Cutting tip holder and cutting tool

Abstract

This invention provides a cutting tool having a cutting insert holder which has a lighter weight and can be produced at a lower cost than that made of aluminum. The base of the cutting insert holder, to which at least one cutting insert is fixed, is made of an amorphous plastic including from 30% to 60% of glass fiber. The cutting insert holder has at least one female-screw member, such as a screw thread coil (e.g. a HELI-SERT® or Heli-Coil® insert), which has a screw tap for securing an adjusting member, to which a cutting insert has been fixed, to the base by screw-driving of a hexagon socket head cap bolt. The female-screw member is fixedly embedded in the inner end of an insert-holding recess formed in the base.
