Frequently Asked Questions

What is an OSG spiral point tap used for?

An OSG spiral point tap is designed for through-hole threading in production environments. Its spiral-point geometry pushes chips forward, preventing chip congestion and enabling faster, cleaner threading in materials like steel and aluminum. This 1/2"-13 UNC tap is ideal for general-purpose machining across automotive, aerospace, and industrial manufacturing.

What are the specifications of the OSG 1232401 tap?

The OSG 1232401 is a 1/2"-13 UNC spiral point tap with 3 flutes, a plug chamfer, and black oxide high-speed steel construction. It has an H3 / 2B-3B tolerance class, ensuring precise thread fit for both 2B and 3B classes. This tap is suitable for through-hole threading in ferrous and non-ferrous materials.

Where to buy OSG taps in worldwide?

How to select the correct OSG tap for a job?

Select an OSG tap based on thread size (e.g., 1/2"-13 UNC), hole type (through vs. blind), material, and tolerance class. For through-holes, a spiral point tap like this 1232401 pushes chips forward. Match the H3 / 2B-3B class to your required thread fit. Consult OSG's technical data for material-specific speeds and feeds.
