An analytical model has been developed to investigate the drill wandering motion quantitatively. It has been shown mathematically why the resulting distorted polygon-shaped hole always has an odd number of sides during drill entry, and how the profile of the hole gradually becomes round with increasing hole depth. Drilling processes were simulated using this mathematical model and the results compared with experimental evidence. Subsequently, an experimental analysis on the influence of point geometry on drill wandering has been presented.
