Chicago-Latrobe Jobber Length Drill Bit, Drill Bit Size #40, Drill Bit Point Angle 135, Cobalt, Straw/Bronze

These drill bits can drill into harder materials than would be possible with standard cobalt jobber-length drill bits with a straw/bronze finish. They are used for drilling tough, high-tensile, and work-hardened materials like titanium. The bits have a straw/bronze finish that improves their wear resistance, and they have spiral flutes that evacuate chips as the bits drill into a workpiece.
