Frequently Asked Questions

What is the OSG spiral flute tap used for?

The OSG spiral flute tap is designed for threading blind holes in materials such as steel and stainless steel. Its spiral flute design evacuates chips upward, preventing clogging and ensuring clean threads. The TiCN coating reduces friction and extends tool life, making it suitable for general-purpose machining in automotive, aerospace, and industrial manufacturing.

What are the specifications of the OSG spiral flute tap?

This OSG tap has a 1/4"-20 UNC thread size, H5 / 2B-3B tolerance, 3 flutes, and a plug chamfer. It is made of TiCN coated high speed steel. The manufacturer part number is 5003408. These specs ensure precise threading in blind holes for general-purpose applications.
