Frequently Asked Questions (FAQs)
1. What is an indexable insert?
Indexable inserts Inserts are removable cutting tips, which means they are not brazed or welded to the tool body. They are usually indexable, meaning that they can be exchanged, and often also rotated or flipped, without disturbing the overall geometry of the tool (effective diameter, tool length offset, etc.).
2. What is a Cnmg insert?
The CNMG 322 Insert is a negative insert with chipbreaker that is recommended for Steel Finishing. Package of 10 CNMG 322 Carbide Turning Inserts. Negative Inserts with Chipbreaker. Recommended for Steel Finishing.
3. What makes a carbide insert indexable?
Indexable tools do have some drawbacks. Inserts are usually made by pressing carbide powder and binding materials into a die under high pressure. After forming, the inserts are heated to high temperatures and sintered, binding the powder and other materials together and giving the insert its strength.
