Eight-piece induction coil kit

The VEVOR 8PC71LL kit supplies eight flexible induction coils for use with compatible flameless heaters. It targets automotive technicians and maintenance crews who need to free rusted bolts and nuts without open flame. Two coils each of 30 mm, 40 mm and 50 mm diameter cover common fastener sizes, while two 750 mm free-forming coils can be shaped for awkward access. The set suits workshops that regularly tackle seized hardware on vehicles or machinery.

Insulated flexible coils for daily shop use

Each coil is insulated and abrasion-coated to protect the operator and resist premature wear, rated for several hundred heating cycles. The flexible construction lets users bend every coil to match the workpiece, then reshape it for the next job. At 1.54 lbs total weight the kit adds minimal bulk to a tool bag. Damaged insulation requires immediate coil replacement to maintain safety.

Replaces single-size coils and torch methods

This kit replaces the need to stock multiple individual coils or rely on oxy-fuel torches for bolt removal. The jump is worth it when a workshop faces a variety of fastener diameters and wants flameless, localised heat with repeatable coil life. Buyers who only ever work on one bolt size or who lack a compatible induction heater will not use the full range.

Questions about this item

What bolt diameters does the 30 mm coil in this kit heat?

The 30 mm coil heats bolts from 5 mm up to 30 mm in diameter.

How much space is needed to store the 750 mm free-forming coils?

The package measures 2.36 x 11.81 x 7.87 inches, so the 750 mm coils fit inside that box.

How are the coils attached to the induction heater and what step is often missed?

Slide the coil onto the heater output terminal and tighten the locking nut; the step often missed is checking the insulation for damage before each use.
