EdmDrillTM ST400

ST400

Precision EDM Drilling Machine

The EdmDrill™ ST400 is the highest quality manual EDM driller available. It is the ideal choice for those who don’t require CNC capability but demand the superior drilling performance Current EDM is known for. Proudly built in the USA, the ST400 features the Siemens TP700 touch-screen controller, generous table travel and moving bridge design for added stability and weight capacity. The compact design reduces floor space requirements and the fixed worktable offers ergonomic access for operators. The ST400 drills with the widest range of electrode diameters including solid tungsten electrodes as small as 0.003 inch in diameter. The included M-function interface automates drilling with a rotary table, robot or part loader. A unique feature of the ST400 is that it can be upgraded from manual to CNC on your shop floor when the need arises.
