1. Understanding the TNMX Turning Insert Designation
Each code in TNMX1106-2, TNMX1509-2, TNMX1508-L, TNMX1508-R follows ISO standards and provides essential information:
T – Insert shape: Triangle (60° corners)
N – Relief angle: 0° relief (straight cutting edge, strong and stable)
M – Tolerance class: Medium tolerance, balancing precision and cost
X – Special geometry or cutting edge modification for performance
Numbers (e.g., 1106, 1509, 1508) – Provide dimensions such as insert size, thickness, and corner radius
Suffixes (-2, -L, -R):
-2: Two cutting edges or geometry style
-L / -R: Indicates left-hand or right-hand cutting insert orientation
This coding ensures that machinists can easily match the correct insert to their toolholder and application.
2. Key Advantages of Carbide TNMX Inserts
As a carbide manufacturer, we engineer TNMX inserts with premium tungsten carbide substrate and advanced PVD/CVD coatings. The main advantages include:
High Hardness & Wear Resistance
With a hardness rating exceeding 90 HRA, the inserts can withstand abrasive wear during continuous cutting.
Superior Heat Resistance
Coatings such as TiN, TiCN, Al₂O₃, or TiAlN extend tool life by resisting high cutting temperatures.
Excellent Toughness
Designed to resist chipping and breakage, especially in interrupted cuts.
Stable Cutting Performance
The triangular design with multiple edges provides consistent surface finishes and dimensional accuracy.
Cost Efficiency
Multi-edge inserts reduce tooling costs by maximizing usable edges.
Versatility Across Materials
Effective in turning steel, stainless steel, cast iron, non-ferrous alloys, and heat-resistant superalloys.

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.
