Bizopen Diamond Bur Tapered Round End 368-012 Standard Grit

The Bizopen Diamond Bur Tapered Round End 368-012 Standard Grit is a versatile combination instrument that delivers the tapered axial wall geometry of a tapered fissure bur with a rounded end that simultaneously creates a deep chamfer or rounded shoulder margin without the need for a separate margin-finishing instrument. The rounded end transitions smoothly from the tapered lateral body at a radius that produces a 1.0 to 1.5 mm deep chamfer — broader and more supportive than a standard chamfer — providing the robust margin geometry that posterior all-ceramic crown restorations require for long-term marginal integrity. Bizopen’s 180 grit standard diamond coating covers the complete tapered surface and the rounded dome end, allowing full preparation from coronal axial reduction through finish line establishment in a single instrument without instrument change. The tapered round end design is particularly efficient for complete-arch crown preparation where minimizing instrument changes reduces the total preparation time per tooth and decreases the potential for preparation geometry inconsistency that instrument changes can introduce when different instruments are used for axial reduction and margin preparation. The 1.2 mm maximum body diameter in this size provides access to anterior preparation zones and to narrow preparation spaces between adjacent teeth in tight dental arch geometries. The 6-degree taper provides the standard draft angle for indirect restoration seating. FG shank. ISO 806 314 166 524 012. Maximum diameter: 1.2 mm. Working length: 6.0 mm.
