Frequently Asked Questions

What is the OSG spiral point tap #8-32 UNC used for?

The OSG spiral point tap #8-32 UNC is used for threading blind or through holes in ferrous and non-ferrous materials. Its spiral point design pushes chips ahead, reducing clogging and breakage. Common applications include automotive, aerospace, and general manufacturing where precise internal threads are required.

What are the specifications of the OSG tap MPN 1212901?

The OSG tap MPN 1212901 is a #8-32 UNC spiral point tap with a H3 / 2B-3B tolerance class. It has 2 flutes and a bottoming chamfer, designed for general purpose threading. The H3 limit ensures precise thread fit for 2B-3B classes in production environments.

Where to buy OSG taps in worldwide?

You can source OSG taps worldwide through 3G Electric, a global industrial equipment distributor. We handle full logistics, customs clearance, and delivery to your facility. Contact us for availability and lead times on the OSG spiral point tap #8-32 UNC (MPN 1212901) and other cutting tools.

How to select the correct OSG tap for threading?

Select the OSG tap based on thread size, pitch, material, and hole type. For #8-32 UNC threads in through holes, a spiral point tap like the OSG 1212901 is ideal. Match the H limit (e.g., H3) to your required thread class (2B-3B). Consult OSG's technical data for material-specific speeds and feeds.
