Frequently asked questions
Which machine is it compatible with?
Check the title or technical data sheet for the machine model or connection indicated (e.g., DG 20 M, BSG 30 Pro, Bernardo HM 25).
Bernardo tools are original spare parts for the machines in the Krollit catalog. For compatibility doubts, contact customer support specifying the machine's serial number.
CBN or diamond grinding wheel: which one to choose?
CBN for sharpening drills and tools made of HSS, hardened, and case-hardened steels. Diamond ONLY for hard metal (carbide, HM).
CBN grinding wheels cut "cold" without dulling on HSS, maintaining the abrasive edge for a long time. Diamond grinding wheels should not be used on steel: the grains quickly dull, losing cutting ability.
What materials can it work with?
Depends on the tool's geometry and material: HSS for common steels, HM/carbide for hard steels, CBN for HSS and case-hardened steels, diamond for hard metal.
Cobalt HM inserts (HSSE) work up to HRC 65. CBN grinding wheels cut steels with HRC 55-70, maintaining concentricity over time. For cast iron, consider green silicon carbide grinding wheels.
How should it be stored and maintained?
In a dry environment, protected from impacts and oxidation. Grinding wheels should be dressed periodically with a diamond bar.
For abrasive grinding wheels, proper storage and periodic dressing preserve the cutting geometry. For HM inserts, storage in the original box is sufficient.
Is it an original Bernardo spare part?
Yes, Krollit has been an official Bernardo distributor since 2007 and only supplies original tools from the manufacturer.
Non-original compatible tools may have out-of-spec tolerances and compromise machining precision. Shipping 3-5 business days.
