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 ahead, preventing clogging and enabling faster, cleaner threads in materials like steel and aluminum. This 1/4"-28 UNF tap is ideal for high-speed tapping operations.

What are the specifications of the CHICAGO-LATROBE 918937 tap?

The CHICAGO-LATROBE 918937 is a 1/4"-28 UNF spiral point tap with H3 / 2B tolerance, 2 flutes, and a plug chamfer. It is made of high-speed steel for durability. This design is optimized for through-hole threading in production applications.
