Pertanyaan yang Sering Diajukan
What is an OSG spiral-flute STI tap used for?
An OSG spiral-flute STI tap is used to cut internal threads for screw thread inserts in materials that produce stringy chips, such as aluminum and low-carbon steel. The spiral-flute design evacuates chips upward, making it ideal for blind-hole applications. This tap is commonly used in automotive, aerospace, and general manufacturing.
What are the specifications of the OSG 8018400 STI tap?
The OSG 8018400 is a spiral-flute STI tap with a 1/2"-20 UNF thread, H3 / 2B-3B tolerance, 4 flutes, and a bottoming chamfer. It is designed for screw thread insert installation. The H3 / 2B-3B designation ensures precise thread fit for insert applications.

How to select the correct STI tap for a thread insert?
Select an STI tap that matches the insert's thread size and pitch, such as 1/2"-20 UNF. Choose a spiral-flute design for blind holes or a spiral-point design for through holes. The chamfer type—bottoming for threads near the hole bottom—and tolerance class (e.g., H3 / 2B-3B) must align with the insert manufacturer's recommendations.
