How to select the right screw-machine drill bit for deep-hole drilling?

For deep-hole drilling, choose a screw-machine length bit with a parabolic flute and fast spiral, like the WALTER #9 cobalt bit. The parabolic flute improves chip evacuation, while cobalt provides heat resistance. Ensure the point angle (130°) matches your material hardness for reduced thrust and better hole quality.
