PRODUCT REFERENCE CATALOG

# NIC Diamond Burs Reference

This reference index of the NIC diamond bur range is compiled from the manufacturer's 2025 catalog. The main figure for each shape is a schematic drawing generated from the stated catalog dimensions, not a traced or photographed product; where the catalog prints a product photograph for a shape, it is shown alongside and credited to the manufacturer. The manufacturer catalog serves as the source for all reported dimensions and designations.

 63 ISO Shapes 70 Shape Blocks 199 Diameter Variants 6 ISO Grit Grades

Explore ISO shapes, working-end diameters, lengths, cone angles, and availability matrices across the six grit grades. Each silhouette is drawn from the diameter, length and cone angle the catalog states for that instrument; the profiles themselves are schematic, so treat them as shape guides rather than scale reproductions.

## ISO Grit Classification & Colour Rings

6 grit categories, listed with the particle-size ranges and identification ring colours exactly as the manufacturer's catalog prints them. Grit size is one element of the ISO 6360-1 instrument code; the ranges and colours shown here are the catalog's statements, not quotations from the standard.

| Code | Ring | Designation | Particle Size | Catalog Stated Intended Use |
| --- | --- | --- | --- | --- |
| SC | black | Super coarse | 150~180 µm | Used for very quick reduction and removal of old fillings. |
| C | green | Coarse | 125~150 µm | Used for quick reduction and pretrimming. |
| M | blue | Medium | 106~125 µm | Used for universal trimming of the tooth structure. |
| F | red | Fine | 53~63 µm | Used for fine grinding of preprepared tooth surfaces. |
| SF | yellow | Super-fine | 20~30 µm | Used for finishing composite fillings and filling margins. |
| UF | white | Ultra-fine | 10~20 µm | Used for smoothing composites. |

## How the Order Code Works

Catalog SKUs follow the structured grammar <grit><NIC shape>-<ISO diameter>. The ISO diameter code reflects the working-end diameter in tenths of a millimetre.

Example Order Code:M805-010

MGrit Code

Medium grit (106~125 µm), blue ISO ring

805NIC Shape Number

Inverted cone profile (ISO 010 family)

\-010ISO Diameter Code

1.0 mm working-end diameter (10 × 0.1 mm)
