Frequently Asked Questions

What is a CHICAGO-LATROBE left-hand cobalt jobber drill bit used for?

A CHICAGO-LATROBE left-hand cobalt jobber drill bit is used for drilling into hardened metals and for screw-extraction applications where reverse rotation prevents bit binding. The 135° split point reduces walking on contact, making it ideal for maintenance and toolroom work.

What are the specifications of the CHICAGO-LATROBE 46504 drill bit?

The CHICAGO-LATROBE 46504 is a 1/16" (0.0625 in) left-hand jobber-length drill bit with a straw/bronze cobalt finish and a 135° split point. It is designed for drilling ferrous metals and is commonly used in industrial machining and repair applications.

Where to buy CHICAGO-LATROBE drill bits worldwide?

How to select the correct left-hand drill bit for screw extraction?

To select a left-hand drill bit for screw extraction, match the bit diameter to the screw head size. A cobalt grade like CHICAGO-LATROBE's straw/bronze finish provides heat resistance for hardened fasteners. Use a 135° split point to prevent walking and ensure clean entry.
