This 125mm diamond grinding wheel comes in 5 pieces of quarter round PCDs, and we enhanced it with 3 pieces of arrow type segments. Arrow segments are also can be used for coating removals. When it comes with PCD, the arrow segments can assist the PCD cup grinding wheel for more efficient coating removals. Quick Details Item Number SYF-P28125C Connection Type φ22.23mm Segment Details 3 pieces of arrow segments PCD Details 6 pieces of 1/4 round PCDs Application epoxy coating removal, glue removal, paint removal, etc Applied Machine angle grinder, floor grinder and etc. Packing Details 1pc/box Lead Time 7-15 days after order is confirmed. MOQ 10pcs PCD is sintered from diamond grits and a metal catalyst, under the condition of high temperature and high pressure. It has a sintered PCD top and a carbide substrate. The high wear resistance and high hardness make it an ideal material for cutting different objects. In concrete floor grinding tools, it is usually used for removing all kinds of floor coatings, including epoxy, glue, paint, resin, and others. Different from the copper welding of diamond segments, the welding type of PCD should be the silver welding. Because the silver welding needs a lower temperature (which could protect the sinter PCD split from the carbide substrate). SYF-P28100SYF-P28100BSYF-P28125ASYF-P28125C
