Frequently Asked Questions

What is the OSG spiral point tap #12-28 UNF used for?

This OSG spiral point tap is designed for threading #12-28 UNF holes in aerospace materials. Its TiN-coated cobalt construction and plug chamfer make it suitable for through-hole tapping in high-strength alloys, reducing chip congestion and improving thread finish.

What are the specifications of the OSG spiral point tap 1101516605?

The OSG spiral point tap MPN 1101516605 has a #12-28 UNF thread size, H8 / 2B tolerance, 3 flutes, and a plug chamfer. It features a TiN coating on cobalt substrate, designed for aerospace materials. The H8 / 2B class ensures precise thread fit for critical applications.

Where to buy OSG spiral point taps worldwide?

You can source OSG spiral point taps like the 1101516605 through 3G Electric, a global industrial equipment distributor. We handle full logistics, customs clearance, and delivery to worldwide destinations, ensuring you receive genuine OSG tooling for your aerospace threading needs.

How to select the correct OSG spiral point tap for aerospace materials?

Select an OSG spiral point tap based on thread size, tolerance class (e.g., H8 / 2B), and coating. For aerospace materials, choose TiN-coated cobalt taps like the #12-28 UNF model. Ensure the chamfer type (plug) matches your hole configuration—through holes benefit from spiral point geometry to push chips forward.
