business man of diamond tools 800-800Hi Miley- yes we didi test them this weekend. The concrete we were grinding this weekend was super hard and the diamond segments held up pretty good. We had to add more weights to our machine mostly do to the large surface on the segments that’s why we went to the new ones you guys just shipped out.I will leave a good review on your website.Thank you.

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.

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.

2. Much more competitive price.
