About this item

  • Grit Textures: Each Cratex size and shape is made in four standard grit textures or compositions which differ in accordance with the mesh size of the abrasive grain used. Coarse (Green) Medium (Dark Brown) Fine (Reddish Brown) and Extra Fine (Grey Green).
  • Cratex Blocks and Sticks are excellent hand tools for cleaning and polishing metal surfaces, for breaking edges, smoothing away high spots, removing rust, heat marks, tarnish and stains. Designed for either manual or mechanical operation, they can be mounted in tool holding fixtures, chucks, or cradles.
  • Use them for polishing shafts...damaskeening...cleaning and dressing diamond wheels...polishing rotating cylindrical parts, cleaning calibrations and reference points, and for removing feather edges and touching up cutting tools, dies, chisels and other sharp edged tools.

Works like expected. Cratex is spendy stuff, but worth it.

I use it for finishing fine screw threads. I just press it into the threads while the lathe is running.

I bought this to see if it would work as well as a Bright Boy for cleaning model train tracks. I chopped off a 1/2" chunk and used it to clean some really nasty rails and it worked like a charm! Much cheaper and economical than a Bright Boy, too!
