What is the difference between diamond segment and crushed PCD diamond segment?

If you are looking for a tool to remove epoxy, urethane, paints, glues and other coatings from concrete floors, you may have come across two types of diamond segments: regular diamond segments and crushed PCD diamond segments. What is the difference between them and which one should you choose for your project? In this blog post, we will explain the main features and benefits of each type of segment and help you make an informed decision.

Regular diamond segments are made of synthetic diamonds that are bonded together with metal powders. They are designed to grind and polish concrete surfaces with different levels of hardness and abrasiveness. Regular diamond segments have a smooth and continuous cutting edge that can achieve a high gloss finish on the floor. However, they are not very effective at removing thick and sticky coatings, such as epoxy, urethane, paints and glues. These coatings can clog up the diamond segments and reduce their cutting performance. Moreover, regular diamond segments can generate a lot of heat and friction, which can damage the concrete substrate and cause cracks or burns.

Crushed PCD diamond segments are made of polycrystalline diamonds (PCD) that are crushed into small pieces and embedded into metal matrix. PCD is a synthetic material that has a very high hardness and wear resistance. Crushed PCD diamond segments have a rough and irregular cutting edge that can create a scraping action on the floor. They are specially designed to remove thick and sticky coatings, such as epoxy, urethane, paints and glues. These coatings can be easily scraped off by the crushed PCD segments without clogging or overheating. Moreover, crushed PCD diamond segments can also expose the aggregate of the concrete and create a textured surface that can enhance the bond strength of the new coating.

So, which type of segment should you use for your project? The answer depends on the condition of your floor and the desired outcome. If your floor has a thin or soft coating that can be easily removed by grinding, you can use regular diamond segments to achieve a smooth and shiny finish. If your floor has a thick or hard coating that requires more aggressive removal, you can use crushed PCD diamond segments to create a rough and clean surface. You can also combine both types of segments in different stages of your project to achieve the best results. For example, you can use crushed PCD segments to remove the coating first, then switch to regular diamond segments to polish the floor.
