Application :

1.Chipbreaker with special angle design can make cut easy, control chip and get good surface quality.

2.Special chip-breaker with high toughness cutting edge can reduce cutting force.

3.With stronger cutting edge, it is better for intermittent cutting than -DM,  with widely cutting  zone of  P type material

4.With sharp cutting edge, used for finishing machining inner hole, fine finishing surface can be got with 

a small feed rate.

5.With sharp wave cutting edge to reduce cutting force, it is the first choice for semi-finishing maching  of inner holes and can make chips flow smoothly.

6.With tough cutting edge, used for roughing/maching of inner hole of and intermittent maching 

work-piece with irregular surface.
