7/8"-12 HSS Round Adjustable Die

The Drill America DWTSR2-7812 is a high-speed steel round adjustable die for cutting 7/8"-12 threads. It suits maintenance technicians and machinists who need to produce or repair external threads on rods, bolts or pipe. The die is chamfered on both faces for versatile starting conditions.

Installation and common issues

The die fits standard 2 inch outer-diameter holders and adjusts via a fine-pitch screw that opens or closes the thread form. One face offers a 2 to 3 thread chamfer for general threading; the opposite face has a 1 to 1-1/2 thread chamfer for work close to a shoulder. Over-adjustment can oversize threads, while insufficient lubrication accelerates wear.

Pre-order checks

Verify that the workpiece material is compatible with high-speed steel cutting tools. Confirm the holder accepts a 2 inch round die and that the machine or hand stock can apply the required torque. The product carries a California Proposition 65 warning for chemicals known to cause cancer and reproductive harm, so review local safety regulations before use.

Questions about this item

How can I verify the die is cutting a proper 7/8"-12 thread after setup?

Thread a matching 7/8"-12 nut onto the freshly cut rod; it should engage smoothly without binding or excessive play.

What comes in the package and what must I supply separately?

The box contains the HSS round adjustable die only; you will need a compatible die stock or machine holder and cutting fluid.

Which version of the DWTSR2-7812 should I choose for a 7/8"-12 thread?

This single model is made specifically for 7/8"-12 threads with a 2-inch outside diameter; no other capacity versions exist.
