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.
