Diamond Nail Bit EXO Pro 2.3 mm — EXO professional manicure/cuticle tool

EXO Pro diamond nail bit with a 2.3 mm spherical head is a rotary manicure and pedicure tool designed for precise shaping, cuticle work and surface refining. The bit features a fine diamond-coated surface for controlled material removal on natural nails and nail enhancements. It is made to fit electric nail drills that accept standard bit shanks and is suitable for both professional salons and experienced home users who need durable, accurate tooling for daily nail maintenance and corrective work.

Advantages

The diamond coating provides consistent abrasion and long wear, reducing the need for frequent replacement. A 2.3 mm spherical head offers controlled contact area for delicate cuticle trimming and shaping around the nail edge without digging or tearing. The cylindrical shank is compatible with most electric files that accept standard bits, enabling quick bit changes during multi-step procedures. The fine grit finish allows smooth surface refinement and gentle removal of dead tissue or product build-up while preserving the nail structure.

Suitable for

• Precise cuticle removal and cleaning around the nail fold
• Shaping and smoothing natural nails and nail enhancements
• Refining surface texture before polishing or applying coatings
• Spot work for reducing product build-up and smoothing edges

How to use

Secure the diamond bit into the chuck of the electric nail drill according to the drill manufacturer's instructions. Start at a low speed setting and increase gradually as needed; use light pressure and keep the bit moving to avoid concentrating heat or removing excessive material. For cuticle work, approach gently at a shallow angle and make short, controlled strokes around the nail fold. For surface refinement, work across the nail in even passes until the desired texture is achieved. Clean the bit after use by brushing away debris and, if appropriate, using manufacturer-recommended disinfecting methods.

Usage recommendations

Use appropriate personal protective measures such as eye protection and dust extraction when operating an electric drill. Avoid excessive speed and pressure to prevent damage to the natural nail. Replace the bit when the diamond surface shows significant wear or reduced cutting performance.
