Bimetal - high quality
Trianglelab all-metal bimetal heatbreak for V6-style hotends, with an M6 thread for the heater block and an M7 thread for the heatsink. Its nominal length is 22mm and it is designed for 1.75mm filament.
Its three-piece construction combines a polished stainless-steel centre tube with copper-alloy sections. The narrow steel bridge limits heat travelling upwards from the block, while copper supports heat transfer in the hot section and heat removal into the cold-side heatsink.
What a bimetal heatbreak provides
- Sharper thermal transition: helps reduce premature filament softening when cooling is correct.
- All-metal path: PTFE does not extend into the hot heater-block area.
- Polished Ø1.9mm bore: closely guides nominal 1.75mm filament.
- Trianglelab construction: three joined parts create a very narrow thermal break.
Trianglelab rates the heatbreak itself up to 450°C. This does not automatically raise the safe limit of the complete hotend, which is determined by the sensor, heater, block, nozzle, wiring, cooling and firmware.

Compatible heater blocks and heatsinks
The M6 end can fit V6 blocks with the same thread, effective length and sealing geometry, such as the standard V6 thermistor block, the V6 block for 3mm cartridge sensors or the Brass V6 block for 3mm sensors.
The M7 thread suits parts such as the M7 V6 Bowden heatsink, the compact M7 V6 heatsink or the Trianglelab V6DM M7 heatsink.
Conditional compatibility: matching M6/M7 threads alone do not guarantee correct assembly. Also check length, nozzle contact, sensor, heater and available toolhead space. This is not a direct replacement for Revo, Dragon, Rapido, CHC or proprietary hotends.
Installation and setup
- Install the copper M7 end in the heatsink and the M6 end in the heater block.
- Thread the nozzle so that it seals against the heatbreak inside the block. A small gap should remain between the nozzle hex and the outside face of the block.
- Always hold the block during tightening and do not transmit torque through the thin centre tube.
- Perform the final hot-tightening procedure appropriate for the nozzle and complete hotend.
- Keep the heatsink fan running whenever the hotend is hot, then check retraction, Z offset and PID control if thermal response changes.
If thermal compound is used, apply it only at the cold interface between the heatbreak and heatsink, never inside the filament path or on the nozzle-to-heatbreak sealing faces.
Choose it if…
- You want to convert an M6/M7 V6 hotend to an all-metal filament path.
- You want a sharper thermal transition without replacing the complete hotend.
- Your block, heatsink and nozzle retain the corresponding V6 geometry.
Do not choose it if…
- Your heatsink uses a smooth Ø7mm bore; use the Trianglelab M6/Ø7mm dual-hotend version instead.
- You need a flow upgrade by itself: a bimetal heatbreak does not make a hotend high-flow.
- You cannot ensure continuous cold-side cooling and a correct nozzle seal.
Package contents: 1 Trianglelab M6/M7 bimetal heatbreak. Heater block, heatsink, nozzle and PTFE tube are not included.
