R38 threaded cross

R38 threaded cross bit with tungsten carbide material

This R38 threaded series of drill bits includes both cross-type and X-type designs. The cross bit is easier to sharpen because the included angles on all four sides are equal. The X-type bit is suitable for rock formations that are very prone to wear and cracking.
