Deep hole drilling is a machining process that can produce holes up to ten times deeper than the diameter of the hole and is suitable for a variety of metals, including the strongest of superalloys. Deep hole drilling services require special tools and setups to deliver high-pressure coolant, cleanly evacuate chips and reach the depth-to-diameter. Deep hole drilling, also known as gun drilling, is a highly-specialised machining operation that only a few engineering companies can perform, including PRV Engineering. Here is a closer look at some of the processes, applications and pros and cons.

Deep hole drilling (DHD) – or deep hole machining (DHM) – is a residual stress measurement technique often referred to as gun drilling. It’s a prominent method in engineering materials and components used across numerous sectors, including automotive and vehicle construction, aerospace and renewable energy. Deep hole drilling is also used in die and mould making and hydraulics or pneumatic components.
Today, there’s a growing demand to put gun drilling into a multi-tasking format, just as you would with common machining techniques such as milling, turning and gear-cutting on one platform. With deep hole machining being a multi-task platform you can create opportunities to offer an incredibly high-quality finished product.

Deep hole drilling, often referred to as gun-drilling, is a highly-specialised machining operation that only a select few engineering companies can perform. This method is used when high-precision round bores are vital to the operation. It produces holes that can be controlled within very tight tolerances, giving much greater accuracy compared to conventional drilling methods.

Deep hole drilling (DHD) is a stress measurement technique used in engineering materials and components to measure locked-in and applied stresses. The process measures residual stresses at a microscopic level with penetration of over 750 millimeters (30 in), without destroying the original component.
Advances in engineering technology have given common CNC machining centres gun drilling ability up to a certain depth-diameter ratio. Roundness and surface finish are among considerations. Common applications of deep hole drilling and machining processes include
