ABSTRACT:
A rotary material removing tool has an elongated support whose rear end portion can receive torque from the motor of a boring or milling machine and whose front end portion has a front end face with a transverse recess for a carrier having in its front end face a transversely extending dovetailed guide groove for two elongated knife holders which are shiftable relative to each other and with reference to the carrier to select the distance between their knives. The support has two legs which flank the recess and bear against the carrier to hold the latter in abutment with the bottom surface in the recess and to deform elongated portions of the carrier into frictional engagement with adjacent portions of the two holders when the free ends of the legs are urged toward each other by a clamping screw. The holders can be shifted lengthwise of the guide groove in the carrier by discrete screws whose shanks mesh with the carrier and whose heads extend without axial play into notches of the respective holders and with axial play into notches of the carrier.
