Chicago-Latrobe 46700 Jobber Drill Bit
This Chicago-Latrobe 46700 jobber-length drill bit is sized for precision drilling tasks in metalworking and maintenance applications. It suits professionals and technicians who require accurate hole placement in ferrous and non-ferrous materials. The split-point geometry helps reduce walking on hard surfaces.
Split Point with 135-Degree Angle
The 135-degree split point is the specification that determines suitability for hard materials such as stainless steel and cobalt alloys. This geometry centres the bit without a centre punch and lowers thrust requirements. The HAWA cobalt construction maintains hardness at elevated temperatures during extended use.
Wire Gauge 30 Compatibility
This bit drills a 0.1285-inch diameter hole matching wire gauge size 30, fitting standard jobber-length chucks and collets. It requires no coolant-through tooling and operates with conventional drill presses or hand drills. The straw-bronze finish identifies the cobalt grade and resists corrosion in shop environments.

Questions about this item
What does the 135-degree point angle do when drilling?
The 135-degree split point starts holes faster and reduces walking on hard materials.
How does the cobalt construction affect drilling performance?
Cobalt steel resists heat better than standard high-speed steel, extending bit life in tough alloys.
Will this number-30 bit fit a standard three-jaw chuck?
Yes, the 0.1285-inch shank fits any drill chuck that accepts wire-gauge sizes.
