Whitney Tapered Diamond Bit – Medium Grit (2.5 × 10mm)

The Whitney Tapered Medium is a versatile diamond bit designed for precise overlay refinement, edge work, and cuticle care. With a flat tapered profile, 2.5mm diameter, and 10mm working length, it balances efficiency and precision while giving you full control over the nail surface.

The medium diamond coating provides balanced abrasion — strong enough for overlay refinement and stubborn cuticle buffing, while still offering smooth, even results.

How to Use

Preparation

• Sterilise before use

• Insert into 3/32” chuck, test at low RPM before service

RPM Range

• Overlay & edge refinement: 10,000–20,000 RPM

• Cuticle buffing: 5,000–8,000 RPM (gentle, low speed)

Techniques

• Hold at a 15–30° angle, use light unidirectional strokes

• Work in ≤3 second passes per area to prevent heat buildup

• Use flat top for free edge refinement, tapered sides for curves

Safety & Care

⚠ Do not use excessive pressure (may cause heat or damage)
⚠ Avoid prolonged contact in one spot
⚠ Lower RPM for sensitive clients

• Clean immediately with nylon brush

• Disinfect in 70% alcohol or approved solution

• Autoclave safe for full sterilisation

• Replace once grit dulls or surface wears
