Frequently Asked Questions

What is an OSG spiral point tap used for?

An OSG spiral point tap is designed for through-hole threading in metals. Its spiral point pushes chips ahead, preventing clogging and ensuring clean threads. It is commonly used in automotive, aerospace, and general machining applications where efficient chip evacuation is critical.

What are the specifications of the OSG 2856800 tap?

The OSG 2856800 is a 3/8"-24 UNF spiral point tap with an H11 tolerance, 3 flutes, and a plug chamfer. It is an oversized tap for producing threads slightly larger than standard, ideal for applications requiring a looser fit or coating allowance.

How to select the correct 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 2856800 is ideal. Match the tap tolerance (e.g., H11) to your required thread class. Consult OSG's technical data for material-specific speeds and feeds.
