EDM Hole Drilling in Cherkasy: Thin and Deep Holes in Hard Steels

In modern metalworking, some tasks cannot be solved properly with conventional mechanical drilling. This is especially true for ultra-thin and deep holes, machining of hardened steels, tool steels, dies, punches, molds, stamping tools, and parts after heat treatment. In such cases, EDM hole drilling is used. This technology makes it possible to produce precise small-diameter holes even in very hard materials.

Bas-Agro LLC offers EDM hole drilling services in Cherkasy for holes with a diameter from 0.5 mm and a depth of up to 300 mm. We also perform broken tool removal by EDM burning: drills, taps, studs, and other hard elements that remain inside a part.

What Is EDM Hole Drilling?

EDM hole drilling is a type of electrical discharge machining. The essence of the technology is that material is removed not by the cutting edge of a tool, but by electrical discharges between the electrode and the workpiece. This makes it possible to process high-hardness materials where a conventional drill quickly wears out, overheats, or breaks.

The main advantage of this method is the ability to make small-diameter holes at considerable depth. For conventional drilling, a hole with a diameter of 0.5-1 mm and a depth of tens or hundreds of millimeters can be a very difficult task. This is especially true if the part is made of hardened steel or has a complex shape. EDM hole drilling helps solve such tasks in a more technological and predictable way.

What Tasks Does Bas-Agro LLC Solve?

At the production facility of Bas-Agro LLC, we perform EDM hole drilling from 0.5 mm in diameter and up to 300 mm in depth. This service is relevant for manufacturing companies, repair workshops, tooling departments, machine-building enterprises, and the agricultural sector.

We can process:

• hard steels;
• hardened steels;
• tool steels;
• parts after heat treatment;
• dies, punches, and stamping tools;
• molds;
• knives, shafts, and housing components;
• custom parts based on a sample, drawing, or technical specification.

This type of machining is especially important where it is necessary to obtain a thin, long, and accurate channel in a material that is difficult to drill by traditional methods. For example, these may include technological holes, cooling channels, starter holes for further EDM wire cutting, holes in tooling equipment, or repair operations during the restoration of complex parts.

EDM Burning of Broken Drills, Taps, and Other Tools

A separate area of work is broken tool removal by EDM burning. In practice, it often happens that a drill, tap, stud, or another hard element breaks inside a part. If you try to remove it mechanically, you may damage the seating surface, thread, or the part itself. In some cases, a part becomes unusable simply because of one broken tool stuck inside a hole.

EDM burning allows the broken tool to be carefully destroyed or removed without rough mechanical impact on the part. This is especially important when repairing expensive parts, housing components, shafts, agricultural machinery units, molds, dies, and other critical tooling.

Instead of scrapping the part, it is often possible to restore its functionality and continue using it. For production, this means saving time, reducing costs, and returning equipment to operation faster.

Why This Matters for Hard and Hardened Steels

Hardened steel has high hardness and wear resistance, but these properties also make it difficult to machine mechanically. A conventional cutting tool experiences increased load when working with such materials. There is a risk of overheating, drill deflection, tool breakage, hole geometry distortion, and surface damage to the part.

EDM technology works differently. It does not depend on classical cutting in the usual sense. Therefore, this method is suitable for machining hard materials when it is necessary to maintain accuracy and make a hole where conventional drilling does not provide a stable result.

This is especially valuable for toolmaking, repair of parts after heat treatment, production of custom components, and restoration of working units where a dimensional error or surface damage can lead to rejection.

See the Process in the Video

An example of the EDM hole drilling process and the finished result can be seen in the Bas-Agro LLC video: https://youtube.com/shorts/G_q7u98CuOo

The video shows a real production process where holes are machined using electrical discharge technology. This format clearly demonstrates how the technology works and what result can be achieved when making thin and deep holes in hard materials.

Where EDM Hole Drilling Is Used

EDM hole drilling is in demand in various areas of metalworking and repair. For the agricultural sector, this technology is useful when restoring and manufacturing parts for agricultural machinery, where strong steels, wear-resistant elements, shafts, bushings, housings, knives, pins, tooling, and custom units are often used.

The technology is also used in machine building, toolmaking, industrial equipment repair, and the production of stamping tools and molds. The more complex the material and the higher the accuracy requirements, the more important it is to choose the right machining method.

Advantages of Working with Bas-Agro LLC

Bas-Agro LLC has its own production equipment and practical experience in metalworking. We work not only with standard tasks, but also with custom parts that require an individual approach and a clear understanding of the material, geometry, and purpose of the component.

Service advantages:
