Product Description

OSG Spiral-Point Taps for Aerospace Materials.

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 extending tool life.

What are the specifications of the OSG spiral point tap 1101516805?

The OSG spiral point tap MPN 1101516805 has a #12-28 UNF thread size, H10 tolerance, 3-flute design, plug chamfer, and TiN coating on cobalt substrate. It is engineered for aerospace-grade materials, ensuring precise thread formation and durability under demanding conditions.

Where to buy OSG spiral point taps in worldwide?

You can source OSG spiral point taps worldwide through 3G Electric, a global industrial equipment distributor. We handle full logistics, customs clearance, and delivery to your location, ensuring reliable supply for your threading needs without stock-status claims.

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

Select an OSG spiral point tap based on thread size, tolerance, and coating. For aerospace materials, choose TiN-coated cobalt taps like the #12-28 UNF H10 model to resist wear. Ensure the chamfer type (plug for through-holes) matches your application for optimal chip evacuation.
