About CNMG carbide insert

CNMG carbide inserts are 80-degree diamond-shaped, double-sided (negative) turning inserts designed for heavy-duty metal cutting, particularly in steel and cast iron. Featuring 4 or 8 cutting edges, they are prized for economic, high-productivity, and medium-to-roughing operations in CNC lathes, offering exceptional thermal stability and surface finish. [1, 2, 3, 4, 5]

Key Characteristics and Technical Specifications

Shape: 80-degree rhombus (diamond) shape allows for versatile turning and facing, often used in MCLNR/L, PCLNR/L, and MCLNR/L tool holders.
Design: Double-sided (negative rake) provides maximum strength, durability, and cost-effectiveness by offering 4 to 8 cutting edges before replacement.
Material & Coating: Generally produced from cemented carbide with coatings like CVD or PVD to enhance wear resistance.
Common Applications: Primarily used for external and internal turning, roughing, and semi-finishing of steel, stainless steel, and cast iron.
Chip Control: Usually features specialized chip-breaker geometry for efficient chip management. [1, 2, 3, 6]

Common ISO Designations

CNMG 120404/120408: The most common sizes, where 12mm is the cutting edge length, 4.76mm is the thickness, and 0.4/0.8mm is the corner radius.
CNMG 160612: Larger, heavier duty inserts (e.g., 16mm cutting edge). [7, 8, 9]
