Indexable turning tool for chip forming machine

An indexible turning tool comprising a tool body including a securing portion and a holder projecting from the securing portion, the holder provided with pockets receiving respective replaceable cutting inserts, wherein each of the inserts has a main plane, the inserts all lying on an imaginary circle, wherein indexing of the tool body about an indexing axis brings the inserts into an operative cutting position, and wherein the main planes of the inserts do not all coincide with a single imaginary plane when the inserts are indexed into the operative cutting position.

An indexible turning tool comprising a tool body including a securing portion and a holder projecting from the securing portion, the holder provided with pockets receiving respective replaceable cutting inserts, the pockets arranged in a single ring about an indexing axis wherein indexing of the tool body about the indexing axis brings one of the inserts into an operative cutting position, wherein each of the inserts has a main plane, and wherein the main planes of the inserts do not all coincide with a single imaginary plane when the inserts are indexed into the operative cutting position.

An indexible turning tool comprising a tool body including a securing portion and a holder projecting from the securing portion, the holder provided with pockets receiving respective replaceable cutting inserts, the pockets arranged wherein indexing of the tool body about an indexing axis brings one of the inserts into an operative cutting position, wherein one of the inserts has a main plane oriented laterally relative to the indexing axis, each of the inserts having a plurality of corners including a radially outermost corner spaced radially farther from the indexing axis than the other corners of the insert, wherein a reference plane oriented perpendicularly to the indexing axis and passing through the radially outermost corner of the one insert is spaced axially from the radial outermost corner of at least one other insert,

• wherein the respective radial spacings of the inserts from the holder's center axis are substantially the same.
