Features and usage of diamond pastes / compounds

Diamond pastes & compounds have better cooling and lubracting features compared to standard grinding compounds and pastes. Thanks to this fact, diamond pastes & compounds allows increase the lapping / polishing speed by 2-5 times and thus increase quality of the machined surface.

We recommend using diamond paste for lapping and polishing of tools and parts from tungsten carbide, technical ceramics, quartz and other very hard materials.

Diamond pastes & compounds are used in engineering industry for finishing operations on e.g. industrial tools, sintering molds, pressing molds, nozzles, drawing swages, etc. They are used for machining parts with very high tolerances, like parts of hydraulic and fuel systems, pressing molds for plastics, or for polishing of stone and gemstones.
