IDI diamond coated tools have top cutting performance and the longest tool life. With specially sintered substrate, high performance tool geometry and excellent diamond coating, IDI tool’s life time can exceed 12-20 times that of uncoated ones. A Zoller Measuring Machine, a Mitutoyo Laser Scan Meter and other precise equipment are used for tool geometry, diameter and run out control. All tools willbe 100% checked under a microscope to make sure every tool you get is perfect !
Tool life depends on machine tool, tool holder, graphite hardness and surface quality requirement…, etc.
The above data may not fit all cases.
