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 ahead, preventing clogging. The TiN-coated cobalt construction provides heat resistance and wear life for demanding applications like aircraft component manufacturing.

What are the specifications of the OSG 1/2"-20 UNF spiral point tap?

This OSG tap has a 1/2"-20 UNF thread, H7 / 2B-3B tolerance, 3 flutes, and a plug chamfer. It is made of TiN-coated cobalt for durability. The manufacturer part number is 1101505205. These specs ensure precise threading in aerospace-grade materials.

Where to buy OSG taps in worldwide?
