Abstract
A cutting tool for severing a non-metallic material includes a holding element and a cutting element held on the holding element for cutting contact with the non-metallic material. A boundary region adjoins a holding material region of the holding element and a cutting material region of the cutting element. The precise severing of, for example, bone materials of human or animal origin, is possible in that a deformation resistance against an elastic deformation of the holding material region is greater than a deformation resistance against an elastic deformation of the cutting material region.
Claims14
A cutting tool for severing a nonmetallic material, the cutting tool comprising:
- a holding element;
- a cutting element held on said holding element, said cutting element being configured for cutting contact with the non-metallic material;
- and
- a boundary region adjoining a holding material region of said holding element and a cutting material region of said cutting element, said holding material region having a deformation resistance to an elastic deformation greater than a deformation resistance to an elastic deformation of said cutting material region;
- and
- said holding material region consisting of a holding material and said cutting material region consisting of a cutting material, said cutting material being different from said holding material, and said cutting material being steel;
- a modulus of elasticity of said holding material is greater than a modulus of elasticity of said cutting material, and said holding material having a material matrix with a matrix ductility and wherein hard material particles are disposed in said material matrix with a particle ductility which is less than the matrix ductility.
