Frequently asked questions
Which machine is it compatible with?
Check the title or technical sheet for the machine model or attachment 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 doubts about compatibility, contact customer support, specifying the machine's serial number.
CBN or diamond grinding wheel: which to choose?
CBN for sharpening HSS drill bits and tools, hardened and case-hardened steels. Diamond ONLY for carbide (widia, HM).
CBN wheels cut "cold" without rounding on HSS, maintaining the abrasive edge for a long time. Diamond wheels should not be used on steel: the grains quickly round off, losing cutting ability.
What materials can it work on?
It depends on the tool's geometry and material: HSS for common steels, HM/carbide for hard steels, CBN for HSS and case-hardened materials, diamond for carbide.
Cobalt HM inserts (HSSE) work up to HRC 65. CBN wheels cut HRC 55-70 steels, maintaining concentricity over time. For cast iron, consider green silicon carbide wheels.
How to store and maintain it?
In a dry environment, protected from impacts and oxidation. Grinding wheels should be dressed periodically with a diamond stick.
For abrasive 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 supplies only original manufacturer tools.
Compatible non-original tools may have out-of-spec tolerances and compromise machining precision. Shipping 3-5 business days.
