Frequently Asked Questions

What is a Chicago-Latrobe #20 left-hand jobber drill bit used for?

A Chicago-Latrobe #20 left-hand jobber drill bit is used for drilling holes in metal, particularly for screw extraction or applications where reverse rotation prevents bit walking. It suits maintenance, toolmaking, and production environments requiring precise 0.1610-inch holes.

What are the specifications of the Chicago-Latrobe 44490 drill bit?

The Chicago-Latrobe 44490 is a #20 jobber length drill bit with a 0.1610-inch diameter, 118° point angle, and high-speed steel construction. It features a left-hand spiral for reverse-rotation drilling. This MPN 44490 bit is designed for general-purpose metal drilling.

Where to buy Chicago-Latrobe 44490 drill bits worldwide?

3G Electric supplies Chicago-Latrobe 44490 left-hand drill bits worldwide. As a global industrial sourcing partner, we handle full logistics, customs clearance, and delivery to your facility. Contact us for a quote on this MPN 44490 bit and other cutting tools.

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

To select a left-hand drill bit for screw extraction, match the bit diameter to the screw's minor thread diameter. A Chicago-Latrobe #20 (0.1610 inch) bit works for small fasteners. Use a slow speed with steady pressure to avoid breakage. Always wear safety glasses.
