Frequently Asked Questions
What is a Chicago-Latrobe #27 left-hand drill bit used for?
A Chicago-Latrobe #27 left-hand drill bit is used to remove broken bolts or screws by drilling in reverse, which often backs out the fastener. It is also used in applications where spindle rotation is left-handed, such as certain tapping machines or automotive repairs.

The Chicago-Latrobe 44497 is a #27 jobber-length drill bit with a 0.1440-inch diameter, 118° point angle, and made from high-speed steel (HSS). It features a left-hand spiral for reverse-rotation drilling. This bit is designed for general-purpose drilling in metals and plastics.

How to select the correct left-hand drill bit size for bolt removal?
To select the correct left-hand drill bit, choose a size slightly smaller than the broken bolt's minor diameter. For a #27 bit (0.1440 inch), it suits small fasteners. Always use cutting oil and slow speed to prevent bit breakage. Chicago-Latrobe HSS bits offer good durability for this task.
