How to select the correct jobber length drill bit for hardened steel?

For hardened steel, select a solid carbide drill bit with a TiN coating for heat resistance and wear protection. A 118° 4-facet point improves centering and reduces thrust. Match the diameter to your hole size (e.g., #77 = 0.0180"). Use rigid setup and proper coolant to extend tool life.
