Who uses the BF 28 BDC and for what
Light fabrication workshops, repair shops, and mechanical laboratories use this drill-milling machine for small series production: drilling flanges and supports up to Ø28 mm, milling keyways on brackets, tapping up to M12 with a reverse pedal. In this machine, the DRO ES-12 V display allows for repeatable positioning on all 3 axes.
Its place in the Bernardo range
The Bernardo BF 28 BDC with DRO ES-12 V (intermediate version) is positioned in the mid-high range of Bernardo drill-milling machines. Above this machine, the range offers the BF 30 G with a 12-speed mechanical gearbox and the large BF 45 HSV / FM 45 HSV / FM 50 HSV for intensive work. Below the BF 28 BDC, the range offers models KF 25/26 and BF 25 Super with reduced drilling capacities (20-25 mm).
Krollit logistics and support
Bernardo shipping in 5-9 working days (7 days to the South). For original Bernardo spare parts, shipping 3-5 working days from Krollit warehouse. Customer support in Italian available for technical documentation, product sheets, and spare parts order management. Krollit has been an official Bernardo distributor since 2007.

Frequently asked questions
What are the drilling and milling capacities of the BF 28 BDC?
Steel drilling up to Ø28 mm, face milling up to Ø63 mm, end milling up to Ø20 mm.
The stated capacities refer to standard unhardened steels (e.g., C40, S235). For harder materials or alloy steels, the actual capacity may be lower: in this case, it is advisable to reduce the rotation speed and feed rate to avoid stressing the spindle and tools.
How is the spindle speed adjusted on the BF 28 BDC?
The machine features continuously variable speed in the range 100–1,500 / 200–3,000 rpm.
The Vario adjustment allows the speed to be finely adapted to the material and tool diameter without having to change belts or gears. For face milling soft steels, the lower range is typically used, while for small diameter holes in aluminum, the higher range is used.
What power supply and motor does the BF 28 BDC use?
0.75 kW motor (S1 continuous) / 1.1 kW (S6 intermittent) with 230 V power supply.
The motor operates with a standard 230 V single-phase power supply, found in all workshop and laboratory environments. The S6 40% rating indicates that the motor can deliver maximum power for intermittent cycles, while the S1 100% rating indicates the nominal power for continuous use.
What are the table dimensions, travels, and spindle taper of the BF 28 BDC?
Cross table 700 x 180 mm with X/Y travels of 500 / 215 mm, MT 3 spindle taper, spindle travel 67 mm.
The MT 3 spindle taper is an international standard: accessories (self-tightening drill chucks, milling chucks, reduction arbors) are commonly available. The table travels allow for machining parts that fall within the effective usable dimensions (X/Y travels net of clamping clearances).
How much does the BF 28 BDC weigh and what type of installation does it require?
The machine weighs approximately 130 kg and is designed for installation on a rigid base (optional accessory) or a sturdy workbench, with a 230 V electrical connection.
For transporting and positioning a 130 kg machine, the use of a pallet truck or light crane is recommended. The support bench must be sized for the weight of the machine plus the workpiece, ensuring flatness to avoid compromising accuracy.
