The fixed 45° angle is standard for typical mechanical engineering chamfering, while the continuous adjustment of the chamfer width from 0-4 mm in 0.1 mm increments allows for precise finish control. Its ability to work on internal radii up to 20 mm distinguishes it from fixed bench chamfering machines. The TiN-coated carbide inserts ensure superior durability compared to standard inserts and a clean finish on steel, stainless steel, aluminum, brass, and plastic. In Krollit customer workshops, it is chosen by mechanical workshops for post-cutting finishing, metal fabricators for chamfering edges for welding, and laboratories working on safety-critical metal parts where burrs are unacceptable.\u003c\/p\u003e\n\u003ch3\u003eIts place in the Bernardo range\u003c\/h3\u003e\n\u003cp\u003eIn the Bernardo chamfering machine range, the KFM 100 K is the entry-level model for manual use at 45°. The KFM 200 M chamfering machines (with linear guide) in the same range offer a chamfer width up to 10 mm and angle adjustment from 15°-45°, sized for heavy chamfers on panels and steel beams for welding. The difference is in purpose: the KFM 100 K is a quick finishing tool for removing burrs and edges on finished parts; the KFM 200 M is a preparation machine for welding seams in heavy fabrication. For most workshops, the KFM 100 K is the right tool for daily deburring; the KFM 200 M only makes sense if V-chamfers for welding on steel thicker than 6-8 mm are regularly performed.\u003c\/p\u003e\n\u003ch3\u003eKrollit logistics and support\u003c\/h3\u003e\n\u003cp\u003eBernardo shipping in 5-9 working days (7 days to Southern Italy).
