High-speed EDM drilling machines use rotating tubular electrodes and electrical discharge erosion to produce small, deep holes in any conductive material — a process that conventional twist drills cannot match when it comes to hardened surfaces, extreme depth-to-diameter ratios, or angled entry points.

Baoshijie's EDM drilling range covers two product lines. The DB703 is a compact, cost-efficient machine for general-purpose small-hole drilling, accepting electrode diameters from 0.3–3 mm with depth-to-diameter ratios exceeding 300:1. The CNC3545 and CNC4565 are full CNC models that add servo-driven X/Y axes, AC servo spindle motors, Taiwan-sourced circuit boards, and a 17-inch HD display for greater positioning accuracy, lower fault rates, and more convenient operation in demanding production environments.

Both lines accept ordinary tap water as the dielectric fluid, support direct penetration from inclined or curved surfaces, and are equipped with automatic edge-finding and 100% penetration detection to maximize process reliability.
