Who uses the KF 25 L Vario and for what
Small-scale mechanical workshops, maintenance technicians, and prototyping laboratories use this drill-milling machine for intermediate machining: drilling up to Ø20 mm in steel, face milling up to Ø63 mm, keyway cutting, and angular drilling thanks to the ±90° tilting head. 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 L 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 L 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. Customer support in Italian available for technical documentation, product sheets, and spare parts order management. Krollit has been an official Bernardo distributor since 2007.

Frequently Asked Questions
What are the drilling and milling capacities of the KF 25 L Vario?
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 alloy steels, the actual capacity may be lower: in this case, it is advisable to reduce the rotation speed and feed rate to avoid stressing the spindle and tools.
How is the spindle speed adjusted on the KF 25 L Vario?
The machine features continuously adjustable Vario speed in the range of 50–1,125 / 100–2,250 rpm.
Vario adjustment allows for fine-tuning the speed to the material and tool diameter, without needing to change belts or gears. For face milling of mild steels, one typically works 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 L Vario use?
0.60 kW (S1 continuous) / 0.90 kW (S6 intermittent) motor with 230 V power supply.
The motor operates on standard single-phase 230 V power, available 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 L Vario?
Cross table 700 x 180 mm with X/Y travel of 490 / 125 mm, MT 2 spindle taper, 52 mm spindle stroke.
The MT 2 spindle taper is an international standard: accessories (self-tightening chucks, milling arbor holders, reduction arbors) are commonly available. The table travels allow for machining workpieces that fall within the effective usable dimensions (X/Y travels net of clamping obstructions).
How much does the KF 25 L Vario weigh and what kind of installation does it require?
The machine weighs approximately 120 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 120 kg machine, the use of a pallet truck 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.
