Bernardo Mill-Drill KF 20 L Super / 230 V
The Bernardo KF 20 L Super mill-drill is a compact and precise machine, suitable for workshops, laboratories, and advanced hobbyists. Thanks to its 500 W DC brushless motor, it ensures optimal torque even at low speeds and silent, maintenance-free operation.
The dovetail guides on the X, Y, and Z axes are adjustable via gibs and can be individually locked, ensuring stability and professional-quality results. The ±45° tiltable head allows for angled machining and chamfering, while the surface-treated cross table with T-slots offers versatility in milling and drilling operations. With continuous speed adjustment from 100 to 2500 rpm, the KF 20 L Super model adapts perfectly to every type of workpiece.

Frequently Asked Questions
What is the difference between a pillar drill and a mill-drill?
A pillar drill only has vertical spindle movement and a rotating table — suitable exclusively for drilling. A mill-drill (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 drilling operations without repositioning the workpiece. The gray cast iron rigidity of the KF series is crucial for absorbing the lateral forces of milling, which a standard pillar drill cannot withstand.
Which milling cutters are used with the MT3 / MT4 taper?
The Morse taper MT3 or MT4 of the KF series accepts: tapered shank milling cutters (with direct reduction in the spindle), tapered shank tool holders, ER32/ER40 collets for cylindrical shank milling cutters. With the MT3→B16 reduction, the self-tightening chuck for standard drills can be mounted. For face milling, milling heads with the corresponding tapered connection 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 simply 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 traditional belt change.
Are spare parts and assistance available?
Original Bernardo spare parts available with 3–5 working day shipping. Customer service 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 clear space equal to the longitudinal travel on both sides of the table, plus 60 cm for safe working. Contact Krollit for the complete dimensions of the specific model.
