Osg 2701200 Round Threading Die 1/4-28 Unf Hss

Product Description

The OSG 2701200 is a round adjustable threading die designed to cut external threads on iron and steel workpieces. It produces 1/4-28 UNF right-hand threads and is manufactured from high-speed steel for durability across production and maintenance threading applications. The die measures 0.8125 inches in outside diameter and 0.25 inches in thickness, fitting standard round die stocks of that size. The adjustable design allows the operator to fine-tune thread fit by expanding or compressing the die within the stock. Machinists, maintenance mechanics, and tool and die tradespeople use this die for restoring damaged threads or cutting new external threads on fasteners and rod stock.

This die is suited for use on iron and steel in both shop and field repair settings. Typical applications include threading bolts, studs, and rod ends to 1/4-28 UNF specification. The adjustable feature makes it practical for production runs where thread tolerance needs to be dialed in incrementally. It belongs to OSG Series 134 and is sized for a standard 0.8125-inch round die stock holder.

Installation Notes

Secure the die firmly in a properly sized round die stock before use. Apply cutting oil generously to the workpiece and die to reduce heat and extend tool life. Advance the die in short increments, backing off periodically to clear chips. Machinists and maintenance trades should inspect the die for cracks or chipping before each use and replace if damaged.
