Shape (T): Triangular geometry with a  cutting angle, allowing for multiple usable edges.
Size (11): Represents the cutting edge length, which is approximately 11 mm.
Positive Rake: Usually features a clearance angle (often , denoted by 'C' in TCMT) that reduces cutting forces, making it ideal for fine finishing.
