Product Description

The OSG Spiral Point Tap (5/8"-11 UNC, MPN 1593208) is an oversized spiral-point tap with a 2B+ tolerance, 3-flute design, plug chamfer, and TiCN-coated high-speed steel construction. It is designed for through-hole threading applications requiring a slightly larger thread diameter.

Frequently Asked Questions

What is the OSG spiral point tap 5/8"-11 UNC used for?

This OSG spiral point tap is designed for through-hole threading in metalworking. Its TiCN coating and plug chamfer make it suitable for production tapping in steel and alloys, commonly used in automotive, aerospace, and general machining applications.

What are the specifications of the OSG 1593208 tap?

The OSG 1593208 is a 5/8"-11 UNC spiral point tap with a 2B+ oversized thread class, 3 flutes, plug chamfer, and TiCN coated high speed steel. It is designed for through-hole tapping and provides improved thread fit for plated or coated parts.

Where to buy OSG taps in worldwide?

3G Electric supplies OSG taps like the 1593208 to customers worldwide. We handle full logistics, customs clearance, and delivery to your facility. Contact us for pricing and lead time on this and other OSG cutting tools.

How to select the correct tap for a 5/8"-11 UNC thread?

For a 5/8"-11 UNC through-hole, use a spiral point tap like this OSG model. Choose plug chamfer for general use, and consider TiCN coating for abrasive materials. The 2B+ oversized class compensates for post-plating shrinkage. Always match tap to material and hole type.
