Frequently Asked Questions
What can the 400 V (150-2000-br-2-400v) grind?
Stainless steel, aluminum, metal alloys and (in some models) also wood with appropriate abrasive belts.
A specific grit of abrasive belt is used for each material: 60-80 for roughing, 120-180 for finishing, 240+ for pre-polishing.
What abrasive belt sizes does it take?
See "Belt dimensions" in the technical table: typically from 75x2,000 mm to 150x2,500 mm.
Belts are consumables: Krollit supplies original Bernardo belts in various grit sizes to optimize the finish.
Is the belt speed adjustable?
Professional models offer Vario or multi-step speeds (typically 4-8 steps).
High speeds (>20 m/s) for stainless steel and finishing, low speeds (<10 m/s) for wood and soft materials to prevent burning.
Does it have integrated dust extraction?
Professional models offer dust extraction ports for grinding dust.
Extraction is essential for stainless steel (respirable dust) and for wood (fire risk from sparks). Check the diameter of the connection for linking to a centralized system.
How much does the machine weigh?
See "Weight" in the technical table: typically 50-200 kg for bench and pedestal models.
Pedestal models require floor mounting, bench models are installed on a sturdy bench of adequate size.
