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 production environments. Its spiral-point design pushes chips forward, preventing chip clogging and enabling faster tapping in materials like steel, aluminum, and cast iron. It is ideal for general-purpose threading operations.

What are the specifications of the CHICAGO-LATROBE 357322 tap?

The CHICAGO-LATROBE 357322 is a spiral point tap with size 5/16"-18 UNC, H3 / 2B tolerance, 3 flutes, and a plug chamfer. It is made of high-speed steel (HSS) for durability. The manufacturer part number is 357322, and it is designed for general-purpose through-hole tapping.

Where to buy CHICAGO-LATROBE taps in worldwide?

You can source CHICAGO-LATROBE taps worldwide through 3G Electric, a global industrial equipment distributor. We handle full logistics, customs clearance, and delivery to your location. Contact us for availability and lead time on the 357322 spiral point tap.

How to select the right CHICAGO-LATROBE tap for a job?

Select a CHICAGO-LATROBE tap based on thread size, material, and hole type. For through holes, a spiral point tap like the 357322 pushes chips forward. For blind holes, use a spiral flute tap. Match the tap tolerance (e.g., H3) to the required thread class (e.g., 2B) for proper fit.
