Lathe Cutting Tools

Lathe Cutting Tool Classification

Cutting tools are classified as

  • Single point cutting tools
    • Side Cutting Tool
    • End Cutting Tool
  • Multi-point cutting tools
  • Form tools.

1. Single point cutting tools

Single point cutting tools have one’ cutting edge which performs the cutting action. Most of the lathe cutting tools are single point cutting tools. Single point cutting tools used on lathes may be grouped into:

  1. Side Cutting Tool
  2. End Cutting Tool

Side cutting edge tools have their cutting edges formed on the side of the cutting tool, and are used on lathes for most of the operations. They are again classified as right hand tools and left hand tools. A right hand tool
operates from the tailstock end towards headstock and a

2. End Cutting Tools

End cutting tools have their cutting edge at the front end of the tools and are used on lathes for plunge cut operations.

2. Multi-point cutting tools

These tools have more than one cutting edge, and they remove metal from the work simultaneously by the action of all the cutting edges. The application of the multi-point cutting tools on the lathe is mostly done by holding the tool in the tailstock and feeding it to the work.

3. Form tools

These tools reproduce on the work the form and shape of the cutting edge to which they are ground. The form tools perform the operations on thework by a plunging action, and are fixed on the tool post square to the axis of the work and fed by a cross-slide. They may have their cutting
edges formed on square or rectangular section tool blanks acting radially. The form tools may be circular form tools and tangential form tools. They may require special holders to which they can be fixed, and the holders are clamped on the tool posts for operation.
