It is very important to choose the correct cutting tool slot type when turning thread. Groove shape can affect chip control, tool wear, thread quality, and tool life.

1. Plane slot

 Generic, for most materials

ER cutting tool to ensure tool strength


2. Sharp grooves

 For viscous or work hardening materials such as mild steel, stainless steel, non-ferrous materials and superalloys

 Sharp cutting edges ensure low cutting tool force and good surface quality


3. Chip breaker type

 Suitable for long chip materials, such as low carbon materials. It can also be used for stainless steel, alloy steel and non-ferrous metal materials

 More continuous chip forming groove with no machining

 Do not use it with radial feed
