Key Components and Features

Quantity and Assortment
The kit includes 40 abrasive polishing discs, systematically divided into four distinct grit grades. This allows for a predictable, step-by-step polishing sequence from gross reduction to final high-gloss finishing.

Grit Sequence (Color-Coded System)

Coarse (Blue)
Used for gross reduction and initial contouring of restorative materials.

Medium (Green)
Designed for refining contours after the coarse shaping stage.

Fine (Yellow)
Used for initial finishing and surface smoothing.

Superfine (White)
Intended for achieving a high-gloss, natural-looking final polish.

Disc Design

Diameter
The specific catalogue number 1.072 typically corresponds to the largest disc diameter of 16 mm, making it ideal for broad surface coverage on large restorations and occlusal surfaces. Other commonly available sizes include 10 mm, 12 mm, and 14 mm.

Material
The discs are manufactured from a thin polymer backing coated with abrasive material, usually aluminum oxide or synthetic diamond powder, ensuring efficient and controlled polishing.

Flexibility
The discs are highly flexible, allowing them to easily adapt to both convex and concave tooth surfaces for precise finishing.

Mandrel (No. 1.121 – RA Type)

The kit includes a reusable stainless steel mandrel (No. 1.121, RA type). This component securely holds the single-use discs and transfers rotational power from the low-speed contra-angle handpiece, ensuring stable and safe operation.
