Precision Gun Drilling for Demanding Applications
Gundrilling is a deep hole drilling process that uses a long, thin cutting tool to produce holes in metal at high depth-to-diameter ratios. Gundrilling is effective in diameters from 1 – 50 mm [0.04 – 2.00 in]. Our Gundrilling machine can perform jobs of min diameter 3mm, max diameter 30mm with a length up to 1500mm. ( Number of machines- 2).

FAQ about Gundrilling Services
The primary difference lies in the diameter range and the way coolant is delivered. Gun Drilling is the superior choice for smaller, high-precision holes, typically ranging from 3mm to 30mm in diameter. In this process, high-pressure coolant is pumped through the center of the tool and chips are exhausted through a V-shaped flute on the outside. BTA Drilling, however, is designed for larger diameters (usually above 20mm) where chips are evacuated through the center of the drill tube. At Accurate Edge, we recommend Gun Drilling for applications like fuel injectors, medical instruments, and aerospace pins where exceptional straightness and a mirror-like surface finish are non-negotiable.
Our specialized gun drilling equipment is capable of achieving an incredible depth-to-diameter ratio, reaching depths of up to 1500mm (1.5 meters) in a single pass. What sets gun drilling apart from conventional twist drilling is the “burnishing” effect of the tool’s guide pads, which support the drill bit against the hole wall as it advances. This self-piloting action ensures that even at extreme depths, the hole remains remarkably straight with minimal drift. This capability is essential for the UAE’s oil and gas sector, particularly for manufacturing long-reach hydraulic manifolds and specialized downhole sensors.
Gun drilling is renowned for producing a “finished” hole in a single operation, often eliminating the need for secondary reaming or honing. We typically achieve a surface finish (Ra) as low as 0.4 to 0.8 µm, which is ideal for high-pressure sealing surfaces. In terms of dimensional accuracy, we can maintain diameter tolerances within ±0.01mm to ±0.03mm, depending on the material. Whether you are working with stainless steel, titanium, or high-strength alloy steels, our process ensures a burr-free, highly round hole that meets the stringent requirements of the aerospace and defense industries in the UAE.
