Professional Technical Features

Enhanced Rigid Structure: The Style B (8GR/9GR) body is significantly more robust than Style A, providing the necessary stiffness for deeper internal grooving and higher feed rates.
Comprehensive Radius Range: Includes both standard 0.20mm corner radius and specialized Full Radius profiles for specific engineering requirements.
Sharp Precision Grinding: Every cutting edge is precision ground to ensure absolute sharpness and dimensional consistency, resulting in mirror-like surface finishes.
Full L/R Hand Availability: All designations are available in Right-hand (GR) and Left-hand (GL) to accommodate diverse CNC machine configurations.
