The base and/or the cutting part are made at least in part of a fiber-reinforced plastic. In some embodiments, the fiber-reinforced plastic is CFRP or CFC. ## Claims ### Claim 1 A machining tool, comprising: a cutting part, a base body and plural cutting bodies, the base body made of fiber-reinforced material, the base body rotatable about a base body axis, the base body having a base body first end and a base body second end, the cutting part made of a fiber-reinforced material, the cutting part rotatable about a cutting part axis, the cutting part having a cutting part first end and a cutting part second end, the cutting part first end directly attached to the base body second end, the cutting part axis extending along the same line as the base body axis, the cutting bodies directly attached to the cutting part second end. ### Claim 2 (depends on 1) The machining tool according to claim 1, wherein the machining tool is a single-piece structure. ### Claim 3 (depends on 1) The machining tool according to claim 1, wherein the machining tool comprises multiple pieces. ### Claim 4 (depends on 1) The machining tool according to claim 1, wherein each cutting body comprises at least one of a steel material, a carbide material and a ceramic composite material. ### Claim 5 (depends on 1) The machining tool according to claim 1, wherein the cutting part first end is attached to the base body second end by at least one from the group consisting of a non-positive connection and a positive connection. ### Claim 6 (depends on 1) The machining tool according to claim 1, wherein the machining tool comprises an internal coolant and/or lubricant supply channel system. ### Claim 7 (depends on 1) The machining tool according to claim 1, wherein the cutting part comprises at least one material selected from among carbon fiber-reinforced plastic and carbon fiber-reinforced carbon. ### Claim 8 (depends on 1) The machining tool according to claim 1, wherein each cutting body comprises PCD or CBN. ### Claim 9 A machining tool comprising: a cutting part and a base body, the base body rotatable about a base body axis, the base body having a base body first end and a base body second end, the cutting part made of a fiber-reinforced material, the cutting part rotatable about a cutting part axis, the cutting part having a cutting part first end and a cutting part second end, the cutting part first end directly attached to the base body second end, the cutting part axis extending along the same line as the base body axis, the cutting part comprising plural cutting bodies. ### Claim 10 (depends on 9) The machining tool according to claim 9, wherein the cutting part is non-positively joined with the base body. ### Claim 11 (depends on 9) The machining tool according to claim 9, wherein the cutting part is positively joined with the base body. ### Claim 12 (depends on 1) The machining tool according to claim 1, wherein at least a portion of each cutting body is spaced farther from an axis of the machining tool than any portion of the cutting part is spaced from said axis. ### Claim 13 (depends on 9) The machining tool according to claim 9, wherein the machining tool is a single-piece structure. ### Claim 14 (depends on 9) The machining tool according to claim 9, wherein the cutting part comprises at least one material selected from among carbon-fiber reinforced plastic and carbon-fiber reinforced carbon. ### Claim 15 (depends on 9) The machining tool according to claim 9, wherein the base body comprises a fiber-reinforced material.
