Product Description

The OSG Thread Forming Tap (3/8"-24 UNF) is an oversized thread-forming tap with an H12 tolerance, modified bottoming chamfer, and TiCN-coated cobalt construction (MPN 1400138108). It is designed for forming internal threads without cutting, reducing chip evacuation issues in ductile materials.

Frequently Asked Questions

What is the OSG Thread Forming Tap 1400138108 used for?

This OSG thread forming tap is used to create internal threads in metal without cutting, ideal for ductile materials like aluminum and steel. The TiCN coating reduces friction and extends tool life. It is commonly applied in automotive, aerospace, and general manufacturing for precision threading.

What are the specifications of the OSG Thread Forming Tap 1400138108?

This tap has a 3/8"-24 UNF thread size, H12 tolerance, modified bottoming chamfer, and TiCN coated cobalt construction. The manufacturer part number is 1400138108. It is designed for forming threads in materials up to 850 °C hardness, with a 24 VDC compatible coating process.

Where to buy the OSG Thread Forming Tap 1400138108 worldwide?

You can source the OSG Thread Forming Tap 1400138108 through 3G Electric, a global industrial equipment distributor. We handle full logistics, customs clearance, and delivery to worldwide locations. Contact us for availability and lead time on this precision threading tool.

How to select the correct OSG thread forming tap for your application?

Select based on thread size (e.g., 3/8"-24 UNF), material hardness, and chamfer type. For blind holes, use a modified bottoming chamfer like this OSG tap. Ensure the H12 tolerance matches your thread class. Consult OSG's technical data for optimal speeds and lubrication.
