TNMG carbide insert

About TNMG carbide insert

TNMG carbide inserts are triangular-shaped, negative-rake cutting tools with 60-degree corners, widely used for external and internal CNC turning. Designed with six cutting edges (three on each side) and a central clamping hole, they are ideal for high-productivity roughing to finishing on steel, stainless steel, and cast iron. [1, 2, 3, 4]

Key Characteristics

• Shape: Triangular (60 angle).
• Rake Angle: Negative (0 relief), offering high edge strength for heavy cutting.
• Edges: Double-sided, typically providing six usable cutting edges.
• Application: Excellent for external and internal turning, facing, and profiling.
• Material: Carbide with CVD/PVD coatings for wear and heat resistance. [1, 2, 3, 5]

Common ISO Designation Components (e.g., TNMG 160408)

• T: Triangular shape.
• N: 0 relief angle (negative).
• M: Tolerance class.
• G: Feature code (usually chipbreaker + hole).
• 1604 (Size): Cutting edge length (16mm) and thickness (4.76mm).
• 08 (Radius): Nose radius, e.g., 0.8 mm. [2, 5, 6]

Common Applications

• TNMG 160404/331: Used for finishing and semi-finishing.
• TNMG 160408/332: Commonly used for general turning and light roughing.
• TNMG 160412/443: Used for heavy roughing and high-removal applications. [5, 7, 8, 9]

These inserts are highly favored for their durability and economic value in high-volume production, offering high wear resistance and a specialized chip breaker for better chip control. [1, 2, 10, 11]
