Abstract
PURPOSE: To entirely prevent the inner wall of a machined bore from scratch, etc. by wear at the edge, chipping, growing scraps existing at the constituted edge in such a way that cutting is done with use of a constituted edge, and growing scraps existing at the constituted edge are gradually expelled outward through the third rake surface.
CONSTITUTION: Provision of the third rake surface 8 ensuing after the peripheral extremity of the first rake surface 6 at the part where the second rake surface 7 intersects with the peripheral side 9 facilitates to form a passage for growing scraps 11' existing at the constituted edge 11 which have arrived at the peripheral extremity by sideslipping over the first rake surface 6, the adhered direction is changed to main chips 12, and these growing scraps 11' are expelled out the same as the main chips 12. This serves for preventing the bored inner wall from scratching by impalement of growing scraps existing at the constituted edge 11, and for obtaining specular machining surface.
