Frequently Asked Questions

What is the CHICAGO-LATROBE Jobber Length Drill Bit #8 used for?

This left-hand drill bit is designed for drilling holes in metal, particularly for removing broken fasteners or screws. The 118° point and high-speed steel construction make it suitable for general-purpose drilling in ferrous and non-ferrous materials. CHICAGO-LATROBE bits are commonly used in maintenance, repair, and production environments.

What are the specifications of the CHICAGO-LATROBE 44478 drill bit?

The CHICAGO-LATROBE 44478 is a #8 jobber-length drill bit with a 0.1990-inch diameter, 118° point angle, and left-hand spiral. It is made of high-speed steel (HSS) for durability. The manufacturer part number is 44478, and it is designed for left-hand rotation applications.
