Induction Innovations MD99-611 3/4" Preformed Coil for Mini-Ductor

The Induction Innovations MD99-611 is a 3/4" inner diameter preformed coil designed specifically for use with Mini-Ductor induction heating systems. This specialized coil allows you to heat and expand frozen, rusted, or thread-locked nuts up to 5/8" quickly and safely without the collateral damage associated with traditional flame-based methods.

Key Features:

• 3/4" inner diameter design optimized for heating nuts up to 5/8"
• 7-1/2" length provides effective heating zone
• Uses high-frequency magnetic fields to heat metal selectively through induction
• Operates on standard 120V power with 1000 watts of heating power
• Faster and safer than traditional torch methods
• No flame means reduced fire hazard and no damage to surrounding components
• Estimated minimum 500 uses under normal operating conditions

This preformed coil is an essential accessory for automotive, industrial, and maintenance professionals who regularly work with seized or corroded fasteners. The induction heating method expands the nut without heating the bolt, making removal easier while preserving thread integrity. For maximum coil longevity, avoid heating nuts to red-hot temperatures.
