Frequently Asked Questions
Which machine is it compatible with?
Check the machine model or connection indicated in the title or technical data sheet (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 to choose?
CBN for sharpening HSS, hardened, and case-hardened steel drills and tools. Diamond ONLY for carbide (widia, HM).
CBN grinding wheels cut "cold" without dulling on HSS, maintaining their abrasive edge for a long time. Diamond grinding wheels should not be used on steel: the grains quickly dull, losing their cutting ability.
What materials can it work with?
It depends on the tool's geometry and material: HSS for common steels, HM/widia for hard steels, CBN for HSS and case-hardened steels, diamond for carbide.
HM cobalt inserts (HSSE) work up to HRC 65. CBN grinding wheels cut HRC 55-70 steels, maintaining concentricity over time. For cast irons, consider green silicon carbide grinding wheels.
How is it stored and maintained?
In a dry environment, protected from impact and oxidation. Grinding wheels should be dressed periodically with a diamond stick.
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 manufacturer tools.
Compatible non-original tools may have out-of-spec tolerances and compromise machining precision. Shipping in 3-5 business days.
