Advantages:

• Lightweight, small, compact table top design.
• High speed and efficient, low operating costs.
• Easy to use, easy removal of broken taps or other tools.
• After sparking out the midpoint of the tap, or in case of big taps, one shoulder of the tap, it is possible to remove taps of standard sizes M2 - M70. If the electrode is modified in a lathe, possible to remove even bigger taps. After you remove the rest of the tap from thread hole, the thread hole will stay undamaged.
• Uses ordinary tap water as a dielectric. The device can be used directly on the machinery without the need for an external clamped work piece. When used directly on the machine, it uses the coolant emulsion of the machine as a dielectric.
• Uses standard brass rods as electrodes. Ordinary copper rods can also be used.
• Easy to work with large work pieces.
• Removes taps easily without damaging the threads.
• Automatic feed into the Z axis to set the desired depth up to 70 mm.
• Electrode holder till 13mm diameter
• Depth adjustment (depth automatically stops at defined point).
• Selectable shutdown time for accidental short circuiting.
• Optional automatic extraction of the electrode from the hole for the set depth.
• Depth adjustment check indicator, short circuiting indicator, overheat indicator.
• Spark check indicator.
• Possible to use for hole drilling in EDM wire cutters.
• Possible to hole drilling into the sintered carbides (tungsten carbides), other heavily machinable steels and any conductive materials.
