Cratex® Small Wheels, 1"x1/4" - 88 Extra-Fine, Box of 100

These light green, extra-fine, 1" x 1/4", square-edge Cratex wheels are approximately 240 grit.   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. Ideal for work on jewelry, plastic parts, small castings and models.  Knife-edge wheels taper to a knife-edge for accessing slots, ribs and fine detail. Sold by the box (100 wheels per box). Max. operating speed: 25,000rpm.  Arbor hole: 1/16".   Made in Mexico.
