CRATEX RUBBERISED ABRASIVE POINTS
Cratex Shaped points are made in both cylinder and bullet shapes...for smoothing and polishing hard to reach surfaces...grooves, ball corners, holes, clasps, spirals, flutes, and edges. They are widely used for polishing molds, dies, patterns and light castings; for cleaning contact points, solder spots and for relieving stress, micro-deburring, and damaskeening.
The resilient rubber binder cushions the aluminum oxide abrasive and bridges the gap between grinding and polishing.
