Uni-Tek 300 Tap Burner - 110V - Servo Feed Head - Broken Bolt Extractor

Uni-Tek (Electro Arc) Model 300 Swivel Head Tap Disintegrator | Servo Feed

The Uni-Tek (Electro Arc) Model 300 is a precision metal disintegration system designed for the rapid removal of broken taps, drills, and studs without thread damage. This specialized Swivel Head model features a 360° rotating arm, allowing the operator to position the head at any compound angle—essential for extracting broken fasteners from engine blocks, large castings, or immovable heavy machinery.

This 1987 unit (S/N 081887R) is equipped with the high-performance Servo Feed Head, which automatically monitors the electrical gap between the electrode and the broken tool. Unlike manual units, the servo system prevents electrode welding and ensures a constant, optimal arc for faster disintegration. Operating on a standard 110V single-phase circuit, this portable machine is the "gold standard" for maintenance departments and machine shops requiring professional-grade extraction capabilities.

Key Features

• Precision Servo Control: Automatically maintains the disintegration arc, providing hands-free operation and maximizing electrode life.
• 360° Compound Angle Arm: The swivel head provides unmatched versatility, allowing the electrode to reach recessed or angled holes that fixed-table machines cannot.
• 110V Portability: High-tonnage disintegration power that can be plugged into standard industrial 110V outlets, eliminating the need for 480V drops.
• Integrated Coolant System: Built-in high-pressure pump flushes out metallic debris during the cut, ensuring a clean cavity and preventing heat buildup.
• Vibration Amplifier: Features adjustable vibration control to optimize cutting speeds across different materials like Carbide and HSS.
