Diamond Tools

A diamond tool is made consisting of a support blade, a wire or drill tube, and a cutting edge with diamond-filled segments or beads. The segments or beads are made up of a diamond mixture and a bond, usually a metal powder, that is sintered together under high pressure and temperature. The quality of the diamonds and the concentration of diamonds in the segments determine the tool’s performance. The diamond tool cuts a deeper groove in the material being cut each time it is used. The diamonds on the surface of the segments progressively wear away, exposing fresh diamonds, at the same time that the connection wears away. As a result, it’s critical that the bond’s hardness is appropriate for the material to be cut.

Recipes and synthetic diamonds

The segments are made up of a blend of diamonds and metallic bond. To produce our diamond tools, we need diamonds of various sizes and properties. For the optimum performance, 4CoreBiz often uses industrial diamonds, which are high-quality synthetic diamonds that have been meticulously selected by our in-house expert team. The diamonds are combined with a bond made up of powdered metals. The specific recipe for the diamond and metal powder mixture is determined by the tool’s intended usage.


A diamond tool spins at a rapid rate. If the tool is not completely balanced, there will be a lot of vibration. The possibility of equipment damage and operator harm as a result of vibration is unacceptable. As a result, 4CoreBiz requires tool cores to meet the highest quality criteria. 4CoreBiz assures that the steel core is the finest in terms of geometry and steel quality as a professional supplier. Another issue might be excessive noise, particularly when using big wall saw or floor saw blades. 4CoreBiz can provide blades with a sandwich construction, in which the core blade is made up of three layers, as an alternative to solid cores. The two outer layers are composed of steel, and between them is a thin foil, usually made of copper, that lowers resonance in the core and so minimizes noise. When compared to a traditional blade core, the new design is thought to produce half the noise.


The segment and the connection between the segment and the core are subjected to high forces when a diamond tool is employed. The section can be flung out at a speed of up to 100 m/s if the joint cannot bear the stress (225 mph). It goes without saying that the quality of the junction between the segments and the core is critical. 4CoreBiz assembles the segments on the core using either silver soldering or laser welding. Laser welding is required for all sawing and drilling tools that do not require water cooling. Silver-soldered or welded tools for use with water cooling are available.
