Product Description

OSG General Purpose 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 threads in ductile materials like aluminum and steel. It is ideal for high-speed production in automotive, aerospace, and general manufacturing applications.

What are the specifications of the OSG 1/4"-28 UNF thread forming tap?

This OSG tap has a 1/4"-28 UNF thread size, H9 tolerance, plug chamfer, and TiN coated cobalt construction. The TiN coating reduces friction and extends tool life. It is designed for general purpose thread forming in materials up to 850 °C hardness.

Where to buy OSG thread forming taps worldwide?

3G Electric supplies OSG thread forming taps worldwide, handling full logistics and customs clearance. As a global industrial solutions provider, we source genuine OSG tools like the 1/4"-28 UNF TiN coated tap and deliver to your facility. Contact us for pricing and lead time.

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

Select a thread forming tap based on thread size (e.g., 1/4"-28 UNF), material type, and tolerance class (H9 for tight fits). Use TiN coated taps for ferrous metals and uncoated for non-ferrous. Ensure the tap chamfer matches hole depth—plug chamfer suits blind holes. Consult OSG's technical data for speeds and feeds.
