    Great company to deal with nominal customer service. I had a slight problem give up with a great solution. I definitely will be buying more from this company and I would suggest anybody who needs a diamond bits purchased from this company.

    The bit they had recommended worked out exceptionally well. Much better than I anticipated. They really know what you’re talking about. A bit that I purchased did exactly what it was supposed to do in record time it’s always a pleasure to deal with people who are well experienced, and what they saw.
