For the bush hammer scratching roller, we have designed two different types: one is the carbide type, and the other is the PCD type. Here is the guide to choose the right scratching roller: 1. For scratching soft stones(such as marble), please choose carbide type. Why? Because the hardness of carbide teeth is not such high for scratching hard stones, but it is enough for scratching soft stones.  Besides, the carbide teeth are much more competitive compared with PCDs. 2. For scratching hard stones(such as granite), please choose the PCD type. Why? Because the PCD has a very strong hardness, wear-resistance, and it works well on the hard stones. It can also be used for soft stones. But in that case, it's not economical. Are you a trading company or a manufacturer of diamond tools?
