Getting the most from the bit
Use a core rig suited to the bit diameter, keep the bit running at the recommended speed with steady feed pressure, and let the high-concentration segments cut instead of forcing the bit. Clear slurry as the manual directs and wear eye, hearing and respiratory protection. Follow the rig maker and MK Diamond safety guidance.
