The bolt heater uses a separated motor design, allowing for a larger motor. This enables faster heat transfer in a short time, reducing the risk of uneven heating, which could cause damage to mating surfaces. It can handle thicker, larger workpieces.

The bolt heater tool comes with multiple coils that easily handle irregular workpieces. Whether it's small screws or larger bearings, it provides precise heating. The purple copper conductive wire is more efficient, and the glass fiber insulation layer offers superior resistance to breakage.

The main unit can be carried on your back to reduce concerns about insufficient cable length. The hand-held design ensures a stable grip and more flexible operating angles. The built-in cooling fan helps prevent overheating and guards heat-sensitive parts.

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.
