Features

Double-Sided Cutting Edges: SNMG inserts offer multiple cutting edges on both sides, increasing their cost-effectiveness.

Chipbreakers: SNMG inserts often come with various chipbreaker geometries designed to improve chip control and surface finish in different materials and machining operations.

Coatings: Inserts are frequently coated with materials like TiN, TiCN, and Al2O3 for better wear resistance, heat tolerance, and optimal performance in different materials.

Typical Applications of SNMG Inserts.

SNMG insert Meaning

S: Square shape with a 90-degree included angle. This shape provides strength and stability to the cutting edge.

N: Negative rake angle. This refers to the angle at which the cutting edge meets the workpiece. A negative rake angle creates a stronger cutting edge, suitable for heavier cuts and harder materials.

M: Medium tolerance class. This indicates a general-purpose range of precision, making these inserts suitable for various machining applications.

G: Ground finish. This means the insert’s surfaces have been ground for accuracy and dimensional consistency.

SNMG inserts are versatile and used in various turning applications, including:

Roughing: Their strong cutting edge and negative rake angle make them suited for heavy material removal.

Semi-Finishing: They can provide a decent balance between strength and surface finish for semi-finishing operations.

General-purpose Turning: Their versatility makes them a popular choice for general machining of various materials.

SNMG inserts come in various sizes, corner radii, and other specifications. The most common variations include:

SNMG 1204 and SNMG 1906 are among the most widely used sizes.
12 or 19: Indicates an Inscribed Circle (IC) of 12mm or 19mm (approximate). The IC determines the overall size of the insert.
04, 06, 08, 12: Indicates the thickness (e.g., 0.157″ or 4mm for 04)
02, 04, 08: Indicates the corner radius (e.g., 0.031″ or 0.8 mm for 04). Larger radii provide a stronger cutting edge, while smaller radii offer a better surface finish.
