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 through-hole threading in steel and stainless steel. Its spiral point pushes chips ahead, preventing clogging and ensuring clean threads. It is commonly used in automotive, aerospace, and general machining applications where high-speed production and thread accuracy are critical.

What are the specifications of the OSG 1/2"-20 UNF spiral point tap?

This OSG tap has a 1/2"-20 UNF thread, H5 tolerance for 2B-3B class fit, 3 flutes, and a plug chamfer. It is designed for through-hole threading in steel and stainless steel. The manufacturer part number is 1701701, and it is available as SKU 1701701.

Where to buy OSG taps in worldwide?

3G Electric supplies OSG taps worldwide, handling full logistics and customs clearance. As a global industrial solutions provider, we source genuine OSG cutting tools like the 1/2"-20 UNF spiral point tap and deliver them to your facility. Contact us for pricing and lead time on your order.

How to select the right OSG tap for steel threading?

For through-hole threading in steel, choose a spiral point tap like this OSG 1/2"-20 UNF model. Ensure the tap size matches your hole diameter and thread class (2B-3B). Use proper cutting fluid and speed per OSG recommendations. For blind holes, consider a spiral flute tap instead.
