Stainless steel is a common yet “ difficult ” material.

Due to its high toughness, high hardness, and poor thermal conductivity, many people often encounter problems such as tool sticking, built-up edge, and rapid tool wear when processing stainless steel. So, how to efficiently and easily turn stainless steel?

The answer is simple: choose a blade specifically optimized for stainless steel, such as TNMG1604-MA or TNMG1604-MS 。

With its excellent chip removal performance, wear resistance, and cost advantages, this blade has become the first choice for many customers.

What is TNMG1604 ？

Let's briefly understand the meaning of the model:

T ：Equilateral triangular blade, three corners

N ： 0° back rake angle, high rigidity

M ：Medium precision grade

G ：Double-sided blade, with hole design

1604 ：Side length 16mm ，Thickness 4.76mm ，Nose radius (depending on the model, there are 0.4/0.8/1.2 etc.)

If the suffix is MA/MS ，then it is a chip breaker specifically for stainless steel. It can not only easily cope with the problem of tool sticking in stainless steel, but also maintain good cutting performance at higher speeds.

TNMG1604 Four major advantages of processing stainless steel

Smooth chip breaking, say goodbye to tool sticking

The most troublesome problem in stainless steel processing is built-up edge and tool sticking 。 TNMG1604-MS/MA The blade uses a chip breaker designed specifically for stainless steel, which can effectively control the chip flow direction

Wear-resistant and heat-resistant, longer tool life

We use a high-toughness cemented carbide matrix, combined with nano-scale PVD coating (such as TiAlN or TiCN ), making the blade still sharp at high temperatures

Effectively prevent chipping, wear and oxidation 。Processing 304、316、321 stainless steel, the blade life is significantly longer.

3、 Light and fast cutting, small machine load

Thanks to MA/MS the optimized design of the chip breaker, the blade is light and fast, and the cutting resistance is small, effectively reducing the machine load and energy consumption 。It is particularly outstanding in continuous processing of CNC lathes.

Stainless steel TNMG and cast iron TNMG comparison

Many customers will ask: “ I used to use TNMG160404-HK to process cast iron, can I directly use it to machine stainless steel? ”

The answer is: Not recommended.

Comparison items	TNMG-HK (for cast iron)	TNMG-MS/MA (for stainless steel)
Material characteristics	High hardness, resistant to abrasive wear	High toughness, resistant to adhesive wear
Coating type	CVD (thick film)	PVD (thin film, heat-resistant and anti-adhesive)
Chip breaker design	Deep groove, suitable for chip breaking of brittle materials	Shallow curved groove, suitable for chip breaking of tough materials
Main advantages	Wear-resistant, suitable for high-speed dry	Non-stick, good heat dissipation, impact resistance
Typical processing materials	Gray cast iron, ductile iron	304、316、321、2205 Stainless steel
Interchangeability	❌ Not recommended	✅ More targeted

Summary: For cast iron TNMG Emphasis on wear resistance, facing brittle materials, while stainless steel is used TNMG More emphasis on anti-sticking, high temperature resistance and toughness.
