Cratex is a tough, resilient, rubberized abrasive that utilizes silicon carbide as the abrasive grain in a standard bond of premium grade, oil-resistant chemical rubber. Its unique cushioned action allows the abrasive grains to cut freely, smoothly and softly without gouging or digging into the work surface.
  • Clean and polish to remove surface deposits.
  • Remove rough surfaces to improve performance, appearance and cleanliness.
  • Ideal for work on jewelry, plastic parts, small castings and models.

Cratex Large Wheels are available in 8 sizes and 4 color-coded grits: Coarse, Medium, Fine, and Extra-Fine.
