Patent ID: 7220086

Claim:
A tool head for employment in machine tools with a base body ( 12 ), a tool shank ( 14 ) projecting axially beyond the base body ( 12 ) and adapted for being coupled to a rotating machine spindle, and at least two plate receptacles ( 18 , 18 ′, 18 ″) spaced apart in the circumferential direction for receiving respectively one indexable cutting plate ( 20 , 20 ′, 20 ″), such that a main cutting edge in a cutting position exhibits differing adjustment angles (α, α′, α″) relative to the base body axis, wherein identical indexable cutting plates ( 20 , 20 ′, 20 ″) are provided in the different plate receptacles ( 18 , 18 ′, 18 ″), wherein the active main cutting edges ( 34 ) of the indexable cutting plates ( 20 , 20 ′, 20 ″) are subdivided along their length into at least two cutting segments ( 36 , 36 ′, 36 ″) in alignment with each other, wherein for each of the various plate receptacles ( 18 , 18 ′, 18 ″) respectively only one of the cutting segments ( 36 , 36 ′, 36 ″) of the indexable cutting plates is effective with the associated adjustment angle (α, α′, α″), wherein the indexable cutting plates are provided with an imprint in the area of the main cutting edge marking the individual cutting segments, and wherein each imprinted cutting segment in the area of the main cutting edge of the indexable cutting plates is associated with one of the plate receptacles.
