Frequently Asked Questions
What grit size should I use for different materials?
Metal rough grinding (rapid removal): P40–P60. Intermediate metal sanding: P80–P120. Metal finishing: P150–P240. Wood rough grinding: P60–P80. Wood finishing: P100–P180. For aluminum, use specific aluminum belts with an open bond to prevent clogging. Do not mix belts used on metal with those to be used on wood.
Can the work surface be tilted for bevels?
Yes, on all models in the MS/BS/HV/BDSM range, the support surface is adjustable (typically 0°–45°) for grinding chamfers and angled surfaces. Check the maximum angle in the technical table of the specific model.
Are replacement abrasive belts available?
Yes. Original Bernardo abrasive belts in various grit sizes for all models in the range are available with 3–5 business day shipping. Specify length, width, and model when ordering.
Does the grinder have integrated suction outlet?
Yes — all models in the MS/BS/HV range of the S series have integrated suction (indicated in the name). Connect a dust extractor with adequate flow rate to the connection to maintain cleanliness in the environment and visibility during processing.
Is assistance available?
Original Bernardo spare parts available with 3–5 business day shipping. Italian customer support available.
