CNC EDM Drill Machine Manufacturer in India
Berlin Machine manufactures CNC EDM drill machines designed for accurate small hole drilling in hardened and conductive materials. Our machines are commonly used in tool rooms, mold shops, aerospace components, and precision engineering applications where conventional drilling cannot deliver reliable results.
The machine supports drilling from Ø 0.2 mm to Ø 3.0 mm with stable spark control and consistent depth accuracy. Since there is no mechanical cutting force, parts remain stress-free even when working on hardened steel or carbide.
With over two decades of manufacturing experience and installations across India, our focus remains simple — build machines that run consistently on the shop floor and deliver repeatable production performance.

What is a CNC EDM Drill Machine?
A CNC EDM drill machine is a precision machine used to drill very small and deep holes in electrically conductive materials. It is commonly referred to as a small hole EDM drilling machine and is widely used in tool rooms and mold manufacturing.
Unlike conventional drilling, the machine does not use cutting force. Instead, a rotating tubular electrode generates controlled electrical sparks that gradually erode the material and create the hole. Because there is no physical cutting pressure, even hardened steel and carbide can be drilled without tool breakage or part distortion.
This makes CNC EDM drilling ideal for:
Micro holes in hardened and heat-treated materials
Deep and narrow holes with consistent accuracy
Clean, burr-free drilling
Starter holes required before wire cut EDM operations
When conventional drills struggle due to hardness or precision requirements, CNC EDM drilling becomes the reliable solution.
Benefits of CNC EDM Drill Machine
- Accurately drills micro holes starting from Ø 0.2 mm
- Performs reliably on hardened steel, carbide, and heat-treated materials
- No cutting force, so delicate parts remain stress-free
- Ideal for deep and narrow holes where conventional drills fail
- Produces clean holes without burrs or distortion
- Creates precise starter holes for wire cut EDM operations
- Optimized spark control reduces electrode wear
- CNC automation ensures consistent and repeatable production results
Frequently Asked Questions (FAQs)
Our CNC EDM drill machine can drill holes starting from Ø 0.2 mm. This makes it suitable for micro-hole applications such as mold venting and precision starter holes.
Yes. EDM drilling works effectively on hardened steel, carbide, and other heat-treated conductive materials because it removes material using electrical discharge instead of mechanical cutting force.
The standard electrode diameter range is Ø 0.2 mm to Ø 3.0 mm, allowing both micro-hole drilling and slightly larger precision holes depending on the application.
EDM drilling can create deep, narrow holes with high aspect ratios. The achievable depth depends on material type, hole diameter, and machining conditions.
Yes. It is widely used to create accurate starter holes before wire cut EDM operations, ensuring precise positioning and smooth wire entry.
Yes. Berlin Machine provides installation, operator training, and technical after-sales support across India to ensure smooth machine operation.
