Pepe® Stepped Ring Stretcher with Ductile Frame

Designed from the ground up, this ring stretcher by Pepe® sets the bar on quality, consistency, and reliability. We engineered this product starting with the heart of the machine, the spline. The spline is machined from solid tool steel billet. Concentricity is key when creating an even, smooth stretch of a solid band. Each of the 6 splines starts on a CNC lathe, machined and then reamed on the inside diameter to create a perfectly concentric cone. This proprietary process took years of work, tooling, and knowledge to create something unique. 

Not stopping at the spline, the reduction die is machined from solid billet (most on the market are cast). The 16 countersunk dies are machined 8 to a side on a 4.5" disc that is nearly 1" thick. Each countersunk hole is machined with specialized tooling resulting in a perfect 17 degree angle. 

The spline, reduction die, and all steel parts are polished and plated in a durable hard finish for a lifetime of use. 

In addition to the revolutionary design process, we have taken it a step further. We are proud to be the first manufacturer to introduce an optional Delrin reducing die as well as pushing rod. This is a huge advantage when reducing bands of softer materials. A durable Delrin reducing die and push rod will help protect against marring. Whether it is a coin-ring, solid gold or platinum band, or any other non ferrous material - this Ring Stretcher by Pepe® will be a workhorse in your workshop. Instructions.
