Description
Bernardo Mill-Drill KF 25 L Vario – Mill-Drill with tilting head
The Bernardo KF 25 L Vario mill-drill is a compact and robust machine, suitable for drilling, milling, and threading. Thanks to its 2-stage gearbox and continuous speed adjustment (50–2250 rpm), it can easily adapt to any material and type of processing.
The 700 x 180 mm cross table, with travels of 490 x 150 mm and a graduated scale, ensures ample operating space and precision. The ±90° tilting head allows for angular milling and chamfering, while the tapered bearings guarantee high spindle concentricity (≤0.015 mm).
Equipped with right/left rotation for threading, a digital display for speed and spindle travel, adjustable protection, and an CE-compliant EMC filter, it is a complete and reliable machine, suitable for laboratories and workshops.

Frequently asked questions
What is the difference between a drill press and a mill-drill?
A drill press only has vertical spindle movement and a rotating table — suitable exclusively for drilling. The mill-drill (KF series) adds dovetail guides on the X and Y axes, which 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 fundamental for absorbing the lateral forces of milling, which a standard drill press cannot withstand.
What milling cutters are used with the MT3 / MT4 taper?
The MT3 or MT4 Morse taper of the KF series accepts: tapered shank cutters (with direct reduction in the spindle), tapered shank holders, ER32/ER40 collets for straight shank cutters. With the MT3→B16 reduction, the keyless chuck for standard drill bits is mounted. For face milling, face mill heads with a 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 turn the knob during operation. To switch from slow drilling on hard steel to fast milling on aluminum, it only takes 3 seconds instead of 2–3 minutes of machine downtime with a traditional belt-driven gearbox.
Are spare parts and assistance available?
Original Bernardo spare parts available with 3–5 business days shipping. Customer support available in Italian.
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 complete dimensions of the specific model.
