How do I choose between carbide and diamond rock saw?
In most cases, unfortunately, there isn’t a plain straight forward answer to this question. There is a broad selection guide presented in the Products section. While it is safe to say that carbide saws are unsuitable for materials above 40 MPa and diamond saws are unsuitable for compressive strengths below 15 MPa, it is the region in between, which is encountered the most, where it is the hardest to decide. In most cases the really decisive factors are external considerations as * the availability of water – carbide does not have to have water available, for diamond it is a must * noise and vibration level – carbide tipped rock saws are noisy while diamond is smooth and relatively silent * the value of the cut product – if you are selling the stuff you cut, then remember that about 10% of your product gets wasted on width of cut when carbide rock saw is used. This become less than 2% for diamnod tipped rock saw * labour and fuel costs and the value you place on productivity – in terms
