The company, established by Doctor Wei Zhang in 2002, is specialied in high-end manufacturing technology(in 2012, with the support of Changzhou Municipal Government, the fullly owned subsidiary Changzhou Jerry Cutting Tool Technolog INC. was established). The main products are gun drills for deep hole machining. The customers include famous engine manufacturers such as General Motors, FAW, Yuchai Machinery and Cummins.

    Gun drill is a difficult cutter in the CNC cutting industry, although its structure is not complicated. Its large length-diameter ratio and almost close loop machining make it difficult to release heat and evacuate chips. Therefore, it takes real expertise to make design and manufacture gun drills.
