Deep hole boring is an extremely accurate process used to produce large, precision bores using specialist drill heads & index able tooling. This achieves close tolerances, excellent accuracy & good surface finishes. The petrochemical, hydraulic & aerospace industries are the largest customers for deep hole boring as they often require precision tubing in sizes & specifications that are unavailable to purchase from stock
