ABSTRACT:
A rotary carbide drill for drilling clean holes in aramid fiber composites is made from a cylindrical rod having a planar elliptical end surface. The drill has a longitudinally extending arcuate flute that becomes shallower as it progresses away from the end surface. The arcuate flute is generated with a diamond wheel or disc having a periphery with a semi-cylindrical cross-section in a manner so that each of two radial segments alternate as the lead cutting surfaces, providing essentially equal wear on the segments so that frequent dressing of the wheel is eliminated.
