Cratex Rubber-bonded Abrasives are used in a widely diversified list of industries - on production and assembly lines, in finishing operations, in tool and machine shops, in the production of basic tools, instruments, component parts and for maintenance and repairs.

Each Cratex product is made in four standard Grit Textures or compositions which differ in accordance with the mesh size of the abrasive grain used.

   (C) Coarse              (M)  Medium                (F) Fine               (XF)  Extra –Fine  
     (Green)               (Dark Brown)          (Reddish Brown)           (Grey Green)    

In making Cratex Rubberized Abrasives, Silicon Carbide grain is screened according to grit size and suspended in a premium grade oil-resistant chemical rubber.  Although silicon carbide is more expensive than other abrasive materials, it is used because it has a high level of purity and has been found to be the best for the broadest range of light deburring, smoothing, cleaning, and polishing applications on ferrous and non-ferrous alloys as well as many non-metallics, such as glass.  In contrast to conventional grinding wheels, the Cratex bond has a unique cushioning action, that cuts freely, smoothly, and softly without gouging or digging into the work surface. It resists clogging or smearing, and is ideal for smoothing and polishing without loss of dimensional tolerances or control. 

Some typical applications include: breaking edges, radiusing and polishing out high spots, removing rust, cleaning threads, smoothing the edges of punched or sheared metals, deflashing, smoothing and polishing molds, dies , and other production tools, sharpening and honing of cutting dies, blades and edged tools, removing corrosion, excess solder, heat marks, cleaning and polishing contact points, jacks, electrodes, removing tool marks, scratches, light burrs, and fins, blending in welded seams after rough grinding, engine turning, damaskeening, polishing engine ports, shafts, turbine blades, smoothing glass edges, jewelry finishing, gem stone sanding and many others.
