Frequently Asked Questions

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

The OSG spiral point tap M8x1.25 is used for threading blind or through holes in ferrous and non-ferrous materials. Its spiral point design pushes chips ahead, reducing chip clogging. It is ideal for production tapping in automotive, aerospace, and general manufacturing applications.

What are the specifications of the OSG spiral point tap M8x1.25?

The OSG spiral point tap has an M8x1.25 metric thread, D5 / 4H-6H tolerance, 2 flutes, plug chamfer, and is made of high-speed steel. The manufacturer part number is 1981300. It is designed for general-purpose threading in through or blind holes.

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 times on the OSG M8x1.25 tap (MPN 1981300).

How to select the correct OSG tap for a threading application?

To select the correct OSG tap, match the thread size (e.g., M8x1.25), tolerance class (D5 / 4H-6H), and chamfer type (plug) to your hole and material. For through holes, spiral point taps push chips forward. For blind holes, consider spiral flute taps. Consult OSG's technical data for material-specific recommendations.
