Product Description

OSG General Purpose Spiral-Point Taps.

Frequently Asked Questions

What is the OSG spiral point tap 2849801 used for?

This 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, making it ideal for high-speed production tapping in automotive, aerospace, and general manufacturing applications.

What are the specifications of the OSG 2849801 tap?

The OSG 2849801 is a 1 1/8"-7 UNC spiral point tap with a H6 / 2B-3B tolerance class. It has 4 flutes and a plug chamfer. This general-purpose tap is designed for consistent thread quality in production environments.

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 facility. Contact us for availability and lead time on the OSG 2849801 or other OSG tooling.

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

Select an OSG tap based on thread size, pitch, material, and hole type. For through holes, a spiral point tap like the 2849801 pushes chips ahead. Match the tap tolerance (e.g., H6) to the required thread class (2B-3B). Consult OSG's technical data for material-specific speeds and feeds.
