- Cobalt steel tools are similar to high-speed steel, but with more cobalt for improved performance when cutting harder metals such as stainless steel or nickel alloys
- High red hardness of cobalt permits speeds 30 percent greater than HSS drills
- Round shanks allow use with a wide variety of toolholding systems
- When run in a counterclockwise direction (right-hand cut) spiral fluted tools evacuate chips up and out of the cut to reduce clogging
- 21 jobber length drill bits ranging in size from 1/16" to 1/4" in 1/64" increments and from 9/32" to 1/2" in 1/32" increments
