Cone

The Multi-Purpose Bit for Cuticle and Nail Shaping

The Diamond Cone Bit is your new go-to for versatility. This nail bit has earned its place in the toolkits of top techs thanks to its ability to tackle a wide range of services, from cuticle exfoliation to shaping and cleaning the underside of the nail. Whether you’re using for a dry manicure or refining enhancements, the Diamond Cone Bit delivers smooth, flawless results every time.

Designed for Versatility and Precision

The Cone Bit’s tapered, elongated shape allows for excellent visibility and control, making it ideal for both natural nails and enhancements. Its narrow tip easily reaches tight spaces around the cuticle area, while the wider base offers efficient surface work. This makes it great for exfoliating the cuticle, cleaning under the free edge, refining sidewalls, and shaping product — all with one versatile tool.

Perfect for Dry Manicures

Like all diamond bits from Erica’s ATA, the Diamond Cone Bit is expertly crafted for dry manicure techniques and enhancement shaping. Using it dry means you can achieve cleaner, more detailed work without the interference of water or soft tissue, allowing for optimal precision and better adhesion of nail products. It’s a must-have for techs who prioritize both performance and nail health.

100% Natural Diamond for Superior Quality

Quality matters. The Diamond Cone Bit is made with 100% natural diamond, not fillers or composite materials. This ensures long-lasting sharpness, durability, and consistent performance across 150–300 services. 

Two Grit Options

The rounded, tapered shape of the Cone Bit is designed to be safe for both the nail plate (in medium grit) and surrounding skin. The coarse diamond grit options allows for greater exfoliation on thick or callused skin or shaping nail enhancements.
