Frequently Asked Questions

What is a Chicago-Latrobe #28 left-hand drill bit used for?

A Chicago-Latrobe #28 left-hand drill bit is used for drilling holes in metal, particularly for extracting broken bolts or screws. The left-hand rotation prevents the fastener from tightening further, making it essential for automotive and industrial maintenance applications.

What are the specifications of the Chicago-Latrobe 44498 drill bit?

The Chicago-Latrobe 44498 is a #28 jobber-length drill bit with a 0.1405-inch diameter, 118° point angle, and high-speed steel construction. It features a left-hand spiral for reverse-rotation drilling. The manufacturer part number is 44498.

Where to buy Chicago-Latrobe 44498 drill bits worldwide?

You can source Chicago-Latrobe 44498 drill bits through 3G Electric, a global industrial equipment distributor. We handle full logistics, customs clearance, and delivery to worldwide destinations. Contact us for availability and lead times.

How to select the correct left-hand drill bit for bolt extraction?

To select a left-hand drill bit for bolt extraction, match the bit diameter to the broken fastener's minor thread diameter. Use a #28 size like the Chicago-Latrobe 44498 for small fasteners. Ensure the bit is high-speed steel for durability and a 118° point for general-purpose drilling.
