The 200 mm linear guide rail ensures that the milling head slides stably and repeatably, producing uniform chamfers over long lengths without the undulations or variations typical of free-hand chamfering machines. The 15°-45° angle adjustment allows the chamfer geometry to be adapted to the required welding type: open angles for full penetration welding, closed angles for filler welds. In Krollit customers' workshops, it is chosen by heavy metal fabricators, steel structure construction workshops, shipyards, and repair shops that require precise chamfers on workpieces up to 10 mm effective width.\u003c\/p\u003e\n\u003ch3\u003eIts place in the Bernardo range\u003c\/h3\u003e\n\u003cp\u003eThe KFM 200 M is available in both a 400V three-phase version (this model) and a 230V single-phase version. The specifications are identical: only the power supply changes. The 400V version is preferable for continuous professional use due to the more consistent motor torque; the 230V version is the only choice for workshops without a three-phase line. In the Bernardo chamfering machine range, the KFM 200 M occupies the professional segment for preparing weld seams on light-to-medium fabrication. Below it is the KFM 100 K (free-hand, chamfer up to 4 mm) for quick finishing; above it are industrial chamfering machines with chamfer widths over 15 mm and guide rails up to 500 mm. For most fabrication workshops that do regular welding, the KFM 200 M is the standard preparation machine.\u003c\/p\u003e\n\u003ch3\u003eKrollit Logistics and Support\u003c\/h3\u003e\n\u003cp\u003eBernardo shipping in 5-9 business days (7 days to the South).
