India Abrasive File · Aluminum Oxide · Produces Long Lasting Edges Falcon Tool India Abrasive Files are made of aluminum oxide abrasive which is the preferred abrasive for producing exceptionally sharp, long lasting edges and for high quality steel work. They are brown in color and filled with oil during the manufacturing process. India Combination Bench Stones produce keen, long lasting edges with their unique combination of coarse and fine grit aluminum oxide abrasive. They are ideal for clean deburring and will produce sharp edges and quality finishes. The coarse grit side is 120 grit and the fine grit side is 320 grit. Available in both round and rectangular shapes. The round stone is 4" x 1-3/4" x 5/8" and the rectangular sizes range from 2" x 3/4" x 5" to 2" x 1" x 8". Although oil-filled, we recommend using an oil such as our Stoning Oil or Polishing Lubricant and Diamond Thinner for best results as the use of oil increases the sharpening action and minimizes the clogging of the stones' surface.
