Product Description

OSG Spiral-Point Taps for Steel & Stainless Steel.

Frequently Asked Questions

What is an OSG spiral point tap used for?

An OSG spiral point tap is designed for threading through-holes in steel and stainless steel. Its spiral point pushes chips forward, preventing clogging and enabling faster, cleaner threading in production environments.

What are the specifications of the OSG 1731508 tap?

The OSG 1731508 is a 1/2"-20 UNF spiral point tap with a H3 / 2B-3B tolerance, 3 flutes, and a plug chamfer. It is designed for threading steel and stainless steel, ensuring precise fit and thread quality.

Where to buy OSG taps in worldwide?

3G Electric supplies OSG taps worldwide, handling full logistics and customs clearance. As a global industrial sourcing partner, we provide genuine OSG cutting tools like the 1731508 spiral point tap to customers across industries.

How to select the right tap for steel threading?

For steel threading, choose a spiral point tap like the OSG 1731508 for through-holes. Match thread size (1/2"-20 UNF), chamfer type (plug), and tolerance (H3 / 2B-3B) to your application. Consult OSG's technical data for material-specific speeds and feeds.
