Frequently Asked Questions

What is the CHICAGO-LATROBE #55 jobber length drill bit used for?

This left-hand high-speed steel drill bit is used for drilling holes in metal, wood, and plastic, particularly in applications where reverse rotation is needed to prevent screw jacking or to extract broken fasteners. It is common in automotive repair, toolmaking, and general maintenance.

What are the specifications of the CHICAGO-LATROBE 44525 drill bit?

The CHICAGO-LATROBE 44525 is a #55 jobber length drill bit with a 0.0520 inch diameter, 118° point angle, and made from high-speed steel (HSS). It features a left-hand spiral for reverse-rotation drilling. The manufacturer part number is 44525.

How to select the correct left-hand drill bit for extracting broken bolts?

Choose a left-hand bit like the CHICAGO-LATROBE #55 for small fasteners. Match the bit diameter to the bolt's minor thread diameter. Use a center punch to start the hole, then drill slowly with light pressure. The left-hand rotation often helps back out the broken fastener.
