Frequently Asked Questions

What is the OSG spiral point tap M8x1.25 used for?

This OSG spiral point tap is used for cutting internal metric threads in through-hole applications. The spiral point design pushes chips forward, making it ideal for production tapping in steel, aluminum, and cast iron across general machining and industrial manufacturing.

What are the specifications of the OSG 1981401 tap?

The OSG 1981401 is a general purpose spiral point tap with M8x1.25 metric thread, D5 / 4H-6H tolerance, 3 flutes, and a plug chamfer. It is designed for through-hole tapping and is suitable for a wide range of materials in industrial machining operations.

Where to buy OSG taps in worldwide?

3G Electric supplies OSG taps like the 1981401 to customers worldwide. We handle full logistics, customs clearance, and delivery to your facility. As a global industrial sourcing partner, we provide genuine OSG cutting tools for your production needs.

How to select the correct tap for a through-hole application?

For through-hole tapping, choose a spiral point tap like this OSG M8x1.25. The spiral point pushes chips ahead of the tap, preventing chip clogging. Ensure the tap size matches the thread specification (M8x1.25) and that the tolerance class (D5 / 4H-6H) suits your required fit.
