Ocean EDM - River Series Fast Hole Drilling Systems


When you need a hole right now, the River Series delivers.If you’ve ever burned through carbide trying to drill a micro-hole in hardened steel, you already know where this story goes. Ocean’s River Series fast-hole EDMs turn that frustration into a quick, predictable process—popping clean, precise holes through anything conductive, from tool steel to Inconel.

River-35 - Built for production and tough materials

Ocean River 35


The River-35 is the workhorse of the line. It’s built for shops that need to punch holes fast, deep, and consistently. Whether you’re drilling start holes for wire EDM, coolant holes in cutting tools, or vents in mold cavities, this machine just gets it done.

You get a larger work envelope, higher current, and the ability to run fine or heavy electrodes without babying the settings. It’s rugged, repeatable, and ready to work alongside your mills and EDMs all day long.What machinists appreciate most:Quick setup and intuitive control—you don’t need to be an EDM specialist.

  • Handles everything from tiny 0.1 mm electrodes up to 6 mm optional sizes.
  • Strong enough to drill through hardened alloys that conventional drills can’t touch.
  • Designed to live on the shop floor, not in a lab.

If your shop needs repeatable EDM capability for mold, die, or aerospace work, the River-35 belongs in the conversation.

River-3 - Compact, capable, and ready to pop holes anywhere

The River-3 is the smaller sibling—built for tool rooms and job shops that need reliable EDM capability in a compact footprint. It’s ideal for quick setups, prototype work, and wire-EDM start holes. Simple controls, low power requirements, and stable spark performance make it a dependable addition to almost any shop.Think of it as the “plug-and-play” hole popper—fast to learn, fast to run, and low-maintenance.

Why EDM hole-popping still matters

There are a lot of ways to make holes, but only one that truly ignores hardness. EDM drilling uses electrical discharge to vaporize material rather than cut it, so your electrodes don't wear like drills and your holes come out straight, burr-free, and accurate - even in tungsten carbide. 

It's not about replacing your drills. It's about giving your shop the ability to do what drills can't.

The Ocean story - vision, name, and roots. 


Ocean Technologies is a female-owned company. From the start, she set out not just to build machines, but to lead a category on integrity and quality. 

She named the company Ocean because water covers ~70% of the planet, symbolizing universality, life, and connectivity. Her ambition: become the world leader in fast-hole EDM, providing machines that rival top OEMs - but priced for real shops. 

And Rivers? Rivers lead to the ocean. We see the River Series as the channels that deliver small-hole power into your tools, feeding the broader vision. 

What this means for your shop

  • When someone says “I can’t drill that — it’s too hard, too small, too deep” — that’s your opening.
  • Use the River-35 as a daily tool for precision straight internal holes.
  • Use the River-3 when you don’t need full throughput but still want the ability to punch holes others can’t.
  • Don’t oversell it. If a helical internal passage is required, we’ll point them to the right EDM milling or multi-axis option.


Ocean + Innnova

Ocean Technologies has been building reliable EDM solutions for decades. Through Innova Machine Tool, you now have North American access to these proven machines, local support, and integration assistance—whether it’s a single EDM or a full cell setup.
