Frequently Asked Questions (FAQs)

1. How do I choose a turning insert?

When choosing a turning insert, consider the application demands and the space available for the cutting tool. A larger insert size provides better stability, which is suitable for heavy machining. For finishing, the size can often be reduced.

2. What are the different types of inserts?

There are several types of turning inserts available: 1. Square insert: has 4 cutting edges per side. 2. Triangular insert: has 3 cutting edges per side. 3. 80° Rhombic insert: used for external machining and facing. 4. 55° Rhombic insert. 5. 35° Rhombic insert. 6. Trigon insert. 7. Round insert.

3. How many types of inserts are there?

There are four main types of four-sided inserts: diamond, square, rectangular, and rhombic. Diamond inserts have two acute angles and are used for material removal. Square inserts have four equal sides. Rectangular inserts have four sides, with two longer sides. Rhombic inserts come in different angles, such as 80°, 55°, and 35°.
