Evenheat · Heat Treat Oven · Cube Series Evenheat Heat Treat Oven - Cube 7 Model EH-CUBE-7 · 120V · 7″ W × 7″ D × 7″ H · 2350°F max The Cube 7 is Evenheat's smallest heat treating oven — a full firebrick chamber built for bladesmiths, gunsmiths, and machine shops that need precise, repeatable heat treating on a bench, not a 240V shop circuit. It plugs into standard 120V household power and reaches 2350°F, making it a serious hardening and tip-treating tool for makers without a dedicated high-amp line.
Max Temp2350°F (1287°C)
Chamber7″ W × 7″ D × 7″ H
Voltage120V, 12A

Key features
Full Firebrick ConstructionChamber built entirely of heat-treat-rated firebrick for even temperature distribution and fast recovery between cycles.
Side-Opening Cool-Touch DoorDoor swings out and to the side on a spring-loaded phenolic handle that stays cool, keeping the superheated door out of your way during quenching.
Quiet Drive Solid State RelayStandard on every Cube 7. Zero moving parts and up to 60 firings per second for tight, repeatable temperature control.
Swing-View Control EnclosurePivoting control housing lets you angle the display toward you while programming, then lay flat for at-a-glance monitoring.
Relay Access PortService the solid state relay without pulling panels, so downtime for maintenance stays minutes, not hours.
Door ShieldProtects firebrick and reduces handle and door-face temperature through repeated open/close cycles during quench work.
Optional accessories
MK1 Blade FixturePurpose-built rack that holds up to 4 blades at once inside the 7″ chamber, so you can batch tip and edge treatments instead of loading one piece at a time.
Power Interrupt Safety SwitchCuts power to the elements automatically when the door opens and restores it on close — a low-cost safeguard against accidental element damage.
Spare Type K ThermocoupleKeep a backup on hand so a worn probe never turns into a lost production day mid-batch.
High-Temperature GlovesRated for heat treating temperatures and sized for the tight quarters around the Cube 7's compact door.
Controller upgrades
TAP Touchscreen — SDS IndustriesTop Tier
For shops running multiple steels with different soak and ramp requirements, TAP gives the Cube 7 unlimited custom programs and remote monitoring from your phone — useful when you're stepping away between quench cycles.
  • Unlimited programs and firing steps
  • TAP mobile app — monitor from your phone
  • Push notifications when firing completes
  • Adjust temp or add time mid-cycle
  • Auto-updates over Wi-Fi
  • Firing logs and maintenance schedules
Genesis Spark — Bartlett InstrumentsGreat Value
The Genesis Spark delivers reliable digital ramp/hold control with a color touchscreen at a lower price point than TAP — plenty of capacity for most single- and multi-steel heat treating programs.
  • 30 programs × 32 segments each
  • 3.2″ color touchscreen display
  • Wi-Fi for remote updates and diagnostics
  • Ramp/hold and preset modes
  • Preheat capability built in
  • Adjust firing in real time
Common questions
Can the Cube 7 really run on a household outlet?Yes. It's built specifically for 120V power — 12 amps on a standard NEMA 5-15 plug — so a dedicated 15 or 20-amp circuit is all you need. No electrician-installed 240V line required, which is the whole point of this model.
What can I actually fit and heat treat in a 7×7×7 chamber?The Cube 7 is sized for tips, small fixed blades, punches, chisels, and other short tooling rather than full-length knife blades. With the optional MK1 fixture you can load up to 4 blades at once for batch tip-hardening work.
Does it come with the Quiet Drive Solid State Relay, or is that extra?It's standard equipment on every Cube 7, not an upgrade. You get the tighter temperature control and silent operation of solid state switching without paying more for it.
Is this oven only for knife work?No — with a 2350°F ceiling it also handles small-scale glass, PMC/metal clay, and general high-temperature testing, making it a flexible bench oven for a mixed-media shop.
Does buying from Peach State Pottery affect my warranty?No. We are an authorized Evenheat dealer, so your two-year warranty is fully valid and you have direct access to Evenheat's support team. Buying from an unauthorized seller can void your warranty entirely.
