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.

What are the specifications of the OSG 1652500608 extension tap?

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.

Where to buy OSG extension taps worldwide?

You can source the OSG #6-32 UNC extension tap through 3G Electric, a global industrial equipment distributor. We handle full logistics, customs clearance, and delivery to worldwide destinations. Contact us for availability and lead time on this and other OSG tooling.

How to select the correct OSG extension tap for a job?

Select the OSG extension tap based on thread size (#6-32 UNC), required thread class (H3 / 2B-3B), and hole depth. The spiral-flute design suits materials that produce stringy chips. For blind holes, use a modified bottoming chamfer. Always match the tap to the material and machine rigidity.
