fractures to expose fresh cutting edges in use, whereas traditional abrasives, such as garnet, quickly wear down with use.

Due to its high cut-rate, hardness, strength, and low heat retention, aluminum oxide mineral is widely used in grinding applications in addition to sanding and finishing use. Aluminum oxide is suitable on a wide variety of substrates in both woodworking and metalworking, including ferrous alloys.
