Designed for aerospace materials, it delivers thread cutting with a spiral-point geometry that pushes chips ahead. 3G Electric sources this and thousands of other industrial consumables across 14 departments, with specialist depth in combustion, pumps, and controls to ensure you get the right tool for the job.

Frequently Asked Questions

What is an OSG spiral point tap used for?

An OSG spiral point tap is designed for threading blind or through holes in aerospace materials. Its spiral point pushes chips ahead, preventing clogging. The TiN-coated cobalt construction provides heat resistance and durability for high-strength alloys, making it ideal for precision thread forming in critical aerospace components.

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

This OSG tap has a 5/8"-18 UNF thread size, H9 / 2B-3B tolerance, 4 flutes, plug chamfer, and TiN-coated cobalt construction. The H9 pitch diameter tolerance ensures precise fit for 2B-3B class threads. Manufacturer part number is 1101518305. It is designed for aerospace materials requiring chip evacuation.
