Frequently Asked Questions

What is OSG Thread Forming Tap #1-64 UNC used for?

This OSG thread-forming tap creates internal threads in multiple materials without cutting, which eliminates chips and produces stronger threads. It is ideal for ductile materials like aluminum, brass, and low-carbon steel in precision machining and production environments.

What are the specifications of OSG Thread Forming Tap 1625001642?

This OSG tap is #1-64 UNC with a H2 / 2B-3B tolerance, modified bottoming chamfer, and V coated cobalt construction. The V coating reduces friction and extends tool life. It is designed for high-performance thread forming in multiple materials.

How to select the right OSG thread forming tap for my application?

Select based on thread size, material, and hole type. For through holes, use a plug or bottoming chamfer; for blind holes, a modified bottoming chamfer like this OSG tap works. Ensure the H limit matches your required thread class (2B-3B). Always match coating to material for optimal performance.
