[QUOTE="CreviceSucker, post: 574636, member: 1804"] Are you saying your diamond matrix was glazed or polished ? can you post a photo ? Look up the Cerchar abrasive index numbers for the quartz you are drilling. There is data available online for most areas if you look. Its not just hardness thats a problem for cutting tools , as mentioned above , the abrasiveness is a big factor and it varies massively and the diamond bond should be designed to suit that rock , if you have enough water then i would expect the bond is too hard. An example for you is a rock saw i designed was getting around 5 years life from wear pads in Sydney sandstone , when it was put onto a job cutting pure quartz reef 600 - 1000 mm thick , the wear plates were smashed within 3 months. 5 years versus 3 months is a service life wear factor of 20 times difference.
