The present invention provides a cutting insert pocket in a cutting insert holder for securely retaining a cutting insert. The cutting insert pocket is provided with a base and two angularly disposed insert support sidewalls transverse to the base. A first of the two insert support sidewalls being fixed relative to the base and having two coplanar spaced apart insert location surfaces, a second of the two insert support sidewalls being rotatable about an axis transverse to the base and having two coplanar spaced apart insert location surfaces. This arrangement enables four-point location of the cutting insert in the cutting insert pocket, instead of the usual prior art three-point location. |
