High-Precision Dental Rotary Diamond Burs (FG 1.6mm)
Our Dental High-Speed Diamond Burs are manufactured using vacuum-controlled multi-layer galvanic electroplating technology, bonding premium selected natural diamond crystals onto high-tensile, corrosion-resistant stainless steel shanks. Engineered for superior concentricity and cutting sharpness, they deliver smooth, chatter-free enamel reduction, cavity preparation, and margin beveling while preserving pulp vitality through reduced friction and thermal buildup[cite: 41].
Key Clinical Advantages & Features
- Multi-Layer Dense Diamond Coating: Uniform crystal distribution ensures sharp multi-point cutting surfaces remain actively exposed even under intensive tooth structure reduction.
- Precision CNC-Machined Stainless Shanks: Milled to tight tolerances (ISO 1797-1 standard Ø 1.60 mm), preventing chuck slippage and excessive wear on high-speed handpiece turbine spindles[cite: 40].
- Standardized International Color-Coding: Features distinct, autoclavable colored identification rings for immediate chairside recognition of cutting abrasiveness.
- Ultra-Low Rotational Vibration: Dynamic balance testing eliminates runout, providing tactile precision and protecting fragile preparation margins from chipping[cite: 41].
- Fully Autoclavable: Safe for repeated ultrasonic baths, thermal disinfectors, and autoclave cycles up to 135°C without peeling or corrosion.
