Frequently Asked Questions

What is the OSG spiral point tap 1/4"-20 UNC used for?

The OSG spiral point tap 1/4"-20 UNC is used for threading blind or through holes in ferrous and non-ferrous materials. Its spiral point design pushes chips ahead, reducing chip clogging in production tapping applications. It is suitable for general-purpose threading in automotive, aerospace, and general manufacturing.

What are the specifications of the OSG spiral point tap MPN 2809400?

The OSG spiral point tap MPN 2809400 has a thread size of 1/4"-20 UNC, a thread limit of H2 / 2B-3B, 3 flutes, and a plug chamfer. It is a general-purpose spiral-point tap designed for through-hole tapping. The H2 tolerance ensures precise fit for 2B-3B class threads.

Where to buy OSG spiral point taps worldwide?

You can source OSG spiral point taps worldwide through 3G Electric, a global industrial equipment distributor. We handle full logistics, customs clearance, and delivery to your location. Contact us for availability and lead time on the OSG spiral point tap MPN 2809400.

How to select the correct OSG spiral point tap for a job?

To select the correct OSG spiral point tap, match the thread size (e.g., 1/4"-20 UNC) and class (e.g., H2 / 2B-3B) to your hole requirements. Use a spiral point tap for through holes to push chips forward. Consider material hardness and tap coating for extended tool life. Consult OSG's technical data for optimal performance.
