|DSB 5-3||25||Soft||Large grit with soft bond delivers aggressive performance and high productivity - well suited to hard floors and use on low-powered grinders.|
|DSB 7-4||30/40||Medium||A highly versatile ‘general purpose’ diamond segment. Good for removing trowel marks and finish suitable for paint coatings. Best performance (longer life) on harder concrete.|
|DSB 7-5||80||Medium||Productivity and wear characteristics similar to DSB 7-4 but finer grit means they are suitable for early stage floor polishing.|
|DSB 7-6||120||Medium||Similar to DSB 7-5 but with still finer grit for next stage cutting/polishing. For polishing, it would be suggested to follow with 120 grit resin button or pad.|
|DSB 8-4||30/40||Hard||Same grit size as DSB 7-4, but the harder bond makes them more suitable for softer or more abrasive concretes. This is a long-life segment, which means production rates will be lower in most circumstances.|
|DSB 9-4||30/40||Very hard||Same grit size as the DSB 7-4 and DSB 8-4, but encased in our hardest bond material. Once again, this is a slow-wearing, long-life combination recommended for very abrasive and recently-laid concretes.|
|PCD is the recognised abbreviation for Polycrystalline Diamond. This diamond material has different characteristics to that used in the metal-bonded diamond products listed above. In particular, PCD plates are sharper and more durable.|
|PCD Grit||High||Hard||Grit particles in this segments can be irregularly shaped, 5-8 mm across a face and presenting very sharp cutting edges, They are commonly used for removing thick or pliable coatings, including latex and glue residues.|
Unlike PCD Grit, where the diamond is embedded in a rectangular segment bock, PCD Plates usually comprise a single, large piece of the polycrystalline diamond adjacent to a strip of solid PCD material; both are fitted on the standard-style bolt, coatings and pliable materials.
PCD plates are directional, constructed to be used for either clockwise or anti-clockwise rotation - use them in the wrong direction and they will be probably be destroyed in seconds. This warning is most applicable when using diamond grinders powered from a three-phase supply!
