Z-LION arrow cup diamond grinding wheel for hand-held grinders for concrete grinding. The special features of the tool are as follows:
• High-quality diamond is used in the matrix to make the tool with good cutting/grinding capacity.
• Diamond segments are hot-pressed and professionally welded onto the metal base. The density of segments is reasonable and the balance of the tool is good so extend the lifetime of the tool.
• Diamond segments can be changed to other shapes like rectangles, rhombi, T shape, S shape, L shape, etc. The number of segments can be increased or reduced depending on a specific application. Cup wheels with fewer segments offer faster, more aggressive grinding; while cup wheels with more segments provide smoother finishing and longer life.
• Metal base comes with big holes to reduce the total weight of the cup wheel, provide more efficient dust collection, and cool down segments during work.
• Every cup wheel has to pass our balance testing, so the tools are in good balance, work smoothly and wear reasonably.
• Work with hand-held grinders, and cover small areas that floor grinders can not reach.
