Hertel Screw Machine Length Drill Bit, 39/64" Dia, Cobalt, 135 Degree, Straw Finish, 4-1/4" OAL, 2-3/4" Flute Length, Regular Spiral Flute, Right Hand Cut

The Hertel 39/64" (0.6094) Screw Machine Length Drill Bit delivers precision and durability for demanding drilling applications. Featuring a 135-degree split point design that reduces thrust requirements and prevents walking, this cobalt drill bit offers superior heat and wear resistance when working with tough materials. The straw/oxide gold finish provides additional protection against corrosion while enhancing surface hardness. With a compact 4-1/4" overall length and 2-3/4" flute length, this right-hand cut bit with regular spiral flutes is optimized for screw machine operations where controlled chip evacuation is essential. The premium cobalt construction maintains edge retention even during extended use in hardened steels and other challenging workpieces. Ideal for manufacturing environments requiring consistent hole quality and extended tool life.
