Frequently Asked Questions

What is a CHICAGO-LATROBE Extra Long Drill Bit used for?

This CHICAGO-LATROBE extra long drill bit is designed for deep-hole drilling in metal, wood, and plastic where standard-length bits cannot reach. The 12" overall length and 118° notched point provide precise entry and chip evacuation in industrial machining, maintenance, and fabrication applications.

What are the specifications of the CHICAGO-LATROBE 50466 drill bit?

The CHICAGO-LATROBE 50466 is a 9/64" diameter extra long drill bit with 12" overall length, 118° notched point, and black oxide finish on high-speed steel. The drill diameter is 0.1406 inches. It is designed for extended reach in tough materials.

Where to buy CHICAGO-LATROBE extra long drill bits worldwide?

How to select the right extra long drill bit for deep hole drilling?

Choose a bit with overall length exceeding your hole depth, like the CHICAGO-LATROBE 12" bit. Match diameter (9/64") to your hole size. For steel, a 118° notched point reduces walking. Black oxide HSS provides heat resistance. Ensure your drill press or machine has sufficient quill travel.
