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 and ensuring clean threads in production environments across industries like automotive and aerospace.

What are the specifications of the OSG 2842700 tap?

The OSG 2842700 is a 1/2"-20 UNF spiral point tap with a plug chamfer, 3 flutes, and a thread tolerance of H7 / 2B-3B. It is designed for general-purpose through-hole threading in steel and non-ferrous materials.

Where to buy OSG taps in worldwide?

3G Electric supplies OSG taps like the 2842700 to worldwide locations. We handle full logistics and customs clearance, sourcing genuine OSG cutting tools for industrial maintenance and production needs globally.

How to select the right OSG tap for a job?

Select an OSG tap based on thread size, pitch, hole type (through or blind), and material. For through holes, a spiral point tap like the 2842700 is ideal. Match the thread tolerance (e.g., H7 / 2B-3B) to your application requirements.
