Operators convert the Scotch-Brite™ Cut and Polish Unitized Block into custom sizes and shapes for their unique applications. This tightly layered, durable, unitized abrasive block is available in fine and medium densities, and works well for aggressive deburring, blending and finishing on harder metals.
- Tightly layered, dense unitized construction provides aggressive cut on harder metals
- Suitable for tough blending, finishing and deburring on harder metals like stainless steel, carbon steel and high nickel alloys
- Flexible, nonwoven construction provides controlled abrasive action to help prevent undercutting or gouging
- Scotch-Brite™ material resists loading and wears uniformly to provide continuous cutting action
What is the size of the 3M Scotch-Brite Cut and Polish Unitized Block?
The size of this unitized block is 22 inches x 18 inches x 1/16 inch.
What does "5A FIN" mean in the description of this product?
"5A FIN" specifically refers to the abrasive grade. This product has a fine abrasive grade, which makes it ideal for blending and finishing on metal surfaces.
How many units are included in one case of this product?
One case includes just one unitized block.

Aluminum Oxide Mineral Has High Cut-Rate, Hardness and Strength
The Scotch-Brite™ Cut and Polish Unitized Block is filled with aluminum oxide abrasive mineral. This mineral is popular among industrial professionals due to its cut-rate and long life. It is a tough, durable abrasive that self-fractures to expose fresh cutting edges in use. Traditional abrasives, such as garnet, quickly wear down with use. Aluminum oxide mineral has high cut-rate, hardness, strength, and low heat retention, making it a good choice in grinding applications. It is suitable on a wide variety of substrates in both woodworking and metalworking, including ferrous alloys.
The Cut and Polish Unitized Block is available in two grades – fine (FIN) and medium (MED). Finer grades are used when operators desire a softer cut and finer finish. Conversely, a medium grade would be used when operators desire a more aggressive cut and coarser finish.
Discover the Scotch-Brite™ Advantage
Scotch-Brite™ abrasives are unique due to their nonwoven technology. Abrasive mineral is interspersed on synthetic fibers using resin, creating an open web construction. Spaces between the fibers permit excess material to escape, so the mineral does not become worn down by debris. It keeps the mineral cutting sharper longer, enhancing cut performance and increasing abrasive service life. The spring-like nature of the fibers works well on contours and responds to subtleties on the surface. Its responsive design effectively removes unwanted burrs, soils, and contaminants without ruining the base material, so you get a consistent and uniform finish — part after part.
