This 1995 Current EDM ST300 is a Japanese-built manual small-hole EDM drill — a "hole popper" — built around 12" x 8" x 16" of X/Y/Z travel, a 10.5" guide-axis (W) stroke, and a precision-lapped 12" x 12" granite worktable that holds workpieces up to 682 lbs in an 18" x 16" flushing work tank. Running 220V / 3 KVA power with 30 A mean / 57 A peak discharge, a servo-controlled head, XYZ DRO, drill-depth input, and electrode diameters from 0.004" to 0.256" (0.1-6.5 mm), it pops starter holes through hardened tool steel and exotic alloys to depths up to 300x the electrode diameter — drilling a 0.040" hole through 1" tool steel in roughly 35 seconds, virtually burr-free, at any angle. Compared to a conventional drill press or older spark-erosion poppers that rely on manual feel with no positional feedback or automation, the ST300 adds an XYZ digital readout, automated initial zero-set, auto mode, electrode-retract input, and a discharge-on-timer with an independent volt/amp meter for fine servo control — features that turn a single-purpose hole driller into a repeatable, walk-away platform for wire-EDM starter holes, broken-tap removal, and cooling-line work that a bare popper can't match.

With 12" x 8" x 16" travels, a 12" x 12" granite table, XYZ DRO, and electrodes from 0.004" to 0.256", it's the machine that makes the impossible starter hole routine. **All descriptions and specifications are preliminary and must be confirmed by buyer prior to purchase.** Live Tooling / Milling Specifications Vertical Table / Pallet Size: 12" x 12""" X-Travel: 12.00" Y-Travel: 8.00" Z-Travel: 16.00" Max Table/Pallet Load: 1,000lbs Max Workpiece Weight: 682lbs EDM Tank Size: 18" x 16" Spindle Second Spindle Tool Changer Turret Control Control Make/Model: XYZ DRO Tailstock / Steadyrest Options Machine Options: Transformer Product Description: EDM Hole Drill / "Popper" X-Axis Travel: 12" (300 mm) Y-Axis Travel: 8" (200 mm) Z-Axis Travel: 16" (406 mm) Guide (W) Axis Travel: 10.5" (266 mm) Max Workpiece Weight: 682 lbs (310 kg) Granite Worktable Size: 12" x 12" (300 x 300 mm) Work Tank Capacity: 18" x 16" (450 x 400 mm) Electrode Drill Diameters: 0.004" to 0.256" (0.1 to 6.5 mm) Max Electrode Length: 17.7" (450 mm) Drilling Depth Capability: Up to 300x Electrode Diameter Guide Shoe to Table: 2" min / 12.5" max Hold-Down Inserts: 9x M8 Power: 220 Volts / 3 KVA Discharge Current: 30 Amps Mean / 57 Amps Peak Approx.
