Frequently Asked Questions

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

A CHICAGO-LATROBE spiral flute tap is used for threading blind holes in materials like steel and aluminum.

The CHICAGO-LATROBE 282302 is a 1/4\"-20 UNC spiral flute tap with a H3 / 2B tolerance, 3 flutes, and a bottoming chamfer. It is designed for threading blind holes to the bottom. The H3 limit ensures precise thread fit for general-purpose use in industrial machining.

How to select the right spiral flute tap for blind holes?

To select a spiral flute tap for blind holes, match the thread size (e.g., 1/4\"-20 UNC) and chamfer type—bottoming for threads to the hole bottom. Choose flute count (3 flutes for general use) and tolerance class (H3 for standard fit). CHICAGO-LATROBE taps are a reliable choice for consistent thread quality.
