Frequently Asked Questions
What is the OSG #6-32 UNC extension tap used for?
The OSG #6-32 UNC extension tap is designed for threading blind or deep holes in multiple materials. Its spiral-flute design and modified bottoming chamfer help evacuate chips upward, making it suitable for production tapping in steel, aluminum, and cast iron where standard taps cannot reach.

The OSG 1652500608 is a #6-32 UNC spiral-flute extension tap with a H3 / 2B-3B thread limit. It has 2 flutes and a modified bottoming chamfer. The H3 tolerance ensures precise thread fit for 2B-3B classes, and the extended length allows access to recessed features.
