Product Description

OSG Spiral-Flute Extension Taps for Multiple Materials.

Frequently Asked Questions

What is an OSG extension tap used for?

An OSG extension tap is used for threading blind holes or hard-to-reach areas in multiple materials. Its extended reach allows tapping deep cavities or offset positions where standard taps cannot access, common in machining and maintenance applications.

What are the specifications of the OSG 3/4"-16 UNF extension tap?

This OSG extension tap has a 3/4"-16 UNF thread size, H5 tolerance for 2B-3B class fit, 4 flutes, and a modified bottoming chamfer. It is a spiral-flute design for chip evacuation in multiple materials. The MPN is 1652504708.

Where to buy OSG extension taps worldwide?

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

Select an OSG extension tap based on thread size (e.g., 3/4"-16 UNF), material type, hole depth, and chamfer style. For blind holes, use a modified bottoming chamfer. Ensure the tap's flute design matches chip evacuation needs. Consult OSG's technical data for optimal performance.
