Deep hole drilling is a specialist machining process used across multiple UK industries where accuracy, alignment, and internal bore quality are essential. At LDC Engineering Ltd, deep hole drilling is one of the core services offered in-house, with capacity up to 68mm in diameter to a depth of 2 metres. From toolmakers to the oil and gas sector, the need for deep, straight holes is common—and critical.
Whether it's a simple heater hole or a complex multi-level water circuit, LDC Engineering delivers consistent, high-quality results using proven tooling and a skilled team of engineers.
Supporting a Wide Range of Industries
The most common applications for deep hole drilling in the UK include mould tools, engine components, structural parts, and fluid transfer systems. In toolmaking, deep holes are required for precise temperature control. In automotive and aerospace, deep bores often house shafts, pins, or fluid channels. LDC’s ability to drill long and accurate holes into a variety of materials makes them a trusted partner across many sectors.
They machine an extensive range of materials, including duplex, stainless steel, mild steel, aluminium, copper, bronze, cast iron, cast steel, resin, nylon, and wood—all with the same focus on precision and repeatability.
Not Just Deep Hole Drilling – A Full Machining Partner
As well as their deep hole drilling services, LDC Engineering also provides gun drilling with capacity up to 38mm diameter to a depth of 4m, depending on the specification. This allows for the creation of smaller, high-precision bores with excellent internal finishes. For customers requiring more than drilling, LDC also offers CNC milling, turning, radial drilling, and surface grinding — all completed on-site in their West Yorkshire facility.
Their large surface grinder (1500mm x 500mm x 350mm) enables the finishing of sizeable components to fine tolerances, offering a complete machining solution under one roof.
