The single most common cause of premature bur failure is running an abrasive against a material it was never bonded for. Diamond grit shatters monolithic zirconia efficiently but glazes over on acrylic; carbide cuts alloy cleanly but chips against sintered ceramic; silicon carbide is made for base metal and will burnish rather than cut a precious alloy. This page sorts the Busch range by substrate so the choice is made once, correctly. Where a material appears in both clinical and laboratory contexts — zirconia especially — both sets of instruments are listed, since chairside adjustment and bench finishing call for different grit progressions.
