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 to drill holes in hard metals and for removing broken bolts or screws. The left-hand rotation prevents the fastener from tightening further during extraction. CHICAGO-LATROBE's 3/8" bit with a 135° split point reduces walking and improves cutting efficiency.

What are the specifications of the CHICAGO-LATROBE 46524 drill bit?

The CHICAGO-LATROBE 46524 is a 3/8" left-hand cobalt jobber-length drill bit with a 135° split point. It has a straw/bronze finish and is designed for drilling hard materials. The cobalt alloy provides heat resistance and extended tool life in demanding applications.

Where to buy CHICAGO-LATROBE 46524 drill bits worldwide?

3G Electric supplies CHICAGO-LATROBE 46524 left-hand cobalt drill bits worldwide. We handle full logistics, customs clearance, and delivery to your facility. As a global industrial solutions provider, we source genuine CHICAGO-LATROBE tooling and support procurement across 14 industrial departments.

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

Select a left-hand drill bit that matches the broken fastener's diameter, such as the CHICAGO-LATROBE 3/8" cobalt bit. Use a 135° split point to prevent walking on curved surfaces. Cobalt construction withstands the heat generated during extraction. Always start at low speed with steady pressure to avoid bit breakage.
