Advantages of stainless steel turning tool CNMG120408-MS\MA
Stainless steel is a common processing material.
It has high strength and ductility, and is prone to sticky chips and built-up edges during cutting, which leads to faster tool wear and worse surface roughness. If you want to process stainless steel stably and efficiently, you must choose a blade designed specifically for it.
At this time, the CNMG120408-MS/MA stainless steel special turning blade just meets these processing problems.

What is CNMG120408-MS / CNMG120408-MA?
Let me first briefly introduce the model composition:
C: The blade shape is diamond-shaped, the tip angle is 80°, high strength and strong versatility
N: 0° back angle design, more stable cutting
M: Medium precision level, suitable for most common processing scenarios
G: Indicates with holes, double-sided grinding
120408: Indicates the size is 12mm side length, 4.76mm thickness, and 0.8mm tip radius
MS / MA: Indicates two different chip breaker types suitable for stainless steel:
MS: Medium load, smooth chip removal, suitable for continuous cutting
MA: Light load cutting, smaller cutting force, suitable for thinner or small parts processing

Key advantages of CNMG120408-MS/MA
1. Designed specifically for stainless steel to solve the problem of tool sticking
Stainless steel easily forms “built-up edge” on the blade, causing the blade to fail prematurely.
CNMG-MS/MA blades use a special chip breaker design to effectively control the shape of the chips, reduce chip sticking and built-up edge phenomena, and improve the quality of the processed surface.
2. Advanced coating, wear and heat resistance
We usually equip this type of blade with PVD TiAlN, TiCN or nano coating, which has excellent thermal stability and lubricity.
The blade tip remains sharp under high temperature conditions in stainless steel processing, extending the tool life.
3. Light cutting and reduced machine tool load
MS/MA chip breaker can effectively control cutting resistance, and the blade engages the tool gently, which is very suitable for medium-speed feed processing of CNC lathes, especially for processing austenitic stainless steels such as 304, 316, and 321.
4. Six tool tips are available, economical and practical
CNMG is a double-sided diamond blade. Each tool can use 6 tool tips (3 on each side), which has a longer service life and higher cost performance, especially suitable for batch processing companies.

So which materials is TNMG more suitable for?
Type | Insert structure | Number of cutting edges | Rear Angle | Applicable Materials | Features |
CNMG | diamond | 6 | 0° | Stainless steel, alloy steel, cast iron | High stability, suitable for rough and semi-finishing |
TNMG | triangle | 6 | 0° | Steel parts, quenched and tempered steel, ordinary structural steel | Suitable for light load and finishing scenes |
If you want to turn stainless steel and pursue smooth chip evacuation and stable cutting, then CNMG120408-MS/MA is obviously more suitable.
Why choose CNMG120408-MS/MA for stainless steel processing?
It can remove chips smoothly and reduce the problem of sticking
It cuts lightly and processes more steadily
It is durable and saves tool change costs
It comes from a professional factory with stable quality and fast delivery
Whether you are doing batch processing or pursuing surface accuracy, CNMG120408-MS/MA is your reliable choice for stainless steel processing!
