Gun drilling is the ideal process for drilling small diameter holes without losing straightness and precision. It creates close tolerance holes in high-temperature alloys and a range of steels. Machines must be configured to precise specifications, then operated using precision tooling, high-pressure coolant, and an interrupted feed. Some applications require a sub-micron finish that a gun drill can’t achieve, so extra processes and customisation are often needed such as honing.
Gundrilling is a specialised art, so there can be a lot of confusion about basic variables such as time, cost, and quality. This can create a headache for buyers, especially as clients – who arrive from a variety of demanding sectors, such as aerospace, defence, and automotive – need to know that the finished product will meet their specifications with absolute precision. Let’s take a look at gundrilling timings.
You may think that they all say that, and they probably do.

It’s the only way for us, and it has delighted thousands of customers throughout the years. We believe we have the winning formula of professionalism, advanced technology and industry expertise and it’s all at your disposal.
The process of gundrilling was initially developed to create uniform sized holes in artillery pieces and rifles. Techniques and technologies were set in place to give repeatable, highly accurate results on mass armament production lines, from the late 19th century onwards. Gundrilling is still used in the defence industry, but has far wider applications too.
When carried out using the right equipment and with the right training, gundrilling delivers reliable results each time. This is the reason the technique – which you may also know as deep hole drilling – is so widely used in manufacturing. Hundreds of aerospace, automotive and medical components, among others, use gun drilling to produce precision holes of almost any length.
Gundrilling (alternatively called Deep Hole Drilling) is a reliable method used to make precision holes in a wide range of metal and plastic components. The method is known for its efficiency in creating perfectly round drilled holes and straight drill channels. However, sometimes mistakes are made with gundrilling that affects the final accuracy of the result.
If so, you’re certainly not alone.
Drilling, honing and boring costs are notorious for being something of an arcane secret for people who aren’t ‘in the know’ about the process involved. We have attempted to shed some light on the world of pricing in our latest downloadable e-book: The Guide To Deep Hole Drilling, Boring & Honing Costs. You can download a copy by clicking here.
Gundrilling refers to a process of drilling deep, precise holes in many different materials, from super alloys to aluminium. The key elements to deep hole drilling methods are tight diameter control, good finish, and straightness.
A deep hole is defined by the depth-to-diameter ratio and every hole larger than a ratio of 10:1 is considered deep. There are lots of applications for deep hole drilling across many industries, with the origins tracing back to gun barrels. Deep hole drilling is used in different materials and can help achieve a tight diameter, straightness, and a perfect surface finish.
