Frequently Asked Questions

What is the CHICAGO-LATROBE 51820 screw machine drill bit used for?

The CHICAGO-LATROBE 51820 is a general-purpose cobalt screw-machine length drill bit used for precision drilling in metalworking applications. Its 135° split point reduces walking and requires less thrust, making it ideal for CNC lathes and automatic screw machines in industrial manufacturing.

What are the specifications of the CHICAGO-LATROBE 51820 drill bit?

The CHICAGO-LATROBE 51820 is a 23/64" (0.3594") screw-machine length drill bit with a 135° split point and TiN-coated cobalt construction. The TiN coating increases lubricity and extends tool life in ferrous materials. It is designed for general-purpose drilling in production environments.

Where to buy CHICAGO-LATROBE 51820 drill bits worldwide?

How to select the correct screw machine drill bit for CNC applications?

Select a screw machine drill bit like the CHICAGO-LATROBE 51820 based on hole diameter (23/64"), material (cobalt for heat resistance), and coating (TiN for ferrous metals). The 135° split point is preferred for CNC because it self-centers and reduces thrust. Match the flute length to your drilling depth.
