Gun drills are basically straight fluted rods that use highly pressurized fluids to achieve cutting into great depth in metal materials. The depth to diameter ratios that can be realized by those specialized tools ranges from 250 to 500.
Around this fluted rod that is essentially the drill, circulates the coolant that keeps drilling temperatures below melting point for both the drill and the workpiece while the chips that are produced from the process flow outside the drilled hole.

The most important part of a gun drill is its tip, as this is the point that is called to sustain the tremendous pressure of the effused fluids. For this reason, the tips are made out of hardened metal alloys and aerospace-grade composite materials. This prolongs their service life and ensures that no catastrophic deformations will take place.
The speed of gun drill machines is one of the strongest characteristics of this tool as high speed drills can bore steel at a rate of 75 cm per minute or even more depending on the diameter. The most significant advantage of deep hole drilling machines, though, is the extreme accuracy with which they can cut through hardened metals. These tools can achieve an astonishing finishing that rarely needs further polishing.
Ways Gun Drilling Tools Can Be Applied
Boring Gun Barrels
The most obvious use scenario for the gun drilling machines is for the drilling of gun barrels, which is where this specialized tool got its name from. Gun drills are ideal for the boring of such long holes into rigid metal materials.
The accurate cutting of gun drills makes it possible for very intricate metalwork and produces a smooth finishing on the inner side of the barrel that rarely even needs any polishing at all. This is especially important for guns as bullets that travel at very high speeds could have their trajectory affected by even the slightest deviation.
Molds and Dies
Another case of gun drilling machine application is for the manufacturing of molds that are suitable for the production of metal parts or tools. In this case, gun drills are especially useful as the molten material may have to be inserted through a relatively long hole and into the casting mold.
Tool Making
Some special purposed tools such as the extension fitters found in every toolbox wouldn't be producible without the help of gun drill machines. As these tools are usually made out of chromium and vanadium steel alloys, it is very hard to drill holes in them at high levels of precision. Gun drilling can even achieve polygonal features for torque keys etc.
Musical Instruments
Last, there is the musical instrument industry that requires high precision machinery to achieve certain tonal results out of wind instruments. These can be flutes, clarinets, oboes, saxophones, ocarinas, reeds, bassoons and trumpets, as they all include deep holes of great finishing. Although the soft materials that wind instruments are usually made out of don't require the sheer cutting power of other applications, the cutting precision required can only be met by gun drill machines.
