Product description: 1.This machine is designed to conveniently remove broken taps, bolts, drills, etc, The size range is M2 to M48 (M2 - M30 for EDM8C model); 2.This machine works by Spark Erosion principle, electrode size is half of the broken tap size, no contact with the work piece, then no damage to work piece. 3.This machine has a submersible pump that provide the dielectric (Tap water) to the work area, it could remove the disintegrated particles from the work piece to improve the burn time; 4.There is a vibration function that quite improve the processing time; 5.With its small size and light weight, it has special superiority for processing on large size work piece. Separated work head could rotate in any direction, very helpful for complex machining. 6.Automation: Auto feed; Depth setting (stop at a specific depth); Alarm and auto retract.
