Which models of cnc bits can be used for mooz dobot?


Hello everybody,
Can anybody tell what kind of bits can be used for cnc module? I already overused the bit which comes with the machine, i need to order new ones and i guess there may be a variety of possible bits. I am attaching one of several works i did with default bit


First, ensure that the block can be fixed. Second, at the same time ensure that the range of cnc is not exceeded.
