Frequently Asked Questions

What is an OSG spiral point tap used for?

An OSG spiral point tap is designed for through-hole threading in aerospace materials. Its spiral point pushes chips forward, preventing clogging. The TiN-coated cobalt construction provides wear resistance and heat dissipation, making it suitable for high-strength alloys common in aerospace manufacturing.

What are the specifications of the OSG 5/8"-18 UNF spiral point tap?

This OSG tap has a 5/8"-18 UNF thread, H3 / 2B-3B tolerance, 4 flutes, and a plug chamfer. It is TiN coated cobalt, part number 1101517805. The H3 / 2B-3B designation ensures precise fit for class 2B or 3B threaded holes in aerospace materials.

Where to buy OSG taps in worldwide?

3G Electric supplies OSG taps worldwide, handling logistics, customs, and delivery. As a global industrial solutions provider, we source genuine OSG cutting tools like the 5/8"-18 UNF spiral point tap. Contact us for pricing and lead time on this aerospace-grade threading tool.

How to select the right OSG tap for aerospace materials?

Select an OSG tap with TiN coating and cobalt substrate for heat resistance in aerospace alloys. Choose spiral point design for through holes to eject chips forward. Verify thread size (e.g., 5/8"-18 UNF) and tolerance class (H3 / 2B-3B) match your hole requirements. Consult OSG technical data for material-specific speeds and feeds.
