    Frequently Asked Questions

    Which type of bush hammer scratching roller should I choose, Carbide or PCD?

    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.


    • 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.


    • 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?

    Yes, Quanzhou Sunny Superhard Tools Co., Ltd was established in 1993, and we are a professional and experienced diamond tools manufacturer in China.

    Sunny Superhard Tools uses high-quality materials and advanced production technology, as well as the strict inspection system to ensure the high & stable quality of our diamond tools.

    2. Much more competitive price.
    Our diamond tools are much more competitive than the trading companies. Because we sell our products directly to our customers, but the trading companies will take extra profit. What's more, for our agencies, we offer unexpected price to make win-win cooperation and establish a long term business relationship.

    For Sunny Superhard Tools, end-users of diamond tools are also very important. Because end-users can give us feedback about our diamond tools and this information is very important for us to improve our diamond tools in the future.
