Product Description

OSG General Purpose Spiral-Point Taps.

Frequently Asked Questions

What is the OSG spiral point tap 1/4"-28 UNF used for?

This OSG spiral point tap is designed for through-hole threading in ferrous and non-ferrous materials. Its spiral point pushes chips ahead, reducing clogging. Common applications include automotive, aerospace, and general manufacturing where UNF threads are required.

What are the specifications of the OSG 2809608 tap?

The OSG 2809608 is a 1/4"-28 UNF spiral point tap with a H2 / 2B-3B tolerance, 3 flutes, and a plug chamfer. It is a general-purpose tap suitable for through-hole threading. The H2 limit ensures precise thread fit for 2B-3B classes.

Where to buy OSG taps in worldwide?

You can source OSG taps, including the 2809608, through 3G Electric. We handle global logistics, customs clearance, and delivery to worldwide destinations. Contact us for availability and lead times; we supply genuine OSG cutting tools for industrial applications.

How to select the correct OSG tap for UNF threads?

Select a tap matching the thread size and pitch, such as 1/4"-28 UNF. Choose the chamfer type: plug for general through-holes. The H2 tolerance suits 2B-3B thread classes. OSG taps are precision-ground; ensure proper cutting speed and lubrication for best results.
