Who uses the KFM 140 and for what
The Bernardo KFM 140 chamfering machine is an electric tool for deburring and chamfering metal edges: it removes burrs from cutting, punching, and drilling, creating a precise 45° chamfer that eliminates dangerous sharp edges and prepares surfaces for welding or treatment. Weighing 3.8 kg, it is portable and can be used on a workbench or handheld. In Krollit's customers' workshops, it is used by metal fabricators, blacksmiths, and workshop operators for systematic deburring after cutting.

Frequently Asked Questions
What is the difference between the Bernardo KFM 100K, KFM 140, KFM 175, KFM 200M and KFM 500M chamfering machines?
KFM 100K: 45° fixed, 4 mm chamfer, 100 mm guide, 720W, 3.5 kg. KFM 140: 45° fixed, 3 mm chamfer, 140 mm guide, 720W, 3.8 kg. KFM 175: 45° fixed, 5 mm chamfer, 175 mm guide, 1400W, 5.2 kg. KFM 200M: 15°–45° variable, 10 mm chamfer, 200 mm guide, 550W (230V or 400V), 11 kg. KFM 500M: 15°–45° variable, 5 mm chamfer, 500 mm guide, 550W (400V), 33 kg. The choice depends on the chamfer width, guide length, and required angle.
Are TCT inserts interchangeable between models?
No. Each model uses inserts of a specific geometry. Original Bernardo replacement inserts are available with 3–5 working days shipping. Please specify the exact model when ordering.
Does it work on aluminum and stainless steel?
Yes. Bernardo chamfering machines work on steel, stainless steel, aluminum, and non-ferrous metals. For stainless steel, reduce the feed rate. For aluminum, use a specific lubricant to prevent aluminum buildup on the inserts.
How is the chamfer width adjusted?
Adjustment is made via a micrometric ring with 0.1 mm graduation – rotate to the desired width and lock. The 0.1 mm precision ensures repeatability on identical series of parts.
Does the chamfering machine also work on curved angles?
The 140 mm guide is designed for chamfering straight edges. For small internal radii (curves, holes), check the minimum workable radius with Krollit for this specific model.
