Continental Industrial Diamond, Inc, (CID, Inc) was established in November of 1985. CID is located in the San Francisco bay area and services many companies worldwide. When Mr. Frank Lenner and Mr. Jorge Olmedo formed their partnership in 1985, they brought over 65 years of combined knowledge and skills to the design and manufacturing of CID tooling. That tradition continues today with Frank and Dee Lenner having acquired complete ownership of the company.
CID became a leader in diamond tooling and the manufacturing of mono-crystal, natural, CBN and PCD tools for various industries including contact lens tooling, automotive, aerospace and electric motor. CID was the first domestic manufacturer of diamond tooling to apply its own vacuum brazing oven for the benefit of its customers tooling needs. Our staff has continued to find improved methods of lapping diamond surfaces and has improved its manufacturing capabilities for PCD tooling with the purchase of EDM equipment.
While CID’s emphasis has been and will continue to be shaped diamond and CBN tooling (both shank and insert variety), we also manufacture diamond impregnated core drills starting at .026 for the machining of various products including glass, ceramics, quartz, fused silica and other crystal products.
