h1. Carbide Grade
Select the proper insert grade from pages 114-115. Material type, machine capabilities and type of hole, i.e., Interrupted Cut, can affect the grade of carbide used.
h3. Coated
* Longer service life at higher speeds.
h3. Uncoated
* Less expensive and effective in materials for which coatings do notadd any benefit.
h3. Cermet
* Yields the highest speed and durability for selected materials.<br/><br/>
h1. Radius
Finish, bar rigidity, insert life, and engineering features of the workpiece all contribute to choosing the proper insert radius.
h3. Larger
* Better surface finish and longer insert life.
h3. Smaller
* Less cutting pressures, in extreme conditions, reduced bar flex and chatter.<br/><br/>
h1. Periphery
h3. Pressed
* Utility grade for general purpose. Longer tool life.
h3. Ground
* Better for finishing where tight bore tolerances are required.
