TANGENTIAL CUTTING TIP AND HOLDER FOR IT Russian patent published in 2007 - IPC B23B27/00 B23B27/16 

FIELD: working metals by cutting, built-up tools for radial and axial turning of rectangular steps.

SUBSTANCE: in order to enlarge manufacturing possibilities due to non-limited length of working in axial and radial directions tip has two descended angles and two raised angles. Descended angles are formed nearer to mean plane of tip. Holder has seat for tip where supporting plate and cutting tip are mounted. Said seat is restricted by basic surface for engaging with main lateral surface of cutting tip, first lateral wall protruded from basic surface for engaging with additional lateral surface of cutting tip and second lateral wall protruded from basic surface. Supporting plate has upper surface for engaging with non-working end surface of cutting tip, opposite lower surface for engaging with second lateral wall of seat. Screw for fastening supporting plate in seat passes in its through opening and it engages with threaded opening in second lateral wall. Locking screw for fastening cutting tip in seat passes in its through opening and it engages with threaded opening in basic surface of seat.

EFFECT: enlarged manufacturing possibilities due to non-limited length of working in radial and axial directions.
