What this operative carbide bur is for
The FG170L High Quality Taper tungsten carbide bur is designed for tapered cavity walls, proximal box refinement, and crown or restoration adjustment in chairside operative and restorative workflows.
- Cuts tooth structure and restorative materials with controlled, predictable handling.
- Supports cavity preparation, crown and bridge adjustment, and filling refinement according to the bur shape.
- Helps clinicians maintain smoother cutting and longer bur life during repeated daily use.
- Best for cases where preparation control and edge retention matter.
Choose the right operative carbide bur quality for tooth preparation
For smoother chairside cutting, steadier control, and longer bur life during preparation and adjustment, High Quality is the better long-term choice.
