Precision Gun Drilling Machines
When precision and depth matter, Kent CNC gun drilling machines deliver results that conventional drilling methods simply cannot achieve. Whether you’re manufacturing medical implants, high-performance fuel components, or aerospace parts, our machines are engineered to produce perfectly straight, burr-free holes at extreme depth-to-diameter ratios.
Why Choose Gun Drilling?
Unlike standard twist drills that struggle at depths beyond 10:1, the gun drilling process is specifically designed for deep, narrow holes. With a single cutting edge and internal coolant delivery, gun drills cut cleanly while flushing chips away, ensuring accuracy and tool life even at ratios as high as 400:1.
Key advantages of Kent USA gun drilling machines:
-
High precision at extreme depths
-
Superior chip evacuation with high-pressure coolant
-
Excellent surface finish and straightness
-
Proven productivity across industries
Applications Across Industries
Originally developed for firearm barrel manufacturing, gun drilling has become the standard in industries that demand reliability and accuracy:
-
Medical & Surgical Instruments – micro-diameter precision holes
-
Automotive & Diesel Components – fuel rails, injectors, precision shafts
-
Plastics & Molds – cooling channels in injection molds
-
Aerospace & Defense – lightweight, high-strength parts requiring deep bores
Gun Drilling vs. BTA Drilling
Selecting the right process depends on hole size and production goals:
-
Gun Drilling – Best for holes 1 – 50 mm (0.04 – 2.00 in), with coolant flowing through the tool and chips evacuated externally.
-
BTA Drilling – Ideal for larger diameters, with coolant entering around the tool and chips removed internally.
Kent USA provides both technologies to cover the full spectrum of deep hole drilling needs.
