Drilling is one of the most common methods of metal removal. Less than 70 years ago, if someone was talking about deephole drilling it automatically meant he was talking about gundrilling, simply because there didn't exist any other processes at the time. Nowadays though, the mechanical engineer is in the fortunate position of having more processes to choose from when faced with the problem of deephole drilling. There are three commonly used techniques that are available:
1. Gundrilling 2. STS/BTA system 3. Ejector system

Gun drilling is a precision deep hole drilling process that uses a long, straight tool to produce extremely deep holes in a variety of materials. This tool has a unique head geometry, and a groove along the length of the tool, differentiating it from a conventional twist drill.
The main uses are:fine processing of all kinds of metal mold cavity, such as shoe mold etc.the carvings of various metal and non metal processes, and the carving of the craft gifts.clean up the flown, burrs and welds of the cast, forged and welded parts, such as the machine casting plant, the shipya
For deep hole drilling, several kind of drills appeared in the history, flat drills, half-round drills, twist drills, gun drills etc. Only gun drills are popular for special features of single cutting edge with self-guiding, automatic chips-removal and cooling lubrication.
Deep hole drilling is beneficial across several applications. Oil and gas exploration equipment, armaments, aerospace equipment, and engines are common applications for deep hole drilling and machining processes. In each of these industries, hole qualities are necessary for high-performance end products, such as landing gear that easily retracts. Production requires deep hole drilling that is reliable, accurate, and time-efficient.
