Frequently Asked Questions

What is the CHICAGO-LATROBE #66 jobber length drill bit used for?

This TiN-coated HSS drill bit is designed for general-purpose drilling in metals, plastics, and wood. The #66 wire-gauge size (0.0330 inch) suits precision small-hole applications in machining, electrical, and instrumentation work.

What are the specifications of the CHICAGO-LATROBE 70166 drill bit?

The CHICAGO-LATROBE 70166 is a #66 jobber length drill bit with a 118° point angle, made from high-speed steel with a titanium nitride (TiN) coating. The drill diameter is 0.0330 inch. It is a general-purpose tool for small-hole drilling.

Where to buy CHICAGO-LATROBE drill bits worldwide?

3G Electric supplies CHICAGO-LATROBE drill bits to customers worldwide. We handle full logistics, customs clearance, and delivery for global orders. Contact us to source this #66 TiN-coated HSS bit or other industrial tooling needs.

How to select the right jobber length drill bit for small holes?

For small holes like #66 (0.0330 inch), choose a jobber length bit with a 118° point for general materials. TiN coating reduces friction and extends tool life in ferrous metals. Match the bit material to your workpiece—HSS works for most metals and plastics.
