All-in-One Power for Professional Nail Technicians
Streamline your e-file work with the Kupa 3/32" 3-in-1 Carbide Bit (Coarse)—a premium, American-made bit designed for maximum versatility and efficiency. This innovative tool combines three essential techniques into a single bit, making it a must-have for professionals seeking speed, precision, and flawless results.
Three Functions, One Bit
With its long tapered barrel and expertly engineered carbide construction, this bit performs seamlessly across the three most common services:
-
Cuticle detailing: Its slender, tapered shape allows you to safely and accurately clean around the cuticle area without causing damage to the natural nail.
-
Surface shaping & shortening: The coarse grit makes shaping and reducing acrylic or hard gel product faster and more controlled.
-
Under-nail cleaning: The fine tip easily reaches tight spaces beneath the nail to bevel and smooth with precision.
Whether you're doing full sets, fills, or gel polish removal, this bit helps you work smarter—not harder.
