WALTER TOOLS 3/8" Inscribed Circle, CCGT, 80 Degrees Diamond, Carbide Turning Insert

What is the difference between a rhombic and a diamond-shaped turning insert?

• The rhombic insert features a square shape with 90-degree cutting angles & multiple cutting edges, whereas the diamond-shaped insert has a non-square, parallelogram-like shape with cutting angles that deviate from 90 degrees and fewer cutting edges.
• Rhombic inserts are versatile and commonly used for general turning, facing, and profiling, providing stability and balance. In contrast, diamond-shaped inserts excel in specialized applications, such as finishing, due to their non-90-degree cutting angles, which reduce forces and enhance surface quality.
• Rhombic inserts offer the advantage of multiple cutting cycles before indexing, while diamond-shaped inserts may require more frequent indexing or replacement.

How do I maintain these diamond carbide inserts?

Proper maintenance of these inserts involves regular inspection, cleaning and replacing inserts when they become worn or damaged.

What are the factors to consider while choosing the right turning insert?

Major factors include the material being machined, the desired outcome (roughing / finishing) and cutting conditions (speed, feed rate, depth of cut).
