VNMG-MA\MS stainless steel turning insert

Understanding the Code: VNMG160404-MA/MS

The insert code follows ISO 1832 standards. Each letter and number conveys specific technical details:

V – Insert shape: Rhombic 35° diamond shape, ideal for precision finishing and profiling in narrow areas.

N – Clearance angle: 0° relief (neutral). Provides maximum edge strength and tool stability.

M – Tolerance class: Medium tolerance, suitable for general machining with high dimensional accuracy.

G – Insert type: Double-sided, with hole and chipbreaker for secure clamping.

16 – Inscribed circle (IC): 16 mm, the key reference size of the insert.

04 – Insert thickness: 4.76 mm, balancing strength and edge sharpness.

04 – Corner radius: 0.4 mm, providing smooth finishing capabilities.

MA / MS – Chipbreaker and geometry code:

MA: Multi-application geometry, optimized for stable chip control and smooth surface finish in finishing to medium cutting.

MS: Sharp cutting geometry designed for stainless steel and low cutting force applications, improving productivity in difficult-to-machine materials.

Advantages of VNMG160404-MA/MS Carbide Inserts

Outstanding Precision

The 35° diamond shape allows fine profiling, threading, and finishing in tight spaces.

Suitable for parts requiring high dimensional accuracy and smooth finishes.

Versatile Cutting Capability

MA geometry supports general steel, alloy steel, and cast iron turning.

MS geometry excels in stainless steel and heat-resistant alloys, where chip control and low cutting forces are critical.

High Tool Life

Advanced PVD and CVD coatings (TiN, TiAlN, Al2O3) improve wear resistance.

Premium fine-grain carbide substrate ensures edge toughness and prevents chipping.

Chip Control Efficiency

Special chipbreaker design reduces chip accumulation, avoids re-cutting, and maintains consistent performance.

Especially effective in continuous and semi-interrupted turning.

Cost Efficiency

Double-sided insert provides four cutting edges per insert, lowering tooling cost per part.
