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.

What types of end mills are there?
Materials can be processed according to different types of end mills, categorized by the types of milling tools, including flat end mills, ball end mills, radius end mills, chamfer end mills, and end mills with chip breakers.
2025-05-23
PCD milling cutter is a polycrystalline diamond (PCD) milling cutter, which has a wide range of applications in the field of machining.
2025-05-08
End mill for machining aluminum materials
Many customers have told us that ordinary end mills frequently stick when machining aluminum, and the accumulation of chips affects the accuracy, so they always change the tools. LIZHOU editor suggests that coated end mills are not recommended for aluminum materials, because some coatings contain aluminum elements. Therefore, it is better to choose uncoated end mills when selecting end mills for machining aluminum materials.
