Spotting Drill is suitable for positioning and chamfering. Before the formal boring, it is necessary to pre-drill a centering hole on the workpiece with the positioning drill. The centering hole is for drilling position of the secondary drill bit, which is beneficial for subsequent drilling processing. Drill is suitable for deep bore machining. High Speed Indexable Drill (U drill) is an inner-cooled drill bit with good chip release and high efficiency; it could drill continuously. Reamers are used for reaming and hole repair. The hole that have been drill (or reamed) on the reaming workpieces are generally rough. Reamer mainly purpose is to improve the machining accuracy and smooth treatment. Due to small amount of cutting, the reamer requires a higher machining accuracy than the drill.
