Tackle Hard-to-Reach Areas
Scotch-Brite Surface Conditioning Disc Pack 9145S contains a variety of 4.5 inch diameter discs that can be used with a right angle grinder. The small diameter of these discs make them a good match for small to mid-size workpieces with hard-to-reach areas. Some are made with silicon carbide mineral and others are made with aluminum oxide mineral. All discs are color coded by grade. This helps reduce the risk for error and enhance productivity, as operators can easily identify the next abrasive in the sequence. Grades range from super fine (SFN) to coarse (CRS).
Benefits of Open Web Abrasives
Nonwoven technology makes our Scotch-Brite abrasives unique. We intersperse abrasive mineral on synthetic fibers using resin ? creating an open web construction. Spaces between the fibers permit excess material to escape, so the mineral does not get 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.
Our Scotch-Brite Surface Conditioning Disc Packs are a good option for operators who want to sample a variety of discs. We created these versatile packs as an economical solution for testing discs with different minerals and grades. Each application is nuanced. Factors like machinery or equipment, base material and part specifications all influence which abrasive should be used. That?s why our Scotch-Brite Surface Conditioning Disc Packs were created ? to help you find the right disc for you.
