DEEP HOLE DRILLING SERVICES
When standard drilling won’t go the distance, our deep hole drilling services deliver precision and depth with ease. Designed for applications where hole depth exceeds the diameter multiple times over, our specialist machinery ensures straight, accurate bores with clean finishes — even in the toughest materials.
We handle diameters from small to large, with depths extending well beyond conventional limits. From oil & gas components and hydraulic cylinders to aerospace and heavy industrial parts, our deep hole drilling solutions are trusted across sectors that demand tight tolerances, repeatability, and zero margin for error.
Using state-of-the-art equipment, skilled operators, and real-time monitoring, we offer consistent results whether it’s a one-off prototype or high-volume production run. Let us take on the jobs others can’t — and deliver them on time.
Where Deep Hole Drilling Makes a Difference:
-
Hydraulic Cylinders
Deep hole drilling is essential in the production of hydraulic cylinders, where long, straight bores are required for piston movement and fluid control. Precision is critical — any deviation in straightness can cause inefficiencies, leakage, or premature wear.
Our CNC-controlled process ensures optimal internal finish and alignment, making components reliable and ready for high-pressure use in heavy machinery and industrial equipment.
-
Oil & Gas Components
From drill collars to downhole tools, deep hole drilling plays a vital role in oil and gas equipment manufacturing. These components often require exceptionally deep bores through tough materials such as alloy steel or Inconel.
We’re equipped to deliver consistent internal diameters and surface finishes that meet industry standards, ensuring high durability and performance in extreme conditions.
-
Aerospace Parts
In the aerospace sector, weight reduction without sacrificing strength is key — and deep hole drilling helps achieve this balance. From landing gear shafts to engine components, we produce precision bores that reduce mass and improve functionality.
Our ability to hold tight tolerances over long distances makes us a trusted partner for aerospace manufacturers looking for exact, repeatable results.
-
Moulds & Tooling
Tooling and die manufacturers often rely on deep hole drilling to create internal cooling channels within moulds. These channels help maintain temperature control during production, improving cycle times and product quality.
We provide clean, accurately positioned bores that optimise thermal regulation, supporting everything from plastic injection moulding to die casting operations.
FAQs
-
Deep hole drilling is a specialised machining process used to create holes with depths significantly greater than their diameters — typically 10:1 or more. It ensures straightness, accuracy, and smooth internal finishes.
-
We can drill through a wide range of materials including carbon steel, stainless steel, aluminium, tool steel, and high-performance alloys such as Inconel and titanium.
-
We offer drilling services for diameters ranging from 3mm to over 50mm, with depths extending several hundred millimetres, depending on the material and application.
-
Our CNC deep hole drilling machines maintain tight tolerances and exceptional straightness — often within ±0.1mm over long distances, depending on the material and part geometry.
-
Industries like oil & gas, aerospace, hydraulic engineering, defence, and tooling commonly rely on deep hole drilling for precision parts and components.
-
We support both one-off prototypes and high-volume production runs. Every job is quoted based on complexity, material, and required turnaround.
-
Yes, we frequently drill internal bores and cooling channels for mould tools, dies, and heat-regulated components.
-
Deep hole drilling offers greater precision, better surface finish, and less tool deviation in high depth-to-diameter ratio holes — where standard drills would fail.
-
Absolutely. We accept DXF, DWG, PDF, and other formats, and can assist with design adjustments if needed to improve manufacturability.
-
Lead times vary by job size and complexity, but we offer fast, reliable turnaround — often within 2–5 working days for standard jobs.
“We needed precise deep hole drilling on a batch of hydraulic cylinder rods, and the results were flawless. The accuracy and surface finish exceeded our expectations — even across longer lengths. Turnaround was quick, and the team kept us updated from start to finish. Reliable, professional, and highly recommended.”
