1. Why Choose Carbide Inserts?
Carbide inserts dominate modern machining because they combine toughness with hardness. Unlike traditional high-speed steel tools, carbide inserts provide:
High cutting speeds, enabling greater productivity.
Longer service life, even under elevated temperatures.
Reduced tool change time, since inserts can be quickly indexed.
Consistent surface quality, crucial for precision engineering.
Lower total cost, thanks to multiple usable cutting edges.
The TNMG-TSF/TM builds upon these advantages with chipbreaker designs tailored for different machining needs.
2. Decoding the TNMG-TSF/TM Designation
Each letter and suffix in the insert name has a technical meaning:
T – Triangular insert, offering 6 cutting edges.
N – Relief angle 0°, which strengthens the cutting edge.
M – Tolerance class “Medium,” suitable for general turning.
G – Insert with hole, double-sided, indexable.
TSF – Chipbreaker designed for light to medium finishing, ensuring excellent chip control and surface finish.
TM – Chipbreaker optimized for medium machining, balancing chip evacuation and edge stability.
By reading this designation, machinists can select the correct insert according to material and cutting conditions.
3. Specifications and Parameters
The TNMG-TSF/TM insert is manufactured under strict ISO and ANSI standards. Key technical parameters include:
Insert size (IC): 16 mm (typical, depending on variant)
Thickness: 4.76 mm
Hole diameter: 3.81 mm
Relief angle: 0°
Cutting edges: 6
Nose radius: Available in 0.4, 0.8, and 1.2 mm options
Grades available: Coated and uncoated carbide grades for steel, stainless steel, and cast iron
Coating types: CVD coatings (TiCN, Al₂O₃, TiN) for wear resistance; PVD coatings (TiAlN, TiCN) for high toughness applications
These specifications allow the TNMG-TSF/TM to adapt to varied cutting environments.
4. Application Fields
The TNMG-TSF/TM carbide insert is engineered for a wide range of turning applications. Typical usage scenarios include:
Automotive industry: shafts, gears, engine housings
General engineering: steel pipes, flanges, machine components
Energy sector: turbine components, large-diameter steel parts
Aerospace: precision parts requiring dimensional accuracy
Tool and mold making: semi-finishing and finishing tasks
TSF chipbreaker: Best suited for finishing steels and stainless steels, ensuring fine surface finish.
TM chipbreaker: Designed for medium cutting where chip evacuation and stability are equally important.
5. Distinct Advantages
The TNMG-TSF/TM offers several benefits that differentiate it from standard inserts:
Six usable cutting edges, reducing cost per component.
Triangular design, ensuring balanced cutting forces.
Tailored chipbreaker designs (TSF for finishing, TM for medium cutting).
Excellent wear resistance, supported by advanced coatings.
Stable edge strength, thanks to the 0° relief angle.
Wide material compatibility, covering steel, stainless steel, and cast iron.
These features make it a cost-effective yet high-performance solution.
6. Usage Guidelines and Precautions
For maximum performance, machinists should follow these best practices:
Select TSF geometry for finishing operations and TM geometry for medium cutting.
Adjust feed and speed based on workpiece hardness and toughness.
Use rigid clamping systems to minimize vibration.
Apply coolant when machining stainless steel to reduce heat buildup.
Rotate or replace the insert once flank wear exceeds recommended limits.
Following these recommendations ensures stable machining and extended tool life.

End mill for machining aluminum materials
Many customers have told us that ordinary end mills frequently stick when machining aluminum, and the accumulation of chips affects the accuracy, so they always change the tools. LIZHOU editor suggests that coated end mills are not recommended for aluminum materials, because some coatings contain aluminum elements. Therefore, it is better to choose uncoated end mills when selecting end mills for machining aluminum materials.
