As it is important to select the optimum diamond abrasive particle for any particular application and working conditions, Element Six has developed an indicator system for its synthetic diamond series which helps customers identify the right product within each range for their particular tooling solution. This informtion is in our brochures that can be downloaded from the Literature Tab.
Product Range
SDB 1000 Series
This is the principal product range offered by Element Six and is a suite of products to satisfy a wide variety of application areas. The SDB 1000 series is manufactured by a synthesis process that uses nickel-based alloys. The synthesis yields bright yellow crystals with dot-type nickel-iron inclusions that have high thermal stability and excellent cosmetic appearance. The diamond abrasive particles produced are largely cubo-octahedral and this structure is characterised by particular wear and particle breakdown characteristics.
The SDB1000 series encompasses 1125, 1100, 1085, 1075, 1065, 1055, 1045 and 1025. This graded series of products means that it extends from the SDB112, which is a highly crystalline, highly thermally stable product to the SDB1025 is a friable, less crystalline products. These products are suitable for a wide range of sawing, drilling and grinding applications in stone and construction
SDB plus series
This is a complementary series to the standard SDB range of coarse abrasive particles, and has been designed as a successor to Element Six’s cobalt-based SDA Plus series. The range combines the distribution properties of the SDA Plus series with the benefits of the SDB range. Currently there are seven products with the range, the 100+, 85+, 75+, 65+, 55+, 45+ and 25+. It allows customers with tooling solutions built on the SDA Plus range to migrate easily and with confidence to the SDB plus family.
DSNAD series
As another series complementary to the SDB1000 series, DSNAD is a successor to the DSN range. Again, while processed to DSN specifications of size, strength and thermal stability, Element Six is able to offer customers the benefits of using the advanced nickel alloy catalyst synthesis technology employed in its successful SDB series while maintaining the essential crystal structure features and characteristics of the previous DSN range. Currently this range is available in seven different sizes.
Maxigrit
Developed for demanding heavy duty sawing and oil & gas applications, Maxigrit is a range of thermally stable products available in defined sizes. It is available in three grades from medium strength to premium strength covering seven sizes. Defined in stones per carat the range supports the manufacture of tools with consistent concentrations.The product range offers high thermal stability and so permits exposure to long sintering cycles and high temperatures.
Coated and clad products

Element Six has developed a range of coated and clad products to enhance the performance of diamond abrasive products in tooling solutions. Using an active coating technology, it creates a strong chemical bond between the diamond surface and the metal coatings.
Coated products are designed to improve the cost/performance ratio in high performance tools through the increased diamond retention due to the formation of a chemical/metallurgical bond between diamond and matrix. Coatings and cladding offer increased diamond protection – as the coating can prevent harmful matrix elements from graphitising the diamond.
Element Six offers three chemically-bonded coatings that are compatible with a range of bond formulations:
- SDBTC - for high copper or pre-alloyed bonds
- SDBTF - for bonds with high iron, cobalt or nickel
- SDBTB - for infiltration/liquid phase sintering
The SDBTC series is particularly suited to the more demanding high power applications where increased cut rate is important.

The range of coarse diamond abrasives are designed to be integrated into tooling solutions for professional users within the construction and stone processing industry as well as within consumer abrasive products for the DIY market.
The Element Six coarse diamond abrasive ranges have been developed for workpiece materials that range from the hardest granites, refractories and heavily reinforced concrete to softer marbles, limestones and lightweight building materials.
The extensive range of synthetic and natural diamond abrasives provide a complete range of solutions for all sawing and drilling operations. These include products for:
- Mono-blades
- Circular saws
- Frame saws
- Wire and beaded saws
- Multi-blades
- Drill bits
- Grinding applications
In order to aid selection of a particluar abrasive, Element Six has developed a colour - coded indicator system based on three sets of material parameters. In each product brochure the first indicator relates to the particle strength of each product at the three important temperatures.
The first value (on the blue scale) is the strength measured at room temperature, but it is well established that the strength of a diamond particle can be reduced when subjected to elevated temperatures, both during tool manufacture and at the cutting zone in application. Traditionally, this strength is measured after the diamond abrasive particle has been subject to a temperature of 1100°C in an inert atmosphere, and this forms the basis for the third value shown on the red scale. However, the effect of elevated temperature on diamond is a complex phenomenon. Factors such as exposure time, oxygen level and the presence of certain metals all contribute to this effect.
Consequently, Element Six offers a further strength indicator, particle strength at intermediate temperature, as shown on the green scale. This is the relative strength of the diamond after heat treatment at 900°C in an inert atmosphere.
For each of these temperatures, each product has been assigned a ranking, or Indicator Value, relative to other diamond abrasive particles within each series. The strongest materials have been assigned the highest strength indicator value, and the other products have been ranked in order below this. Since average particle strength increases as particle size decreases, Element Six has ensured that the relative ranking remains the same throughout the size range. As the values are only relative, the increments are not necessarily equal, but the indicator scale can be a valuable aid in assisting the toolmaker in selecting the correct product.
The second indictor gives a ranking based on the the proportion of crystalline particles within each product. A particle is described as crystalline if it has a regular defined shape, such as a cubo-octahedron, which is commonly associated with high strength diamond abrasive particles. A crystalline particle also has smooth faces and a sharp edge definition. These and other factors contribute towards the integrity of the particle and result in predictable breakdown characteristics in use.
Particles described as less crystalline are more irregular in shape, with rough faces and less well defined edges and are, therefore, different in their breakdown behaviour. However, such particles, by virtue of their irregular shape, are more free-cutting in appropriate applications, and have improved retention in the bond.
The Wear Mechanism Indicator (WMI), illustrates a particle's average wear behaviour under different operating conditions, and therefore differentiates between products both within and between Element Six abrasive particle series. The WMI is a simple representation of behaviour in use, showing schematically the wear progression of two actual working phases of the diamond particle under a range of operating conditions. The nature of this wear progression heavily influences the performance of the diamond tool, and is determined by a complex relationship between strength and structure.
Inappropriate diamond particle selection, or diamond particle selection based only on a single property such as particle strength, could result in the diamond particles displaying extended wear flatting behaviour (shown as a red area on the Indicator Chart), which in turn can give rise to an increase in power drawn, as a result of the dulling of the abrasive particle cutting points. Clearly the optimum situation is to select an abrasive particle product which achieves a balanced wear progression under the prevailing operating conditions. The WMI is invaluable in diamond particle selection where there is a choice to be made between products similar in strength, but differing in structure. In particular, the WMI is useful for predicting the free-cutting behaviour of a product.
