Buying guide

Which KMIZ drill bit should you choose?

Diamond and carbide bits serve different purposes. These criteria help you compare KMIZ models and distinguish abrasive grit, cutting teeth and cut direction.

Diamond or carbide: what changes?

Comparison of KMIZ diamond and carbide drill bits
MaterialMain useWhat the band describesCheck before use
DiamondPreparation, contours and nail folds, depending on shape and grit.Abrasive grit, from ultra fine to extra coarse depending on the model.Shape, diameter, grit and intended technique.
Tungsten carbideRemoval of gel, acrygel or acrylic and work on enhancement material, depending on the teeth.Tooth size, sometimes with an additional cut marking.Teeth, dimensions, direction of cut and material worked.

Colour alone is not enough: read the model name and specifications before use.

By task

Find the bit for your technique

01

Access nail folds

A diamond flame reaches narrow contours. Match its diameter and grit to your technique.

02

Work around the cuticle

A diamond ball suits localised work around the cuticle with controlled technique and suitable grit.

03

Remove enhancement material

A carbide bit selected for the material and tooth size supports the removal of enhancements.

04

Build a useful selection

Compare shapes, grits and dimensions to assemble complementary bits for your practice.

Read the bands

KMIZ colour codes explained

On diamond bits, colour indicates abrasive grit; on carbide, it indicates tooth size. Multiple bands require a separate reading.

Common KMIZ band references; verify the individual model
ColourCodeTypical grade

White is a diamond reference. Available grades vary by model; always consult the bit’s product page.

Special markings

Two bands or purple: what do they mean?

A combination of colours has a different meaning from a single band. Confirm the marking on the exact model.

Two different colours on diamond

These indicate an intermediate grit, such as yellow/red or red/blue.

Two identical bands

This marks KMIZ bits intended for left handed use. Check the rotation direction on the product page.

Purple with another colour on carbide

This indicates triple cut on relevant models. It does not by itself identify a left handed bit.

Choose a shape

Flame, ball, tulip or cone

Geometry determines the accessible area and technique. Diameter and length matter too.

Flame

For accessing sidewalls and nail folds, according to the selected size.

Ball

For localised contour work with an appropriate diameter.

Tulip

A flared profile chosen to suit the working area and technique.

Cone

For surfaces or enhancements, depending on the model’s material and teeth.

Use and care

Check, clean and maintain

Before use, inspect the bit, its fitting and shank compatibility with your handpiece. Match speed, pressure and rotation direction to the bit. Follow the manufacturer’s instructions for cleaning, disinfection and, where permitted, sterilisation.

Frequently asked questions

KMIZ drill bits FAQ

What is the difference between KMIZ diamond and carbide bits?

Diamond bits have an abrasive coating and are used, among other things, for preparation and contours. Tungsten carbide bits have cutting teeth and are commonly used for product removal. Select the model for the intended technique.

Which KMIZ bit is suitable for cuticles?

Diamond shapes such as the flame and ball are often chosen for nail folds and contours. Compare diameter and grit, and use an appropriate technique without excessive pressure.

Which bit should I use to remove gel or acrygel?

Explore tungsten carbide models intended for enhancement material. Tooth size, shape and cut direction should suit the product and your technique.

What do red and blue bands mean?

Red generally denotes fine and blue medium. On diamond this describes abrasive grit; on carbide it describes tooth size. Check the individual model.

What do two different coloured bands mean?

On a KMIZ diamond bit, two different colours indicate an intermediate grit, such as yellow/red or red/blue. Check the exact product description.

How do I identify a left handed KMIZ bit?

Two identical bands indicate KMIZ models intended for left handed use. Also check the name and rotation guidance before ordering.

What does a purple band mean on a carbide bit?

Alongside another colour, purple can indicate triple cut on certain KMIZ carbide bits. It does not automatically mean left handed; check the product page.

Do KMIZ bits fit every nail drill?

Compatibility depends in part on the shank and handpiece. Check the model’s dimensions and your machine specifications before use.

How should KMIZ bits be cleaned?

Follow the bit manufacturer’s instructions and your professional protocol: remove debris, clean, disinfect and, if permitted for the model, sterilise appropriately. Inspect before reuse.

Where can I find a KMIZ bit’s size?

Dimensions appear on each model’s product page. Compare head diameter, head length and shank against your technique and handpiece.
