Advantages of WNMG080404-MS for machining stainless steel
Stainless steel, a material we see every day, is actually not easy to deal with during processing.
It has strong ductility, high toughness, and poor heat conduction, and is particularly prone to problems such as built-up edge, sticking, and increased wear.
If the wrong insert is selected, processing will not only be difficult, but the tool life will also be greatly reduced.
So, how to process stainless steel efficiently and stably? The answer is – WNMG080404-MS stainless steel special turning insert.
What is WNMG080404-MS?
Let’s quickly understand the meaning of the model:
W: Hexagonal insert, 80° cutting edge, high rigidity
N: 0° back angle, suitable for heavy-duty cutting
M: Medium precision grade
G: With hole, double-sided
080404: side length 8mm, thickness 4.76mm, corner radius 0.4mm
MS: Stainless steel chip breaker, medium load, smooth chip cutting, optimized for sticky materials
In short, WNMG080404-MS is a high-performance turning insert designed specifically for 316 steel materials.
Comparison with WNMG-HK inserts for cast iron
Many customers will ask: “I used WNMG080404-HK to process cast iron before, can I use it directly to process 304 steel?”
The answer is: not recommended. The original intentions of the two designs are completely different.
Comparison items WNMG080404-HK (cast iron) WNMG080404-MS (stainless steel)
| Material properties | High hardness, anti-abrasive wear | High toughness, resistant to adhesion and wear |
| Chipbreaker design | Deep groove, suitable for chip breaking of brittle materials | Shallow bend, suitable for chip breaking of tough materials |
| Key Benefits | Wear-resistant, not easy to chip | Non-stick knife, smooth chip cutting, anti-built-up edge |
| Processing characteristics | Dry high speed, interrupted cutting | Medium to high speed, continuous or interrupted cutting |
| Typical Materials | Gray cast iron, ductile iron | 304, 316, 321, duplex stainless steel |
Conclusion: Cast iron blades emphasize wear resistance and chipping resistance, while stainless steel blades emphasize anti-sticking, heat dissipation and toughness. Using the wrong blade will not only reduce efficiency, but also damage the tool.
So what material is WNMG more suitable for?
Although WNMG is also a model familiar to many customers, there are obvious differences between it and WNMG in application.
| Type | Insert structure | Number of available cutting edges | Rear Angle | Applicable Materials | Features |
| TNMG | triangle | 6个 | 0° | Ordinary steel, alloy steel, structural steel | Average rigidity, suitable for light load or continuous cutting |
| WNMG | Hexagon | 6个 | 0° | Stainless steel, cast iron, alloy steel | High rigidity, suitable for heavy load and interrupted cutting |
Simply put: If you often encounter intermittent working conditions, thick-walled parts or pursue tool life in machining, WNMG is better.
