CUTTING TOOL FOR WORKING END GROOVES Russian patent published in 2007 - IPC B23B29/34 

FIELD: working metals by cutting, rotary cutting tools for high-speed working.

SUBSTANCE: cutting tool includes housing with stem, cutting heads mounted in guiding surfaces of housing, inserts with cutting tips mounted in guiding surfaces of heads and moved by means of adjustment screw. Said guiding surfaces of housing and of heads are formed with possibility of sensing centrifugal efforts occurring at rotation of cutting tool. In order to simplify axial adjustment and to enlarge range of radial regulation of position of cutting tip, guiding surfaces of heads are arranged on housing in parallel to axis of cutting tool and guiding surfaces of inserts are in the form of riffles arranged normally relative to axis of cutting tool. Surface of insert opposite to said riffles is convex one and it is designed for engaging with elastic wall of head at securing insert in head.

EFFECT: simplified axial adjustment of cutting tip, enlarged range of radial regulation of position of cutting tip.
