An adjustable multiple blade boring bar with diametrically disposed overlapping blade blocks, each adjustable in and out and a control cartridge having actuator pins movable in opposite directions in response to rotation of a differential screw, the pins being oriented in relation to slots on the blade block to move in a camming relationship to shift the blocks in and out. A differential screw associates the control cartridge and the boring bar to permit radial equalization of the blade block when installed initially or after sharpening.
