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 doubts about compatibility, contact customer support, specifying the machine's serial number.
CBN or diamond 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 wheels cut "cold" without blunting on HSS, maintaining their abrasive edge for a long time. Diamond wheels should not be used on steel: the grains quickly become round, losing their cutting ability.
What materials can it work on?
Depends on the geometry and material of the tool: 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 wheels cut steels HRC 55-70 while maintaining concentricity over time. For cast iron, consider green silicon carbide wheels.
How is it stored and maintained?
In a dry environment, protected from impacts and oxidation. Grinding wheels should be periodically dressed with a diamond dresser.
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 only supplies original tools from the manufacturer.
Non-original compatible tools may have out-of-specification tolerances and compromise the precision of the work. Shipping within 3-5 working days.
