Product Details

The 4 groove design of these special Busch 4203 3/32" mounted carbide twist drills works best with softer materials, so these carbide drills are recommended for cutting coral and pearls. These drills will last the longest when used in a drill press, as like any drill, breakage will occur with excess leverage or canting. If using by free-hand, the recommended speed is 5,000 to 9000 rpm, and the use of a starting guide hole will help. For use in a press, the recommended speed is from 8,000 to 14,000 rpm. Not for use with glass, ceramics and gem stones. These Carbide twist drills are sold by the piece.
