Defense Industry
The idea of deep hole drilling emerged from its use for generating long and straight holes in the Guns and armaments industry. Defence industry is one of the major areas where deep hole drilling finds its application. The Barrel is the heart of the Gun and to obtain an accurate hole with the required surface finish is one of the precursors to a very accurate gunshot! Gun Barrel drilling is one of our specialties. Precihole has supplied numerous deep hole drilling solutions to most Ordnance factories in India for drilling and finishing various types of barrels like Piston barrel, Rifle Barrel, Shotgun Barrel etc. Precihole has developed specialty machines for operations like Rifling, Draw Boring, Pull Reaming, Honing and regularly services components like Torpedo tubes, actuator casing, breech block etc. for the defence industry.
