CoroTurn 107 For internal turning and external turning of slender components

CoroTurn® 107 is the first choice for external and internal machining of small, long, and slender components. Sharp cutting edges and excellent chip control ensure a soft cutting action and low cutting forces, providing an excellent surface finish to the component. Geometries designed for high-pressure coolant is also available.

 

 

 

Benefits

  • Improved chip control
  • Low cutting forces
  • Excellent edge strength

 

 

 

Features

  • 7º clearance angle
  • Screw clamping ensures stability and unobstructed chip flow
  • Insert geometries and grades for all materials
  • Wiper geometries available for high feeds and excellent surface finish
  • Holders and insert geometries with conventional and CoroTurn HP design

 


Application

Internal operations:

  • Long overhangs, 4-6 × D
  • Longitudinal turning and profiling
  • Boring holes, from Ø 6 mm

External operations:

  • Small and slender or thin-walled components
  • Longitudinal turning, facing, and profiling

 

The holders with high-precision nozzles improve chip control. The -PMC, -MMC, and -SMC insert geometries are designed to increase tool life in combination with these holders.
