GUN DRILLING SERVICES :-

What is Gun Drilling?

Gundrilling is a deep hole drilling process. The gun drilling process is able to drill deep holes beyond what is possible with conventional machinery and tooling such as twist drills, by using high-pressure coolant for clean chip exhaust, even at extreme depths.

It is the ideal process for a range of deep hole drilled depths and diameters. Extremely deep holes and small diameter holes utilize gun drilling with specific equipment to maintain straightness and precision. A gun drill tool differs from a conventional twist drill by its unique head geometry; a standard gun drill has a single effective cutting edge that removes chips as it advances into a metal workpiece.

What do we provide?

We are able to drill deep holes beyond what is possible with conventional machinery and tooling such as twist drills, by using high-pressure coolant for clean chip exhaust, even at extreme depths.

We guarantee to provide exceptional quality with a focus on our customers’ economic drivers, resulting in cost savings and shorter lead times. We are committed to providing the highest level of service and on-time delivery.

Gun Drilling can be done in hole sizes from 0.060 in. dia. to 2.25 in. dia. in all materials and shapes. Standard and exotic materials can be handled. Capabilities include prototyping, CNC machining, large run production, honing, OD turning and grinding. Industries served to include aerospace, defence, mould and die, medical, oil, gas and power generation. Gun drilling materials from aluminium to zirconium including ceramics can be drilled and many more.

All the Machining Centres are equipped to gun drill holes from 3m/m dia to 20m/m dia in all materials including Inconel & Titanium.
