Product Description

OSG Spiral-Flute Extension Taps for Multiple Materials.

Frequently Asked Questions

What is the OSG extension tap 5/8"-11 UNC used for?

This OSG extension tap is designed for threading blind holes in multiple materials. Its spiral-flute design evacuates chips upward, making it ideal for deep-hole tapping in steel, stainless steel, and aluminum. The modified bottoming chamfer allows threading close to the bottom of the hole.

What are the specifications of the OSG extension tap MPN 1652504108?

The OSG extension tap MPN 1652504108 has a thread size of 5/8"-11 UNC, with an H5 pitch diameter tolerance for 2B-3B class fit. It features 3 flutes and a modified bottoming chamfer. The spiral-flute design is optimized for chip evacuation in blind-hole applications.

Where to buy OSG extension taps worldwide?

How to select the correct OSG extension tap for threading?

Select the OSG extension tap based on thread size, pitch, and hole type. For blind holes, use a bottoming chamfer tap like this 5/8"-11 UNC model. Match the H5 tolerance to your required thread class (2B or 3B). Ensure the tap length reaches the full thread depth needed.
