EDM Drilling Machines (Hole Poppers) Operator & Technician Training

Offered by Pertecnica Engineering

EDM Drilling Machines, commonly referred to as “Hole Poppers,” are specialized Electrical Discharge Machining systems used to create small, precise holes in hard and conductive materials. These machines employ controlled electrical sparks to erode material without mechanical force, making them ideal for intricate and high-hardness components. They are widely used in mold and die manufacturing, aerospace, and precision engineering where conventional drilling methods are not feasible.

In modern industries, EDM drilling ensures high accuracy, consistent hole quality, and the ability to work with difficult-to-machine materials such as hardened steel, titanium, and superalloys. Skilled operators and technicians are essential for tool alignment, process parameter control, and monitoring hole quality. This training program emphasizes hands-on learning to develop industry-ready EDM drilling skills.
