How to select the right taper-length drill bit for deep-hole drilling?
For deep-hole drilling, choose a bit with a parabolic flute design, like the CHICAGO-LATROBE 55252, to improve chip evacuation. A 135° split point reduces walking and thrust. Match the diameter (5/16") to your hole size and ensure the coating (TiN) suits the material—steel or stainless steel. Always use proper cutting fluid and pecking cycles.
