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 ahead, reducing clogging and enabling faster production. It is ideal for general-purpose tapping in steel, aluminum, and other materials across machining, automotive, and industrial maintenance applications.

What are the specifications of the CHICAGO-LATROBE #5-40 UNC tap?

The CHICAGO-LATROBE spiral point tap has a #5-40 UNC thread, H2 / 2B tolerance, 2 flutes, and a plug chamfer. It is designed for through-hole tapping and is made from high-speed steel for durability. The manufacturer part number is 356403.

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

Select a spiral point tap based on thread size, material, and hole type. For through holes, a spiral point tap pushes chips forward. Match the tap's thread class (e.g., H2/2B) to your required fit. CHICAGO-LATROBE taps are suitable for general-purpose tapping in steel and non-ferrous metals. Consult a technical datasheet for speed and feed recommendations.
