Diamax diamond tools undergo rigorous testing both in the field and in the laboratory. In 2007 we became one of the first diamond tooling companies to begin contracting with an independent testing laboratory to test our tools against the competition. Tests are conducted by Environ Laboratories in Minneapolis, MN, an ISO/IEC 17025 accredited industrial testing laboratory in a strictly controlled environment. Here are the results of our ongoing testing of our core bits.
Core bits were spun at 3500 RPM and then orbited at about 60 rpm in a 5 degree orbit. The total amount of downward pressure on the bits was 40lbs. The granite used was 3cm Absolute Black. Bits were purchased by the testing facility and shipped directly to them from several different tool distributors.
