Built for Bladesmiths Who Demand Even Heat
The Evenheat KO 27 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 27" Deep chamber gives you 0.77 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 27 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.
You'll pick your digital controller at checkout. Your options include: TAP Smart touchscreen — virtually unlimited program storage and Wi-Fi capable with the dongle for phone/tablet monitoring; Rampmaster with a numerical keypad, up to 12 firing programs with 8 segments each; Set-Pro — economical digital control. Not sure which one fits your workflow? That's exactly the kind of thing we help with.
