Inserts Information

---

Shape

Square

• For rough boring through holes and castings to avoid exit hole breakout.
• Four usable edges for maximum insert life.

80° Diamond

• For rough boring to a shoulder or deep bore depths where maximum rigidity of the bar is required.
• For finishing small diameters where maximum edge strength is required.

Triangle

• For finishing with three corners for maximum insert life.

Trigon

• For rough boring when large depth of cut is required or when extreme core shift is experienced.
  
  
  

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.

Coated

• Longer service life at higher speeds.

Uncoated

• Less expensive and effective in materials for which coatings do not add any benefit.

Cermet

• Yields the highest speed and durability for selected materials.
  
  
  

Radius

Finish, bar rigidity, insert life, and engineering features of the workpiece all contribute to choosing the proper insert radius.

Larger

• Better surface finish and longer insert life.

Smaller

• Less cutting pressures, in extreme conditions, reduced bar flex and chatter.
  
  
  

Periphery

Pressed

• Utility grade for general purpose. Longer tool life.

Ground

• Better for finishing where tight bore tolerances are required.
  
  
  

Warning

The use of carbide in cutting is generally a safe and reasonable practice. When used properly, these products are designed to be safe and without risk to health and property. Please review the recommended use and pay particular attention to insure the tooling is used within its designed speed ranged and operating forces. Misuse may represent a hazard to people and property.

These products use materials which are classified as hazardous by OSHA. This may include one or more of the following carbide, titanium carbide, chromium carbide, chromium cadmium, cobalt, and nickel.

Carbide is a material which is brittle in nature. It will fracture from shock or impact which may cause pieces to detach at high velocities. Carbides should not be hammered or fitted with undo force. Suitable eye protection should be worn during all processes.

Carbide grinding may release dangerous levels of cobalt. Conventional precautions related to the operations of safe grinding should always be observed.

Additional information and material safety data sheets are available on request.
