No flames are needed, preventing the potential hazards of traditional heating methods and minimizing the impact on surrounding parts. No water cooling required, and operation does not need professional certification.

The bolt heater tool meets most complex metal heating needs. The U-shaped coils easily handle irregular workpieces. The purple copper conductive wire is more efficient than regular copper wire, and the glass fiber insulation layer offers superior resistance to breakage.

The heat dissipation design has been upgraded, with multiple ventilation holes and an internal cooling fan to prevent frequent overheating. The bright LED light helps you work smoothly in the dark and serves as a reminder not to touch the coils. The textured handle is non-slip for comfortable use.

Simply loosen the two side nuts on top to easily replace the coils. The induction bolt heater tool locks securely and is not easy to loosen.
