Bizopen Diamond Bur Flat End Cylinder 836-020 Coarse Grit

The Bizopen Diamond Bur Flat End Cylinder 836-020 Coarse Grit is the large-diameter instrument in Bizopen’s flat end cylinder range — a 2.0 mm diameter coarse grit preparation instrument designed for full-arch crown preparation of posterior teeth where the larger head diameter reduces preparation time by covering greater axial surface area per stroke and producing wider, flatter preparation floors in a smaller number of instrument passes. The 2.0 mm body diameter is the largest in Bizopen’s FG-shank cylinder bur range, providing wide flat-surface contact appropriate for the broad axial walls of mandibular and maxillary first molars where the mesio-buccal, disto-buccal, and lingual axial surfaces each present substantial area requiring systematic reduction. At 100 grit coarse diamond, the 836-020 delivers the highest material removal rate in the Bizopen cylinder bur range — appropriate for situations where significant bulk axial reduction is required on large posterior teeth with heavy existing restoration or extensive carious involvement that has altered the natural tooth crown geometry. The 2.0 mm diameter flat end establishes the preparation floor at the correct preparation depth across the full axial extent of each preparation wall in fewer strokes than narrower instruments require. The instrument is intended as a coarse reduction instrument only — subsequent standard grit and fine grit finishing instruments are required to achieve the preparation surface quality needed for impression taking.
