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 ...

These tools, in either straight or ball end configuration, can produce intricate shapes in very hard steel (H>55Rc), quickly and without grinding. However to reach into small features, the length of the tool becomes large enough (length/diameter ratio >5/1) to influence the dimensional tolerances of the machined part due to deflection of the tool.
