Frequently Asked Questions

What is the CHICAGO-LATROBE Extra Long Drill Bit 50473 used for?

This extra-long drill bit is designed for deep-hole drilling in metal, wood, and plastic. Its 10" overall length and 118° notched point allow access to recessed areas and reduce walking on curved surfaces. Common applications include maintenance, tool-and-die work, and production environments requiring extended reach.

What are the specifications of the CHICAGO-LATROBE 50473 drill bit?

The CHICAGO-LATROBE 50473 is a black oxide high-speed steel (HSS) extra-long drill bit with a 11/64" (0.1719") diameter, 10" overall length, and a 118° notched point. The black oxide finish provides increased lubricity and corrosion resistance. It is manufactured under part number 50473.

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

Select based on material, hole depth, and required finish. For steel, use HSS with a 118° point; for harder alloys, consider cobalt or carbide. Ensure overall length exceeds hole depth by at least 1". The CHICAGO-LATROBE 50473's black oxide finish reduces friction. Always match drill speed and feed rate to the material being drilled.
