Product Description

OSG Spiral-Point Taps for Steel & Stainless Steel.

Frequently Asked Questions

What is an OSG spiral point tap used for?

An OSG spiral point tap is designed for threading blind or through holes in steel and stainless steel. Its spiral point pushes chips forward, preventing clogging and ensuring clean threads. This makes it ideal for high-production tapping in automotive, aerospace, and general manufacturing applications.

What are the specifications of the OSG spiral point tap #4-48 UNF?

This OSG tap is #4-48 UNF with a H2 / 2B-3B thread tolerance, 2 flutes, and a plug chamfer. It is designed for steel and stainless steel. The manufacturer part number is 1726901. These specs ensure precise thread fit and chip evacuation in demanding materials.

Where to buy OSG taps in worldwide?

How to select the right OSG tap for steel?

Select an OSG tap based on material, thread size, and hole type. For steel and stainless steel, a spiral point tap like this #4-48 UNF with H2 tolerance works well for through holes. Match the chamfer (plug, bottoming, or taper) to your hole depth. Always use proper cutting fluid for best results.
