Frequently Asked Questions

What is OSG spiral point tap used for?

OSG spiral point taps are designed for threading blind or through holes in steel and stainless steel. The spiral point pushes chips ahead, reducing clogging and breakage. This 1/2"-13 UNC plug chamfer tap is ideal for production tapping in automotive, aerospace, and general manufacturing.

What are the specifications of OSG 1/2"-13 UNC spiral point tap?

This OSG tap has a 1/2"-13 UNC thread, H3 / 2B-3B tolerance, 3 flutes, and a plug chamfer. It is designed for steel and stainless steel. The spiral point geometry directs chips forward for efficient through-hole tapping. Part number 1101701408.
