Insert with 25° corner angle for profiling

Y-Pro Series expands the machining range of taper cutting, undercutting, and “V” grooving applications

Applications & Features

Applications

External turningInternal turning

Features

1. Inserts with a 25° corner angle to expand machining possibilities

2. Suitable for a wide range of machining applications

The new Y-Pro series expands the machining range of Taper cutting, undercutting and “V” grooving applications.

Spherical profiling (Negative, Positive)

Enlarged clearance expands the interference avoidance area.

 

Face profiling (Positive)

Allows drastic productivity and capability improvements.

 

Internal undercutting and profiling (Positive)

Allows undercutting of small diameters.

“V” grooving (Negative, Positive)

Suitable for various “V” grooving applications.

 

External undercutting (Positive)

Allows a range of undercut forms to be machined.

 

Internal profiling (Positive)

Compared to the 35°positive insert, the 25° insert can work with smaller bore diameters.
