Claims20
A cutting insert comprising a main lip, a rake face and a coolant duct formed on a top side of the cutting insert, wherein the coolant duct runs at least partially in the rake face toward the main lip, and wherein the rake face has two chip breakers and two chip deflectors, and wherein the coolant duct extends between the two chip breakers and opens conically between the two chip deflectors.
A cutting insert comprising an insertion region for mounting the cutting insert in a cutting tool and a cutting region for machining a workpiece, a coolant duct located in the insertion region and extending along a central axis of the cutting insert, a pair of chip deflectors at one end of the insertion region proximate the cutting region, and a pair of chip breakers located in the cutting region that divides the coolant duct into a main coolant duct for directing coolant to a main lip and a pair of secondary coolant ducts for directing coolant to a pair of secondary lips formed at an angle of approximately 90 degrees with respect to the main lip, wherein the coolant duct opens conically between the chip deflectors.
