Frequently Asked Questions

What is a left-hand cobalt jobber-length drill bit used for?

A left-hand cobalt jobber-length drill bit is used for drilling in reverse rotation, typically to extract broken fasteners or to prevent bit walking in applications where the drill spindle rotates counterclockwise. The 135° split point reduces walking and improves cutting efficiency.

What are the specifications of the CHICAGO-LATROBE 46510 drill bit?

The CHICAGO-LATROBE 46510 is a 5/32" (0.1563 inch) left-hand jobber-length drill bit with a straw/bronze cobalt finish and a 135° split point. It is designed for drilling ferrous metals and hardened materials where left-hand rotation is required.

Where to buy CHICAGO-LATROBE 46510 drill bits worldwide?

3G Electric supplies CHICAGO-LATROBE 46510 left-hand cobalt drill bits worldwide. We handle full logistics, customs clearance, and delivery to your site. Contact us for pricing and lead time on this and other industrial cutting tools across 14 departments.

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

Select a left-hand drill bit like the CHICAGO-LATROBE 46510 that matches the broken fastener's diameter. Use a 135° split point to reduce walking. Apply cutting oil and run the drill in reverse at low speed. Cobalt construction handles hardened steel better than HSS.
