NTI C850-012 Coarse Round End Taper Diamond Bur FG – NTI

Specification:

• Manufacturer Code: C850-012
• Brand: NTI
• Method: Coarse Grit Round End Taper Diamond Bur, Friction Grip (FG)
• Packaging: Pack of 5
• Usage: Crown & Bridge Preparation / Axial Wall Reduction / Chamfer Margin Definition / Gross Material Removal

The NTI C850-012 is a coarse grit, round end taper diamond bur in a standard friction grip (FG) shank designed for efficient axial wall reduction and chamfer margin preparation during crown and bridge procedures. The round end taper geometry combines a convergent tapered profile with a rounded tip for controlled axial wall preparation and smooth chamfer margin definition, minimizing the risk of sharp internal line angles at the preparation base. The coarse grit delivers aggressive material removal for rapid initial tooth structure reduction. Each pack contains 5 burs.

Key Features:

• Round End Taper Shape: The convergent tapered profile with rounded tip provides efficient axial wall reduction and smooth chamfer margin definition, supporting natural, flowing preparation contours and minimizing the risk of sharp internal angles or stress concentration points at the preparation base.
• Coarse Grit: Delivers aggressive cutting efficiency for rapid gross axial wall reduction and chamfer margin preparation, making it well-suited for the initial heavy reduction phase of crown and bridge preparation procedures.
• Friction Grip (FG) Shank: Standard normal-length friction grip shank provides secure, stable seating in high-speed handpieces, ensuring reliable retention and consistent rotational performance throughout the preparation procedure.
• Size 850.012: The 850.012 dimension provides a narrow working head diameter suited for precise axial wall preparation and chamfer margin definition across a range of anterior and posterior tooth preparation indications requiring controlled taper and minimal bulk reduction.
• Pack of 5: Each package provides five burs for convenient clinical restocking, supporting routine instrument replacement to maintain optimal cutting efficiency and consistent preparation results.
