Frequently Asked Questions

What is an OSG spiral point tap used for?

An OSG spiral point tap is used for through-hole threading in metals. Its spiral-point design pushes chips forward, preventing clogging and enabling faster, cleaner threads in production machining, automotive, and general manufacturing applications.

What are the specifications of the OSG 2842601 tap?

The OSG 2842601 is a spiral point tap with 1/2"-20 UNF thread, H5 tolerance, 3-flute design, and plug chamfer. It is rated for 2B-3B class fit. This general-purpose tap is suitable for through-hole threading in steel and other materials.

Where to buy OSG taps in worldwide?

How to select the right OSG tap for a job?

Select an OSG tap based on thread size, pitch, material, and hole type. For through holes, a spiral point tap like the 2842601 is ideal. Match the tap tolerance (e.g., H5) to the required thread class (2B-3B). Consult OSG's technical data for material-specific speeds and feeds.
