Description
Bernardo Drill and Milling Machine KF 20 – 230 V
The Bernardo KF 20 is a compact drill and milling machine combination, designed for demanding hobbyists, model makers, and small workshops. With a drilling capacity of up to 13 mm in steel and face milling up to 30 mm, it combines versatility and precision in one machine.
Spindle speed is continuously adjustable across two ranges (0–1000 / 0–2500 rpm), allowing optimal adaptation to the material and type of processing. The MK 3 taper, the robust 385 × 90 mm table, and the 235 × 100 mm travels enable accurate machining even on complex workpieces. The swiveling head from –45° to +45° further increases operational flexibility.
With a 0.35 kW (S1) motor and an output power of up to 0.55 kW (S6), the KF 20 ensures reliable performance while maintaining compact dimensions and a low weight of approximately 50 kg, suitable for workshops and garages with limited space.

Frequently Asked Questions
What is the difference between a drill press and a drilling-milling machine?
A drill press only has vertical spindle movement and a rotating table — suitable exclusively for drilling. The drilling-milling machine (KF series) adds dovetail guides on the X and Y axes that allow the workpiece to be moved in two directions during machining: this enables face milling, slab milling, boring, and multiple drillings without repositioning the workpiece. The cast iron rigidity of the KF series is crucial for absorbing the lateral forces of milling, which a standard drill press cannot withstand.
What cutters are used with the MT3 / MT4 taper?
The Morse taper MT3 or MT4 of the KF series accepts: tapered shank cutters (with direct reduction in the spindle), tapered shank tool holders, ER32/ER40 collets for cylindrical shank cutters. With the MT3→B16 reduction, the keyless drill chuck for standard drill bits is mounted. For face milling, face milling cutters with the corresponding tapered shank are used. Always check the maximum permissible peripheral speed for each tool before use.
Does the Vario-drive system work without stopping the machine?
Yes. The Vario-drive system continuously adjusts the speed via a mechanical variator without stopping the machine or moving belts — you turn the knob during operation. To switch from slow drilling on hard steel to fast milling on aluminum takes only 3 seconds instead of 2–3 minutes of machine downtime with the traditional belt change.
Are spare parts and assistance available?
Original Bernardo spare parts available with 3–5 working days shipping. Customer support in Italian available.
How much space is needed in the workshop?
KF series milling machines have a smaller footprint compared to BFM/WFM workshop milling machines. Consider free space equal to the longitudinal travel on both sides of the table, plus 60 cm for safe operation. Contact Krollit for the full dimensions of the specific model.
