The DC-1 (ISO 834/003) is a specialized "Depth Marker" or "Depth Cutter" bur.Unlike standard tapered burs, it features a unique tri-wheel or multi-cylindrical design.This geometry allows the bur to stop cutting once the designated depth is reached, effectively "taking the guesswork out" of crown and veneer preparations.These burs are manufactured using high-quality natural diamond grit bonded to a stainless steel profile body to ensure lasting sharpness and superior cutting ability.

Features
Self-Limiting Depth Control: The specialized wheels act as a built-in stop, allowing for precise, uniform depth channels (e.g., 0.3mm or 0.5mm) across the tooth surface.
Precision Veneer Prep: Specifically engineered for labial reduction, ensuring adequate space for restorative materials while preserving as much natural tooth structure as possible.
Friction Grip (FG) Shank: Designed with a standard 1.6 mm diameter shank to fit high-speed dental turbines.
Superior Bonding: Manufactured using modern galvanizing or brazing processes that maximize diamond exposure and ensure particles stay put during high-speed rotation.
Reduced Heat & Vibration: Computer-controlled engineering ensures true concentricity and balance, which minimizes vibration and potential damage to handpiece bearings.
Efficiency: Coarse or medium diamond grits allow for quick, clean cutting through tough enamel and ceramic structures.
