OSG General Purpose Spiral-Point Taps.

Frequently Asked Questions

What is an OSG spiral point tap used for?

An OSG spiral point tap is used for through-hole threading in metals and alloys. Its spiral point design pushes chips forward, preventing clogging and ensuring clean threads. It is ideal for high-speed production tapping in automotive, aerospace, and general manufacturing applications.

What are the specifications of the OSG 1/4"-28 UNF spiral point tap?

This OSG tap has a 1/4"-28 UNF thread size, H4 / 2B-3B tolerance, 3 flutes, and a plug chamfer. It is designed for general purpose through-hole tapping. The H4 limit ensures precise thread fit for 2B-3B class threads in materials like steel and aluminum.

Where to buy OSG taps in worldwide?

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

How to select the right OSG tap for through-hole threading?

For through-hole threading, choose a spiral point tap like this OSG 1/4"-28 UNF model. Match the thread size, pitch, and tolerance class (H4 / 2B-3B) to your application. Consider material hardness and tap coating for extended tool life. Consult OSG's technical data for optimal speeds and feeds.
