Specification

SNMA carbide inserts have 4 cutting edges per side. If the insert is negative then it is possible to use a total of 8 corners.

In this case, it makes this style of insert very economical.

It has a cutting edge angle of 90° so it has high cutting edge strength.

Normally, the insert dimension depends on the needs of customers and the space for the cutting tools in the application.

In addition, the Indexable Carbide Insert has gone through various processes such as quenching to improve its performance.

The surface has been treated with a special coating, thus it gains the properties of corrosion resistance and rustproof.

What’s more, it has the properties of good positioning accuracy, high hardness, long service life, wear resistance, corrosion resistance as well as cost effective.

The Indexable Carbide Insert is widely applied in metal turning, milling, cutting and grooving, thread turning, etc.

Understanding the SNMA Insert Code

S: Shape: Square
N: Clearance Angle: Negative
中号： 公差：中等公差为标准，但也可能提供其他精度公差。
A: 断屑槽样式 & 孔配置。该字母表示特定的断屑槽几何形状以及刀片是否有孔。断屑槽种类繁多，且因制造商而异。
数字：
- 前两位数字： 内切圆 (IC) 直径（以毫米为单位）。要获得近似的英寸当量，请将此数字除以 25.4。
- 接下来的两位数字： 厚度以毫米为单位。除以 25.4 即可转换为英寸。
- 最后两位数字： Corner radius in millimeters. To convert to inches, divide by 25.4.
