Frequently Asked Questions

What is the CHICAGO-LATROBE Extra Long Drill Bit 50749 used for?

This extra-long drill bit is designed for deep-hole drilling in metal, wood, and plastic. Its 12" overall length reaches recessed or hard-to-access areas. The 118° notched point reduces walking on curved surfaces, making it suitable for maintenance, fabrication, and tool-and-die work.

What are the specifications of the CHICAGO-LATROBE 50749 drill bit?

The CHICAGO-LATROBE 50749 is a 27/64" (0.4219") black oxide high-speed steel extra-long drill bit with a 12" overall length and a 118° notched point. The black oxide finish provides lubricity and corrosion resistance. It is manufactured under part number 50749.

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

Choose a bit with overall length exceeding your hole depth. For steel, use high-speed steel (HSS) with a black oxide finish. The 118° point is standard for general drilling; a notched point helps prevent walking. Match the shank diameter to your chuck and ensure adequate machine rigidity.
