Frequently Asked Questions

What is a CHICAGO-LATROBE taper length drill bit used for?

A CHICAGO-LATROBE taper length drill bit is used for deep-hole drilling in metalworking and industrial machining. Its parabolic flute design clears chips efficiently, while the 135° split point reduces walking and thrust. It suits applications in automotive, aerospace, and general fabrication where precision and chip evacuation are critical.

What are the specifications of the CHICAGO-LATROBE 55263 drill bit?

The CHICAGO-LATROBE 55263 is a 31/64" (0.4844 inch) taper length drill bit with a 135° split point. It features TiN-coated high-speed steel and a parabolic flute for chip clearing. This combination provides wear resistance and efficient drilling in steel and alloys.

How to select the right taper length drill bit for deep hole drilling?

Select a taper length drill bit based on hole depth, material, and required finish. For deep holes in steel, choose a TiN-coated HSS bit with a 135° split point and parabolic flute, like the CHICAGO-LATROBE 55263. Ensure the shank fits your machine's taper and that coolant delivery matches the application.
