D K Tools

Internal Turning Tools are specialized tools used in turning operations to machine the interior surfaces of a workpiece, such as bores, holes, or cavities. These tools are essential in precision machining, especially for components like cylinders, shafts, or other hollow parts. Internal turning is commonly performed on a lathe machine and involves removing material from the inside of a workpiece while it rotates.

1. Tool Geometry:

   • Cutting Edge: Internal turning tools have a sharp, tapered cutting edge that can reach deep inside a workpiece to cut or shape internal surfaces.
   • Toolholder: These tools are mounted on toolholders that allow the tool to extend inside the workpiece. The toolholder is designed to withstand the forces during cutting operations while ensuring rigidity and stability.
   • Insert Design: Many internal turning tools use indexable inserts, which can be replaced once worn out. These inserts are made from durable materials such as carbide, ceramic, or CBN (Cubic Boron Nitride), which provide the hardness needed for cutting tough materials.
