The Bernardo KFM 200 M / 230V portable chamfering machine offers a chamfer width of up to 10 mm at 45°, angle adjustment from 15°-45°, a 200 mm guide rail, a 0.55 kW single-phase 230V motor, and a speed of 2,800 rpm. This is the single-phase version of the KFM 200 M, identical in performance to the 400V three-phase version except for the power supply. Designed for weld seam preparation. Weight 11 kg. Manufactured in Austria, distributed in Italy by Krollit as an official Bernardo distributor since 2007.

Who uses the KFM 200 M and for what
The Bernardo KFM 200 M / 230V is the single-phase version of the professional portable chamfering machine for workshops without a 400V three-phase line. The technical specifications are identical to the 400V three-phase version: chamfer width up to 10 mm at 45°, adjustable angle 15°-45°, 200 mm guide rail. The 0.55 kW single-phase motor is functionally equivalent to the three-phase for intermittent use and moderate duration cycles; for prolonged continuous use, the three-phase version maintains torque better. In Krollit customers' workshops, it is chosen by small and artisanal metalworking shops with only a 230V single-phase line that need to prepare weld seams on steel panels and beams up to 10 mm effective chamfer width.
Its place in the Bernardo range
The KFM 200 M / 230V shares everything with the KFM 200 M / 400V except the power supply type. Same milling head, same guide rail, same weight (11 kg), same chamfering capabilities. The choice between the two versions is dictated exclusively by the electrical system available in the workshop: with a 400V three-phase line, the three-phase version is preferable for continuous use; with only a 230V single-phase supply, this version is the only one that can be installed. Below the KFM 200 M, the Bernardo chamfering machine range offers the KFM 100 K for finishing chamfers on small radii; above it are industrial chamfering machines with chamfer widths over 15 mm for heavy metalwork.

Who is the KFM 200 M for?
| Profile |
Compatibility |
Reason |
| Passionate hobbyist |
Not recommended |
Machine sized for professional weld preparation use. Even in the 230V version, the cost and 11 kg weight make it unsuitable for occasional hobby use. |
| Artisanal metalworking shop / blacksmith with only 230V line |
Recommended |
Single-phase version for workshops without a three-phase line. Same capabilities as the 400V version for intermittent use: chamfer up to 10 mm with angle adjustment 15°-45°. |
| Metalworking shop with intensive continuous use |
Adequate |
For prolonged continuous cycles (over 4 hours daily), the 400V three-phase version maintains torque better. If three-phase is available, it is preferable to choose it. |
Not recommended for: chamfers under 1 mm width (consider KFM 100 K); pieces with curved surfaces or angles not at 90°; prolonged industrial continuous use (prefer the KFM 200 M / 400V three-phase).

Frequently Asked Questions
Does it work on a standard 230V household outlet?
Yes. The 0.55 kW single-phase motor requires a standard 16A outlet. The power draw is manageable by a standard household/artisan meter.
The 0.55 kW motor draws peak currents of 1-1.2 kW, which can be handled by a standard 3 kW household meter. For prolonged continuous use, the average consumption remains well below the tripping threshold of a standard circuit breaker. For workshops with other machines running simultaneously, check the available power of the meter.
Is the performance the same as the 400V three-phase version?
For intermittent use, yes. For prolonged continuous use (over 4 hours), the three-phase version maintains motor torque better and manages heat more effectively.
The practical difference between single-phase and three-phase at this power level is limited. For artisanal and construction site use, the 230V version offers more than adequate performance. Only for continuous industrial cycles on hard steels does the difference become noticeable, with the three-phase reducing the frequency of cooling breaks.
Can I convert the 230V to 400V later?
No, the motor is dedicated. To switch from single-phase to three-phase, you need to replace the machine with the 400V version.
The single-phase and three-phase motors are completely different units, not interchangeable. The choice of version must be made based on the electrical system available at the time of purchase. If the workshop is undergoing electrical renovation with future installation of a three-phase line, it may be convenient to wait and purchase the three-phase version, which is more suitable for intensive use.
What power supply is required for an extension cord?
For extension cords longer than 5 meters, use a cable with a minimum cross-section of 2.5 mm² to avoid voltage drops. For long extension cords (over 20 meters), consider a 4 mm² cross-section.
The KFM 200 M / 230V with a starting current draw of 1.2 kW requires correctly sized extension cords to avoid voltage drops that would reduce motor torque. Thin (1-1.5 mm²) coiled extension cords typical of construction sites are not suitable for prolonged use of this machine: they cause cable overheating and performance loss.
How much does it weigh with the carrying case?
11 kg net without the case, approximately 13-14 kg with the carrying case. Manageable by one person for movement around a construction site.
The 11 kg weight is the working weight: the operator holds the machine with two hands during use. The carrying case makes it practical to move between construction sites. For sites with frequent transfers between work points, the KFM 200 M is sized to be easily carried by hand.
