Bernardo Mill Drill KF 28 Top – Compact, versatile
The Bernardo KF 28 Top mill drill is a compact and precise machine, suitable for drilling, milling, and threading operations. The 2-stage gearbox with continuously variable speed (50–2600 rpm) ensures excellent power transmission and perfect adaptation to every type of material.
The 700 x 180 mm cross table with 490 x 150 mm travel and the ±90° tilting head allow for easy and precise angular machining and chamfering. The DC motor provides optimal torque even at low speeds, while the dovetail guides on X, Y, and Z axes, adjustable with gibs, guarantee stability.
With speed and spindle travel digital display, adjustable protection, EMC filter, and LED light included, the KF 28 Top is the compact and efficient choice for workshops and laboratories.

Frequently Asked Questions
What is the difference between the KF series and the BF/FM series in the Bernardo range?
The KF series (KF 16, KF 20, KF 25, KF 28) is the compact range: smaller tables, MT2/MT3 tapers, suitable for workshops with limited space and small-to-medium-sized operations. The BF series (BF 25, BF 30, BF 35, BF 40, BF 45) and FM series (FM 40, FM 45, FM 50, FM 55) are the professional versions: larger tables, MT3/MT4 tapers, more powerful motors, greater travel — for medium-sized parts in continuous production. The FM series has a 360° tilting head which the KF does not.
What do the suffixes "Vario" and "HSV" mean?
Vario: continuously variable spindle speed without changing belts. HSV: spindle head with tilt from -90° to +90° (Head Swivel Variable). BDC: integrated 3-axis digital position display (Digital Readout). The combination HSV + Vario is the most flexible configuration for workshops working with different materials and geometries.
Is the 3-axis DRO included as standard or is it an option?
It depends on the model. Models with "BDC", "DT 40", "ES-12V" or "with 3-axis display" in the name include the digital display as standard. Models without this designation do not include it — it is available as an optional accessory. Please check the specific model description.
Are spare parts available?
Original spare parts available with 3–5 business days shipping. Customer service available in Italian.
How much space is needed in the workshop for the BF/FM series?
BF and FM milling machines are stationary workshop machines — not portable. Consider space for X and Y axis travel plus at least 60 cm clear space on each side for safe operation. Contact Krollit for full dimensions of the specific model.
