Built for Bladesmiths Who Demand Even Heat
The
Evenheat KO 22.5 is a serious heat treat oven built for makers who push their work. Running on
240V, it gets to temperature fast and holds it dead steady through long soaks.
The 9" W x 5.5" H x 22.5" Deep chamber gives you 0.65 cubic feet of working space. That's enough room to handle a meaningful production batch — knives, small tool work, jewelry heat treat, and similar tasks all fit comfortably.
The 22.5 fires up to 2400°F, which covers the vast majority of steels used in knife making and small parts heat treat. It runs on 240V at 15 amps with a NEMA 6-20 plug.
Included with every order
Stand with tool rest, full operator manual, a 2 year limited warranty through Evenheat, free freight shipping to the US Lower 48.
