drill bit length-diameter ratio - Purros Machinery

Length-diameter ratio is the ratio of the depth of the hole processed to the diameter of the drill bit. For example, the drill bit diameter is 12.7mm and the hole depth to be processed is 38.1mm, so its length-diameter ratio is 3:1. When the length-diameter ratio is about 4:1 or less, the chip grooves of most standard high speed steel bits can discharge the chip removed from the cutting edge of the bit more smoothly. When the length-diameter ratio

What Is Length-to-diameter Ratio (L/D)?

2018-6-25  L/D is the ratio of the length of magnetization direction of a magnet (L) to the diameter of the magnetization surface (D). For NdFeB magnets, L/D is of important reference significance for the preliminary judgment of the temperature resistance of the magnet. Under normal circumstances, we recommend an L/D of over 0.5 (preferably≥0.7).
