Over the past 16 years Premier Deep Hole Drilling has processed a wide range of components have been processed for offshore drilling and exploration companies including wellheads, manifolds and, increasingly, components used for data monitoring and flow measurement purposes in drill head assemblies.

"Like all our work, highly concentric deep holes finished to micron finishes are commonplace on these components, " Mr Grant comments. "But in reality, oil and gas work is not treated by us any differently to any other components being processed for, say, our customers in the aerospace, motor sport, medical and hydraulics sectors."<$>Every component is produced exactly to drawing, and the care and attention it receives does not change whether the holes are 3000mm deep, are ground to one micron tolerances or honed to<0.1 micron Ra. "'It is all about providing the customer with exactly what is required, when required - and this has been a driving factor in our investment in valueadded machining services."<$>Premier Deep Hole Drilling maintains 26 gun drilling machines for holes from 2.5mm diameter by 3000mm deep; three ejector drilling machines for holes up to 75mm diameter by 1500mm deep; 13 honing machines for honing bores from 2.5mm to 150mm diameter; plus a wide range of CNC turning (up to sixaxis) and milling (four-axis) machines complemented by surface and cylindrical grinding technology.
