Professional nail sander Nail drill bits

1. Identify the stage and material

First identify the working area and material: natural nail, surrounding area or artificial coating. For precise preparation or finishing, consult diamond bits suited to that stage. For reducing or removing an artificial enhancement, consider carbide references. Each bit's product instructions take priority over a general rule.

2. Choose a diamond bit

Compare shape and abrasiveness rather than relying on color alone. A narrow flame, for example 1.8 × 8 mm or 2.3 × 10 mm, has a different contact surface from a ball, tulip or barrel. The diamond references on this page cover several areas and abrasion levels; choose according to your technique, control and the product instructions.

3. Choose a carbide bit

Carbide teeth cut away artificial material. A 5 or 6 mm rounded barrel and a narrow cone differ in working surface and access. Compare the tooth pattern, diameter and active length before choosing a bit for gel, acrygel or removal. A more aggressive cut is not automatically suitable for every area.

4. Compare shapes and dimensions

Flame and olive shapes offer targeted access; ball, tulip and barrel shapes change the contact surface; cone and rounded barrel shapes serve other movements on artificial material. Dimensions in millimeters describe the head, not a safety level. Check the available space and keep the bit moving in a controlled way without prolonged pressure in one spot.

5. Read grit and cutting indicators

Colors are indicators within the KMIZ range, but the same mark does not make different materials or shapes interchangeable. Among the listed references, yellow and red generally indicate finer levels than blue; purple and green appear on stronger cutting levels depending on the family. Combined rings require reading the specific product page. Never infer a bit's use from color alone.

6. Check rotation direction

Some references are intended for left-handed use, including carbide cone #117975 and several diamond Tornado flames. Check the direction specified on the product page and your device before use. Reversing the motor does not replace a bit designed for that direction when the manufacturer specifies a particular rotation.

7. Check compatibility and speed

Before fitting a bit, check the shank diameter, chuck and device manufacturer's instructions. Follow the speed range and rotation direction for the particular reference; do not use one setting for every bit. Apply measured pressure and stop if you notice heat, unusual vibration or discomfort.

8. Clean and replace

Remove debris after every service and follow the manufacturer's procedures for cleaning, disinfection, sterilization where applicable, and drying for the material and equipment. Inspect the teeth or abrasive surface regularly and replace worn or damaged bits. A kit helps organize your tools, but each piece still needs an individual check.
