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
紐： Clearance Angle: Negative
中號： 公差：中等公差為標準，但也可能提供其他精度公差。
A: 斷屑槽樣式 & 孔配置。該字母表示特定的斷屑槽幾何形狀以及刀片是否有孔。斷屑槽種類繁多，且因製造商而異。
數字：
- 前兩位數字： 內切圓 (IC) 直徑（以毫米為單位）。要獲得近似的英吋當量，請將此數字除以 25.4。
- 接下來的兩位數字： 厚度以毫米為單位。除以 25.4 即可轉換為英吋。
- 最後兩位數字： 圓角半徑（以毫米為單位）。要轉換為英寸，請除以 25.4。
