Chicago-Latrobe 45796 135 Degree Heavy-Duty Jobber Length Drill Bit

Chicago-Latrobe 45796 Heavy-Duty Drill Bit

This Chicago-Latrobe 45796 is a heavy-duty jobber length drill bit built for demanding drilling tasks. It features a 135 degree split point design that enables precise starting without wandering. The bit is manufactured from High Speed Steel with a black oxide finish for durability. It suits professionals and workshops requiring reliable performance in metalworking applications.

Ideal for metal drilling with split point precision

This drill bit suits machinists and fabricators who need accurate hole placement in steel and other alloys. The split point geometry reduces thrust requirements and improves chip ejection during operation. Buyers needing coolant-through capability or specialized coating systems for extreme heat resistance should look at alternative tooling options. The non-coolant design limits suitability for deep-hole or high-volume production runs.

Letter size Z handles medium-duty metalwork

The decimal equivalent of .4130 inches provides capacity for standard fastening and clearance holes in structural and maintenance work. High Speed Steel construction offers sufficient wear resistance for general-purpose drilling in mild to medium carbon steels. The material reaches its limit in hardened alloys or abrasive composites where carbide-tipped or cobalt tools become necessary. Black oxide finish aids lubricity but does not substitute for dedicated cutting fluids in difficult materials.
