Commissioning of a new Boehringer VDF B3 deep hole borer has delivered the additional capacity needed by the Bedfordshire-based contractor to satisfy the steadily growing demand for its specialist machining skills.
Hone-All is the specialist provider of deep hole boring services.

Deep hole boring is an extremely accurate process used to produce large, precision bores using specialist drill heads & indexable 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.
