Bernardo Drill-Milling Machine KF 25 PRO
The Bernardo KF 25 PRO drill-milling machine is a combined machine suitable for drilling, milling, and tapping. Thanks to its DC motor and 2-stage gearbox, it offers continuous speed regulation (50–3000 rpm) and optimal torque even at low speeds.
The 700 x 180 mm cross table, with finely machined surfaces and travels of 490 x 150 mm, ensures ample operating space and precision. The ±90° inclinable head allows for angled milling and chamfering, while the tapered roller bearings ensure high spindle concentricity (≤0.015 mm).
This model can optionally be equipped with automatic table feed and a 3-axis digital readout, further increasing productivity. Standard features include: digital display for spindle travel and speed, adjustable protection, EMC filter, and tool set.

Frequently Asked Questions
What is the difference between a pillar drill and a drill-milling machine?
A pillar drill only has vertical spindle movement and a rotating table — suitable exclusively for drilling. The drill-milling machine (KF series) adds dovetail guides on the X and Y axes, allowing 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 pillar drill cannot withstand.
What cutters are used with the MT3 / MT4 taper?
The MT3 or MT4 Morse taper of the KF series accepts: taper shank cutters (with direct reduction in the spindle), cutter holders with taper shanks, ER32/ER40 collets for cylindrical shank cutters. With the MT3→B16 reduction, a self-tightening chuck for standard drill bits can be mounted. For face milling, milling heads with the corresponding taper attachment 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 a traditional belt-driven gearbox.
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 complete dimensions of the specific model.
