Scotch-Brite™ EXL Unitized Block is a strong, durable high-performance block built for a wide range of deburring and finishing applications. One of the best benefits of a unitized block is that it can be converted into another form: shape it into mounted points, use it by hand or bond it to tools for honing.

  • EXL material offers great durability and edge retention for tough burrs and sharp edges
  • Highly durable block is suitable for a wide range of deburring and finishing applications
  • Cut-to-size block may be shaped according to application
  • Available in a range of grades, minerals and densities
  • Nylon fibers break down to expose fresh mineral, leading to more consistent finishes
  • Gaps between fibers permit debris to escape, helping with load resistance

  1. What is the size of the Scotch-Brite™ EXL Unitized Block?

    The size of this unitized block is 6 in X 3/4 in X 3/4 in.

  2. How many pieces are included per case?

    There are 10 pieces included per case of Scotch-Brite™ EXL Unitized Blocks, with each piece restricted to one box due to its specific usage.

  3. What is the abrasive grade of this product?

    This product has an abrasive grade of 2S FIN, which makes it perfect for blending and finishing on both flat surfaces and edges.

  4. Can I use this product for heavy-duty applications such as industrial cleaning or surface preparation prior to adhesive bonding?

    Although strong and durable, we recommend other products suited explicitly for such heavy-duty jobs. Scotch-Brite™ EXL Unitized Block's strength shines brightest when used primarily for deburring, metalworking, blending welds or marks removal tasks on various surfaces including metals like stainless steel or aluminum.

Tailored to Fit: Picking Mineral, Grade and Density

The Scotch-Brite™ EXL Unitized Block comes in various variations, making it easy for operators to find an abrasive that suits their application. The unitized densities range from 2 to 8. A density of 2 is a good choice when trying to keep part geometry intact. Low-density abrasives are flexible and soft, which makes them conform better to the workpiece. On the other hand, if a workpiece requires a stiffer, harder abrasive, a density of 8 may be a better choice. The unitized block comes in multiple densities to suit various requirements depending on the workpiece and application.

In addition to densities, operators can choose from different grades of aluminum oxide and silicon carbide. Aluminum oxide is a synthetic mineral known for its high cut-rate, hardness, strength, and low heat retention. It is suitable for a wide variety of substrates in both woodworking and metalworking, including ferrous alloys. Silicon carbide is used for creating different aesthetic finishes. It tends to wear faster than aluminum oxide but leaves brighter finishes.

Built for Strength

The Scotch-Brite™ EXL Unitized Block offers uniform benefits, including durability and consistency. Unitized products are produced by compressing and curing multiple layers of abrasive material together. The tough and layered unitized construction gives the abrasive more durability, helping it resist wear and stand up to tough areas like edges and contours.

The Many Benefits of Scotch-Brite™ Abrasives

Nonwoven technology makes Scotch-Brite™ industrial abrasives unique. A combination of fiber strands, resin, and abrasive mineral forms a thick, open web. The spring-like nature of the fibers responds to contours and effectively removes unwanted burrs, soils, and contaminants while maintaining the geometry of the workpiece. This reduces rework and boosts productivity. Gaps in the web allow swarf to escape, so debris does not clog the mineral. Fibers in the web continually break down with use to reveal fresh mineral for consistency, sharp cut, and long service life.

From aesthetic finishing to weld blending, deburring, and more, Scotch-Brite™ abrasives work fast and deliver consistent results, part after part.
