The Bizopen Diamond Bur Tapered Fissure 847-016 Standard Grit is a precision tapered cylindrical diamond instrument designed for crown preparation, veneer preparation, and axial wall reduction where a consistent draft angle is the primary geometric requirement. The 1.6 mm maximum diameter tapered head with a 6-degree taper angle on each side delivers the 12-degree total draft that provides adequate retention for indirect ceramic and metal-ceramic restorations while remaining within the range of parallelism that prevents mechanical undercut during seating. Bizopen’s 180 grit standard diamond coating on the tapered fissure geometry provides the balanced cutting efficiency that crown preparation requires — fast enough for efficient axial reduction without the surface roughness that requires significant finishing instrumentation to correct before impression taking. The flat end of the tapered fissure geometry creates the horizontal shoulder or chamfer finish line in a single instrument stroke when the bur is angled correctly against the preparation margin, allowing efficient finish line establishment during the axial reduction stroke. The bur tip is rounded to prevent inadvertent pulpal floor gouging when the instrument contacts the axio-gingival angle. FG shank, 19 mm total length. ISO 806 314 110 524 016. Maximum working diameter: 1.6 mm. Taper angle: 6 degrees per side.
