Product Description

The OSG Spiral Point Tap (1/2"-13 UNC, MPN 1232405) is a general-purpose spiral-point tap with a plug chamfer, TiN-coated high-speed steel construction, and 3 flutes. It is specified as H3 / 2B-3B class, designed for through-hole threading in a range of materials.

Frequently Asked Questions

What is the OSG spiral point tap used for?

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

What are the specifications of the OSG spiral point tap 1232405?

The OSG spiral point tap 1232405 has a 1/2"-13 UNC thread, H3 / 2B-3B tolerance, 3 flutes, plug chamfer, and TiN coated high-speed steel. It is designed for general purpose tapping in materials up to 850 °C hardness. The H3 fit ensures precise thread sizing for 2B-3B classes.

Where to buy OSG taps in worldwide?

You can source OSG 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. We supply genuine OSG tooling for manufacturing and maintenance needs.

How to select the right OSG tap for UNC threads?

To select the right OSG tap for UNC threads, match the tap size (e.g., 1/2"-13) to your hole diameter and thread class (2B or 3B). Choose a spiral point design for through holes or blind holes with chip evacuation. TiN coating extends tool life in abrasive materials. Consult OSG's technical data for material-specific speeds.
