H32Z Manual Small Hole EDM Machine
Guidance from Steve Brown, EDM Specialist, Iron Machine Tool
About the H32Z Manual
The Mitsubishi H32Z is a manual small hole EDM machine engineered for shops that need reliable small hole EDM drilling without the cost of a fully automated system. Also known in the trade as a hole popper, the H32Z burns clean, precise holes through hardened steel, carbide, and other conductive materials regardless of surface hardness. It's a proven choice for mold makers, tool rooms, and prototype shops across Minnesota that need dependable small hole EDM drilling on a manual platform, where automation isn't justified by volume.
How the H32Z Performs Small Hole EDM Drilling
The H32Z uses a rotating tubular brass electrode and controlled electrical discharge to erode material and drill holes through hardened metals without mechanical stress or tool wear concerns. This makes it well suited to small hole EDM drilling and drilling EDM applications where conventional twist drills would break or dull against hardened tool steel. Coolant flushes debris continuously during the process, keeping hole walls clean and dimensionally accurate even on repeat setups.
H32Z Manual Small Hole EDM Machine Specifications
The H32Z is built as a manual, entry-level small hole EDM machine, with a worktable and travel range sized for typical mold and tooling components. Its electrode stroke and diameter range are engineered for both standard small hole EDM drilling and finer micro hole EDM work, giving shops precise control without CNC-level complexity. The specifications below outline the machine's working envelope and electrode capacity.
| Specification | Value |
| Worktable Size (W x D) | 23.6" x 11.8" |
| Travels (X, Y) | 13.8" x 9.8" |
| Electrode Stroke (W-Axis) | 13.4" |
| Electrode Diameter Range | 0.008" ~ 0.124" (optional 0.236") |

Frequently Asked Questions
A: The H32Z is used for manual small hole EDM drilling and micro hole EDM drilling in hardened steel, commonly for mold venting, cooling channels, and wire EDM starter holes.
A: The H32Z supports electrode diameters from 0.008" to 0.124", with an optional 0.236" range, covering both micro hole and standard small hole EDM drilling needs.
A: Small hole EDM drilling uses electrical discharge to erode material rather than mechanical cutting, allowing it to drill through hardened steel and carbide that would break or dull a conventional twist drill.
A: No. The H32Z is a manual machine best suited to low volume or prototype small hole EDM drilling. For repeat production runs, the CNC SD-530 or SD-750 are better suited.
A: Yes. With electrode diameters as small as 0.008", the H32Z handles micro hole EDM drilling in addition to standard small hole work.
