1300W Handheld Mini Magnetic Induction Heater Bolt Removal Tool Flameless Induction Heater For Rusty Screw Removing Nut

Remove rusted, frozen, or corroded bolts and nuts without an open flame. This 1300W handheld induction heater uses electromagnetic fields to heat conductive metals rapidly – reaching 300°C on a 20mm bolt in approximately 30 seconds (max 750°C). Includes three coil sizes (30mm, 40mm, 50mm) for various fastener diameters. Ideal for automotive repair, machinery maintenance, and heat-treating small metal parts. Built-in cooling fan and overheat protection ensure safe, long-lasting operation.

This tool generates a high-frequency electromagnetic field through the induction coil. When positioned around a conductive metal bolt or nut, eddy currents are induced within the metal, causing it to heat from the inside out. The result:

• Fast heating – up to 750°C maximum
• Precise – heat concentrates on the metal fastener, not surrounding components
• Flameless – no fire risk, no gas needed
• Clean – no soot or combustion residues

Safety Features

• Activates during operation to cool internal components
• Allows extended use without overheating
• Shuts down or limits power if internal temperature exceeds safe limits
• Protects the tool from damage
• Extends service life
• No fire risk near fuel lines, brake hoses, or wiring
• Safe for use in engine bays
• No hot gas cylinders to store

Multiple Coil Sizes for Various Fasteners

The kit includes six induction coils in three sizes (two of each):

• Ø30mm (2 pcs): Smaller bolts, nuts, fasteners
• Ø40mm (2 pcs): Medium suspension nuts, general automotive
• Ø50mm (2 pcs): Larger pulleys, bearings, gears
• Spare wire (2 pcs): Custom coil shaping for unique access

How to Use:

• Select appropriate coil – choose the size that fits around the stuck bolt/nut (not too tight, not too loose).
• Attach coil to the induction heater unit.
• Power on the unit and position the coil around the fastener.
• Apply heat – watch or time the heating process (approx. 30 seconds for 20mm bolt to reach 300°C).
• Attempt removal – using a wrench or socket while the fastener is hot (use heat-resistant gloves).
• Allow to cool – the fastener will cool quickly once the coil is removed.
• Clean up – rusted residue may flake away.

Tips for Best Results:

1. Clean the fastener if possible – dirt and grease reduce efficiency
2. Choose the right coil – coil should fit closely around the fastener for best coupling
3. Heat until red/orange glow for severe rust (indicates ~700-800°C)
4. Use penetrating oil after heating – the heat draws oil into threads
5. Protect nearby components – even though flameless, hot fasteners can melt plastic or wires
6. Use heat-resistant gloves – the fastener will be extremely hot
7. Work quickly – once coil removed, the fastener cools fast
