• 3/4"; I.D. preformed coil heats nuts up to 5/8"; in deep areas up to 11";
• Heat and expand frozen, rusted, or thread-lock compound nuts with out the collateral damage from a flame
• Uses high frequency magnetic fields to heat metal and only metal, induction heat
• Operates on 120 volts/1000 watts of power!
• Faster and safer than a torch
• Estimated 500 uses minimum. Heating a nut red hot will reduce the life of this coil.
