Cube 7 Small High-Temp Knife Oven for Precision Blade Heat Treating
The Evenheat Cube 7 offers a smart, space-saving design without sacrificing performance. Its 7″ × 7″ × 7″ firing chamber reaches up to 2350 °F (1287 °C), making it ideal for small-scale firing, heat treating, and glasswork. Built for reliability, it comes standard in 120V single-phase, with 240V available upon request.
Engineered for consistent results, the Cube 7 runs flawlessly on both 50 Hz and 60 Hz line frequencies, ensuring global compatibility. Designed for 120V single-phase power and Evenheat’s proven craftsmanship, this kiln is an excellent choice for studios, workshops, and classrooms where space is limited but performance is essential.
Built to last, it features a swing-out door, cool-touch handle, door shield to protect the firebrick, and an easy-access relay port—all designed to keep you safe, minimise maintenance, and let you focus on your craft rather than the hardware.
