    Factors Affecting Diamond and CBN Grinding Wheel Prices

    Updated: February 26, 2024 Published: September 22, 2023

    What factors influence the price of a grinding wheel? Probably more than you may think! When evaluating price, some of these factors will be obvious while others are sometimes unexpected. To help you gain a better understanding, we’ve put together an easy reference guide below.

    Obvious factors

    Diameter of the wheel – The larger the wheel, the more costly.

    Thickness of the abrasive sectionA thicker wheel contains more abrasive, making it more expensive

    Depth of the abrasive section – As with thickness, the greater the depth of the abrasive section, the more a wheel will cost. Increased depth results in more material being used.

    QuantitiesMost manufacturers use the “buy more, save more” model. The more abrasive and resin that can be mixed in one batch, the more cores that can be made. A larger quantity of one specific wheel typically decreases the cost of materials.

    Unexpected factors

    Concentration of the abrasiveA higher concentration of C100 or C125 will increase the cost of the wheel; but for some applications, C125 is necessary to ensure wheel performance. Concentration refers to the Carats / cubic centimeter.

    Wheel bondSome bonds are more expensive than others. The more costly bonds include metal bonds, poly bonds, hybrid bonds, vit bonds, electroplated and vacuum-brazed.

    Grit size – Fine grits (400 and over) are priced higher.

    Tight Tolerances – Price will increase if the application or customer requires extremely tight tolerances.

    Core Material – The material of the core can affect the pricing in two ways:

    Bakelite is typically the cheapest and the lightest so it saves on freight.

    Steel is more expensive and the heaviest, therefore increasing shipping costs.

    So How Much is a Diamond or CBN Wheel Going to Cost?

    As you can see, the cost of a superabrasive wheel can vary greatly depending on the type and application. The above points will hopefully aid you in assessing the “total cost” of both pre-stocked and custom grinding wheels. Remember that your investment in a grinding wheel doesn’t only include the wheel itself; it also includes the value your wheel provides over time.
