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"-20 UNC tap is common in automotive, aerospace, and general machining applications.

What are the specifications of the CHICAGO-LATROBE 282306 tap?

The CHICAGO-LATROBE 282306 is a 1/4"-20 UNC spiral point tap with a H3 / 2B tolerance, 3-flute design, and plug chamfer. It is made from high-speed steel (HSS) for durability in general-purpose threading. The MPN is 282306, and it is designed for through-hole applications.

Where to buy CHICAGO-LATROBE taps in worldwide?
