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 spiral flute design pulls chips upward and out of the hole, preventing chip clogging and ensuring clean threads. It is ideal for production tapping in machining and manufacturing applications.

What are the specifications of the CHICAGO-LATROBE 282302 tap?

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.
