Cratex 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.
