Chicago-Latrobe 41792 135° Jobber Drill

This Chicago-Latrobe 41792 drill bit is a heavy-duty jobber-length tool built from high-speed steel with a TiN coating. Its 135-degree split point is designed to reduce walking and start holes cleanly in metal. The bit measures 0.3770 inches decimal equivalent, corresponding to letter size V. It is a non-coolant-through design with zero coolant holes.

Suited for Production Drilling in Metal

Machinists and maintenance technicians who need a durable, general-purpose bit for drilling steel and other ferrous materials will find this tool fits the task. The TiN coating adds wear resistance for longer life in repetitive operations. Buyers who require through-coolant capability for deep-hole chip evacuation should look at a different style of bit.

135-Degree Split Point Geometry

The 135-degree split point is the specification that determines how this bit behaves on contact. It self-centres without a centre punch and reduces thrust force compared to standard point angles. This geometry makes the bit suitable for harder materials and portable drilling where precision starting matters.
