Wear (i. e. abrasion resistance), service life and cutting performance are important quality factors. Abrasive agents (aluminium oxide, silicon carbide, diamond, cubic boron nitride (CBN), etc.) and bonding (metal, synthetic resin or rubber) are characteristics composition. The following tendencies can be taken into account for choosing the appropriate material for a specific application:

Aluminium oxide (Al₂O₃) with synthetic resin bond for all steels. Depending on hardness, optimized binders are used.

Silicon carbide (SiC) for soft and medium-hard non-ferrous metals as well as hard non-metallic materials (glass, stone).

Diamond (C) for hard ceramic materials, ceramic composites and geological materials (rocks).

Boron nitride (CBN – Cubic Boron Nitride) for hard and tough Co- and Ni-based alloys, hard metals, hard composite materials, and hard to very hard carbon steels.

The grain size of the abrasive in the cutting wheel is an aspect that must not be neglected in metallographic sample preparation. It should be between 45 and 180 µm and will result in a surface that allows further metallographic preparation without removal-oriented planar grinding, if all parameters are set correctly. A very fine grain size is recommended when using thin wheels. A fine grain size is also important if burr-free sectioning is required. The degree of hardness of the wheel itself does not impact the hardness of the abrasive grains, but rather the hardness of the bond, i. e. about the resistance of the individual abrasive grain to breaking out of the bond material.

A softer bond should be used for large-area contact points. This also ensures that worn abrasive grains are broken out. This type is also well suited for heat-sensitive materials.

In the case of smaller contact areas, a harder and more stable wheel material is suitable. Those are also used for sectioning tubes and profiles. The advantage here is that it has less contact with the workpiece since the wall thickness is usually small.
