Peck drilling is characterized by its method of progressing in incremental steps. This technique involves drilling a hole in multiple passes, or "pecks," which allows for better control of depth and reduces the chance of tool breakage or overheating. By retracting the drill bit between these pecks, you can clear out chips and debris, ensuring a smoother process and a more accurate hole.

Unlike rapid drilling methods which typically seek to achieve depth in a single pass, or high-speed methods that prioritize cutting speed without necessarily accounting for gradual depth control, peck drilling is specifically designed to enhance precision and manage the drilling operation effectively. The focus on incrementally advancing the drill allows for adjustments in feed rate and depth, which is especially useful in harder materials or when precise dimensions are critical. This method is also not aimed at creating very shallow holes, as it is more about reaching deeper depths through controlled, stepwise increments rather than merely drilling at superficial levels.
