Frequently Asked Questions

What is a CHICAGO-LATROBE spiral point tap used for?

A CHICAGO-LATROBE spiral point tap is used for through-hole threading in metalworking. Its spiral point design pushes chips forward, preventing clogging and enabling faster production. It is ideal for general-purpose tapping in materials like steel, aluminum, and cast iron across machining, automotive, and industrial maintenance applications.

What are the specifications of the CHICAGO-LATROBE 280603 tap?

The CHICAGO-LATROBE 280603 is a spiral point tap with size 3/8"-16 UNC, H5 / 2B-3B tolerance, 3 flutes, and a plug chamfer. It is designed for through-hole threading and is suitable for general-purpose tapping in various materials. 3G Electric supplies this genuine CHICAGO-LATROBE part worldwide.

Where to buy CHICAGO-LATROBE taps in worldwide?

How to select the right spiral point tap for a job?

Select a spiral point tap based on thread size (e.g., 3/8"-16 UNC), material, and hole type—through holes require spiral point taps to eject chips forward. Match the chamfer (plug for general use) and tolerance class (H5 for 2B-3B fit). 3G Electric can help source the correct CHICAGO-LATROBE tap for your application.
