Who uses the KF 25 D Vario and for what
Small mechanical workshops, maintenance personnel, and prototyping laboratories use this drill-milling machine for intermediate processing: drilling up to Ø20 mm in steel, face milling up to Ø63 mm, creating keyways on the table, and angular drilling thanks to the inclinable head ±90°. The Vario speed of 50–1,125 / 100–2,250 rpm allows it to adapt to different materials, from mild steels to light alloys.
Its place in the Bernardo range
The Bernardo KF 25 D Vario is positioned in the mid-range of Bernardo drill-milling machines. Above this machine, the range offers the BF 28 BDC and BF 30 G models with greater drilling capacity (20 mm vs. 28-30 mm) and the large BF 45 HSV / FM 45 HSV / FM 50 HSV with 308-362 kg structures for industrial use. Below the KF 25 D Vario, the range offers the KF 10 benchtop series for model making and laboratory use.
Krollit Logistics and Support
Bernardo shipping in 5-9 business days (7 days to the South). For original Bernardo spare parts, shipping in 3-5 business days from Krollit warehouse. Italian-speaking customer support available for technical documentation, product sheets, and spare parts order management. Krollit has been an official Bernardo distributor since 2007.

Frequently Asked Questions
What drilling and milling capacities does the KF 25 D Vario have?
Steel drilling up to Ø20 mm, face milling up to Ø63 mm, end milling up to Ø20 mm.
The stated capacities refer to standard unhardened steels (e.g., C40, S235). For harder materials or alloyed steels, the actual capacity may be lower: in this case, it is advisable to reduce the rotational speed and feed rate to avoid stressing the spindle and tools.
How is the spindle speed adjusted on the KF 25 D Vario?
The machine features continuously adjustable Vario speed in the range of 50–1,125 / 100–2,250 rpm.
Vario adjustment allows fine-tuning the speed to the material and tool diameter without having to change belts or gears. For face milling mild steels, you typically work in the lower range, while for small diameter holes in aluminum, the higher range is used.
What power supply and motor does the KF 25 D Vario have?
0.60 kW (S1 continuous) / 0.90 kW (S6 intermittent) motor with 230 V power supply.
The motor operates with a standard 230 V single-phase power supply, found in all workshop and laboratory environments. The S6 40% rating indicates that the motor can deliver maximum power for intermittent cycles, while the S1 100% rating indicates the nominal power for continuous use.
What are the table dimensions, travel, and spindle taper of the KF 25 D Vario?
Cross table 500 x 180 mm with X/Y travel of 305 / 125 mm, MT 2 spindle taper, spindle travel 52 mm.
The MT 2 spindle taper is an international standard: accessories (self-tightening chucks, tool holders, reduction arbors) are commonly available. The table travels allow working on pieces within the effective useful dimensions (X/Y travels net of clamping encumbrances).
How much does the KF 25 D Vario weigh and what type of installation does it require?
The machine weighs approximately 110 kg and is designed for installation on a rigid base (optional) or a robust workbench, with a 230 V electrical connection.
For transporting and positioning a 110 kg machine, the use of a pallet jack or light crane is recommended. The support bench must be sized for the weight of the machine plus the workpiece, ensuring flatness to avoid compromising precision.
