Deep Hole Drilling - Gun Drill
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

Support For High Speed Grinding
