Twist Drill introduction Twist drill is the most widely used Drill Bit in industrial manufacturing, we generally use Twist Drill Bit length-diameter ratio when I art personnel for a specific hole processing task to select the most appropriate type of drill, the need to calculate the length-diameter ratio of the drill. The aspect ratio is the ratio of the depth of the hole being machined to the diameter of the bit. For example, if the bit diameter is 12.7mm and the hole depth to be machined is 38 1mm, the aspect ratio is 3:1. When the aspect ratio is about 4:1 or less, most standard twist bits will discharge the cuttings removed by the bit's cutting edge fairly smoothly from their grooves. When the aspect ratio exceeds the above range, a specially designed deep hole bit is required to achieve effective machining.
