Round End Taper Diamonds

Round end taper diamonds — the 856 family and its relatives — are the single most-used crown preparation shape in dentistry: axial reduction and a rounded chamfer margin from one instrument. This collection covers the full grit ladder from super coarse bulk reduction to extra fine margin refinement, in standard and long versions.

Busch’s diamond coating consistency means predictable cutting from first prep to last, and the shared DIN figure system means your favorite 856 size maps directly from any other German brand — see the comparison chart below.
