Product information

Traditional diamond burs often suffer from reduced efficiency and rapid wear when cutting zirconia because its hardness (≈13 GPa) is significantly higher than that of natural enamel. This super coarse bur (typically identified by a black color band) utilizes a unique bonding technology and high-grade diamond particles to maintain aggressive cutting action without the overheating or "clogging" common in standard burs.

Features

Dual-Action Grinding: As highlighted in the provided image, these burs are designed for "Coarse & Smooth cutting at the same time." The large, super-coarse diamond particles handle the heavy material removal, while the secondary layers ensure the resulting surface remains relatively refined.
Natural Diamond Coating: Many premium zirconia burs use natural diamonds, which possess a more uniform crystal structure and superior bonding strength compared to synthetic alternatives. This results in roughly 39% higher cutting efficiency when working with high-hardness materials.
Heat-Reduction Technology: Designed to work with copious water irrigation, the grit arrangement helps dissipate heat rapidly, which is critical to preventing micro-fractures in the zirconia restoration or thermal damage to the tooth pulp.
Extended Lifespan: The diamond particles are embedded deeply into a metal matrix (often via nickel sulfamate plating), providing better particle retention and a lower wear rate even during the most demanding crown-sectioning procedures.
Standard Compatibility: Features a Friction Grip (FG) shank with a standard 1.6mm diameter, making it compatible with all professional high-speed dental handpieces.
