Product Description

OSG Oversized Thread-Forming Taps.

Frequently Asked Questions

What is an OSG thread forming tap used for?

An OSG thread forming tap creates internal threads by displacing material rather than cutting it, producing stronger, burr-free threads in ductile materials like aluminum and steel. This 1/2"-20 UNF plug chamfer tap is ideal for high-production CNC machining and automotive applications.

What are the specifications of the OSG 1/2"-20 UNF thread forming tap?

This OSG tap has a 1/2"-20 UNF thread size, H11 tolerance, plug chamfer, and black oxide cobalt finish. The manufacturer part number is 1400146101. It is designed for forming threads in materials up to 850 °C hardness, with a 24 VDC compatible coating for extended tool life.

Where to buy OSG thread forming taps worldwide?

3G Electric supplies OSG thread forming taps like the 1/2"-20 UNF model (MPN 1400146101) to customers worldwide. We handle full logistics, customs clearance, and delivery to your facility. Contact us for pricing and lead time on this precision threading tool.

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

Select an OSG thread forming tap based on thread size (e.g., 1/2"-20 UNF), material hardness, and chamfer type. Plug chamfer taps suit through holes, while bottoming chamfer works for blind holes. For ductile materials like aluminum, use cobalt or HSS-E taps with black oxide coating for reduced friction.
