Abstract:
A chip removing cutting tool comprising a holder and an insert removably secured in said holder,said insert including front and rear ends, said front end containing a cutting edge, said rear end including a rear face, upper and lower surfaces of said insert being of generally V-shaped cross-section and extending along a front-to-rear direction, said V-shape being bisected by a longitudinal midplane of said insert, said holder including: a forwardly opening slot formed by upper and lower front-to-rear extending walls of V-shaped cross-section, each wall defined by mutually angled planar wall sections, said walls facing one another and engaging said upper and lower surfaces, respectively, and being elastically flexed apart thereby, to frictionally grip said upper and lower surfaces, respectively; at least one of said upper and lower surfaces being provided with first and second recess patterns extending thereinto and situated on respective sides of the longitudinal midplane, said first and second recess patterns being spaced from one another, each recess pattern comprising recesses spaced apart in said front-to-rear direction, wherein adjacent pairs of said recesses define non-recessed portions therebetween, said non-recessed portions being spaced apart along said front-to-rear direction each of said recesses having a width in said front-to-rear direction in a range of substantially 0.002 to substantially 0.02 inches, and said adjacent recesses being spaced apart by a distance in a range of substantially 0.01 to substantially 0.05 inches; said planar wall sections of said holder slot functionally engaging said non-recessed portions and extending across said recess patterns.
