Ceramic vs Tungsten Carbide: Thermal Dynamics & Flute Geometry
Tungsten carbide bits are machined from ultra-dense industrial carbide steel. Their sharp, spiraled or cross-cut flutes physically slice through hard gel, polygel, and acrylic enhancements like microscopic razor blades.
Ceramic bits, sculpted from zirconium oxide ceramic, operate through high-speed micro-friction. Ceramic has a much lower thermal conductivity coefficient than metals, remaining significantly cooler on the nail surface during high-RPM gel polish removal.
The Universal Color-Coded Grit Collar Standard
Professional bits follow an international color band system: Yellow (X-Fine), Red (Fine), Blue (Medium), Green (Coarse), and Black (X-Coarse).
Never touch bare natural nails with anything coarser than a Red (Fine) band. Blue is reserved for gel shaping, while Green and Black are dedicated strictly to bulk debulking of thick artificial enhancements.
