Product Description

The OSG Spiral Point Tap (1/4"-20 UNC, MPN 1220001) is a general-purpose spiral-point tap with a plug chamfer, black oxide high-speed steel construction, and H1 / 2B-3B thread class. It features 2 flutes and is designed for through-hole tapping applications.

Frequently Asked Questions

What is an OSG spiral point tap used for?

An OSG spiral point tap is used for through-hole threading in metalworking. Its spiral point design pushes chips ahead, preventing clogging. It is ideal for high-speed production tapping in steel, aluminum, and other materials, ensuring clean threads in applications like automotive and general manufacturing.

What are the specifications of the OSG 1/4"-20 UNC spiral point tap?

This OSG tap has a 1/4"-20 UNC thread size, H1 / 2B-3B tolerance, 2 flutes, and a plug chamfer. It is made of black oxide high-speed steel (MPN 1220001). The H1 limit ensures precise thread fit for general-purpose tapping in through holes.

Where to buy OSG taps in worldwide?

How to select the right spiral point tap for through holes?

Select a spiral point tap based on thread size, material, and hole type. For through holes, use a plug or bottoming chamfer. Match the tap tolerance (e.g., H1) to the required thread class (2B). OSG taps are suitable for steel and aluminum; consult a technical datasheet for speeds and feeds.
