Gun drills are the most accurate, fast and capable type of drills that manage to cut deep holes on metal materials through a controlled release of highly compressed fluids. Those drills are the only ones that can bore holes of depth to diameter ratios of about 350.
These rods have a hole on their front hardened tip from which the fluid flows at high enough speeds to cut strong materials with remarkable accuracy. The chips that are produced by the cutting process are removed through the use of coolants that also flow inside the bored hole. This also helps keep the drilling temperatures at a lower than melting level.
Features
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.
There is no other type of drill that can compete with the astonishing cutting rates achieved by gun drills. At high speed modes, quality gun drills can bore steel metals at a rate of 75 cm per minute or more. This is combined with unparalleled cutting accuracy that produces cuts of perfect surface finishing that normally won't need any hand polishing in most cases.
Applications
Gun Barrels Making
The most common application of gun drilling machines is for boring gun barrels. This is exactly where those tools got their name from after all. All gun barrels feature the high depth to diameter ratios that only gun drills can realize.
Gun drilling machines are ideal for the particular application as the perfect finishing of the inner surface of the gun barrel ensures the unobstructed and unaffected trajectory of projectiles. Moreover, the accuracy of the cuts ensures coherent barrel thickness which subsequently means homogeneous heating and thus less cracks and longer lifetimes.
Molds and Dies
Another application that calls for the unique abilities of the gun drilling machines is the manufacturing of molds that are used for the production of heavy duty metal parts or large tools. The gun drill can help bore a deep hole through which the molten alloys can be inserted into the casting area.
Tool Manufacturing
Hardened tools made out of chromium and vanadium steel can only be successfully processed by high precision tools among which are gun drills. These are ideal for boring deep holes that can be used for the fitting of extensions and adapters. Usually, these are done in a polygonal shape to increase the torque friction.
Making Musical Instruments
Last, gun drilling machines are extensively used in the music instrument manufacturing industry and especially for wind instruments that require deep holes of small diameter. These instruments can be flutes, oboes, bassoons, saxophones, clarinets, trumpets, ocarinas and reeds. As most of these instruments are made out of brass and other soft metals, gun drill machines are required to work with precision and delicacy as the slightest deformation will result in wrong tonal performance.
