Boring heads and systems are suitable for production operations such as CNC machining centers. MD boring bars provide an adjustable bar in a rigid setup when used in end-mill holders or collet holders. Precise adjustments are said to be easily made while the bar is in the machine or in the tool block of a presetter.
