Digital radial drilling machine
KRD5016EVS Digital Radial Drilling Machine
The 50 mm frame in the digital series, with the spindle reaching 1615 mm from the column and 1250 mm of horizontal spindle movement. Speed and feed are set on the readout and held by servo control.
Features
- Spindle speed and feed run on frequency conversion and servo control, which simplifies the mechanical structure and takes out a share of the faults that come with it.
- Machining parameters are shown on a digital readout and can be pre-set before the cut.
- A glass scale on the Z axis reads drilling depth back to the control.
- The spindle motor switches automatically between high and low gear to hold cutting speed; spindle and feed motors both carry overload protection.
- The upper guideway surface is inlaid with German 1.2842 alloy steel, which extends rail life and keeps headstock clamping repeatable.
- The arm is surface quenched for rigidity and strength.
- Arm and inner and outer column clamp electrically rather than mechanically, which is stable in service and cuts the failure rate.
- A digital integrated electrical panel replaces the loose-component cabinet.

Model FAQs
Questions Engineers Ask About The KRD5016EVS
Why does the KRD5016EVS’s speed range matter more than its top speed?
The KRD5016EVS runs 20-1600 r/min on a 4# / 5# spindle taper. Big holes in tough material live at the bottom of the range where torque works; small holes want the top. A machine that covers both ends handles the whole job list instead of half of it.
What should I look at inside the KRD5016EVS beyond the spec table?
Two build points matter most on this machine: spindle speed and feed run on frequency conversion and servo control, which simplifies the mechanical structure and takes out a share of the faults that come with it; and machining parameters are shown on a digital readout and can be pre-set before the cut. Structure decides how a machine ages — the specification table tells you what it does new, the build tells you what it does in year five.
What does the KRD5016EVS’s Φ40 / Φ50 mm capacity actually mean?
Capacity figures are quoted in steel — Φ40 / Φ50 mm on the KRD5016EVS. Keep a working margin over your biggest regular hole rather than running the spindle at its limit all day: a machine bought at the limit wears its accuracy off first. In cast iron the same spindle works easier; in stainless, harder.
KRD5016EVS or Z30100 / Z30125 — which fits my work?
Both sit in the digital radial drilling machine group, so the decision is capacity and duty, not kind: put your largest part dimensions, material and yearly quantity against each specification table and one of the two will run out of a figure first. Send the drawing and we will name which of the two fits — including the case where the smaller machine does the job.
How is a new KRD5016EVS proven before it ships?
Every KRD5016EVS is laser-measured to ISO 230-2 over its travels, cuts a test piece that is measured rather than admired, and ships with a serial-numbered report carrying the measured values. If any line misses, the machine goes back into the shop until it passes — the report is a record, not a promise.
