Frequently Asked Questions

What is an OSG spiral point tap used for?

An OSG spiral point tap is designed for through-hole threading in aluminum and non-ferrous materials. Its spiral-point geometry pushes chips forward, preventing clogging and ensuring clean threads. This tap is ideal for high-production CNC machining and manual tapping operations.

What are the specifications of the OSG 5/16"-18 UNC spiral point tap?

This OSG tap has a 5/16"-18 UNC thread, H3 / 2B-3B tolerance, 3 flutes, and a plug chamfer. It is designed for aluminum and non-ferrous materials. The spiral-point design pushes chips ahead, making it suitable for through-hole applications. OSG is a trusted brand in cutting tools.
