Bimetal - high quality
Bimetal all-metal heatbreak for dual V6-style hotends, with an M6 × 1 thread for the heater block and a smooth Ø6.95mm upper body for retention in a heatsink designed for nominal Ø7mm heatbreaks.
Its construction combines titanium in the thermal bridge with copper in the cold section. Titanium limits heat propagation from the block, while copper helps transfer heat reaching the upper section into the heatsink.
Advantages of the bimetal construction
- Helps thermally separate the hot block from the heatsink.
- Supports heat transfer into the cold-side heatsink.
- Keeps PTFE outside the hot heater-block area.
- Can reduce heat creep when the heatsink receives sufficient, even airflow.
| Feature | Nominal specification |
|---|---|
| Overall length | 20.5mm |
| Heater-block thread | M6 × 1; 5.5mm section |
| Heatsink body | Smooth Ø6.95 × 13.5mm |
| Filament bore | Ø1.9 to 2.0mm |
| Cold-side PTFE guide inlet | Ø4.2mm; 4mm deep |
| Filament | 1.75mm |
Compatible components
The M6 side can be paired with the standard V6 heater block for a thermistor, the V6 block for 3mm cartridge sensors or the Brass V6 block for 3mm sensors, provided the complete assembly retains the corresponding V6 sealing geometry.
The nominal Ø7mm smooth body is designed for heatsinks that secure the heatbreak through a matching bore and retention system, such as the Chimera-style aluminium dual heatsink for two V6 hotends. On a dual toolhead, also check retention of both heatbreaks, cooling and nozzle height alignment.
It is not directly interchangeable with an M7 heatbreak. If your heatsink has a female M7 thread, choose the V6-style M6/M7 bimetal heatbreak.
Installation
- Insert the smooth copper body into the heatsink's Ø7mm bore and secure it using the toolhead's retention system.
- Thread the titanium M6 end into the heater block.
- Tighten the nozzle against the heatbreak inside the block to seal the filament path.
- Avoid twisting the thermal bridge and perform the final hot tightening while correctly holding the block.
- Check cooling and, on dual systems, level both nozzle tips before printing.
After installation, retraction may need review, PID control may need retuning if thermal response changes, and nozzle height or Z offset should be checked again. The heatbreak itself requires no dedicated firmware parameter.
Package contents: 1 M6/Ø7mm bimetal heatbreak. Heater block, heatsink, nozzle and PTFE tube are not included.
