Who uses the KSM 500 S and for what
The Bernardo KSM 500 S chamfering machine is an electric tool for deburring and chamfering edges on metals: 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. At 37 kg, it is portable and can be used on a workbench or handheld. In Krollit 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 Bernardo KFM 100K, KFM 140, KFM 175, KFM 200M, and KFM 500M chamfering machines?
KFM 100K: fixed 45°, 4 mm chamfer, 100 mm guide, 720W, 3.5 kg. KFM 140: fixed 45°, 3 mm chamfer, 140 mm guide, 720W, 3.8 kg. KFM 175: fixed 45°, 5 mm chamfer, 175 mm guide, 1400W, 5.2 kg. KFM 200M: variable 15°–45°, 10 mm chamfer, 200 mm guide, 550W (230V or 400V), 11 kg. KFM 500M: variable 15°–45°, 5 mm chamfer, 500 mm guide, 550W (400V), 33 kg. The choice depends on the chamfer width, guide length, and required angle.
Are the TCT inserts interchangeable between models?
No. Each model uses specific geometry inserts. Original Bernardo spare inserts are available with 3–5 working day shipping. Please specify the exact model when ordering.
Does it work on aluminum and stainless steel?
Yes. Bernardo chamfering machines work with 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 micrometer ring with 0.1 mm graduation—rotate to the desired width and lock. The 0.1 mm precision ensures repeatability on series of identical parts.
Does the chamfering machine also work on curved angles?
The 500 mm guide is designed for chamfers on straight edges. For small internal radii (curves, holes), check the minimum workable radius with Krollit for this specific model.
