Frequently Asked Questions

What is the CHICAGO-LATROBE #66 jobber length drill bit used for?

This left-hand high-speed steel drill bit is used for drilling small-diameter holes in metal, wood, and plastic. The #66 size (0.0330 inch) and 118° point make it ideal for precision work, especially in applications where left-hand rotation prevents screw-back or is required for reverse-spindle operations.

What are the specifications of the CHICAGO-LATROBE 44536 drill bit?

The CHICAGO-LATROBE 44536 is a #66 jobber length drill bit with a 0.0330 inch diameter, 118° point angle, and left-hand spiral. It is made from high-speed steel (HSS) for durability. The manufacturer part number is 44536, and it is designed for general-purpose drilling in ferrous and non-ferrous materials.

How to select the correct left-hand drill bit for reverse drilling?

Select a left-hand drill bit like the CHICAGO-LATROBE #66 when you need to drill in reverse rotation, such as for extracting broken fasteners or in left-hand threaded applications. Match the diameter (0.0330 inch) to your hole size, and ensure the shank fits your chuck. Use cutting fluid for metal to extend tool life.
