TCMT Inserts are triangular carbide turning inserts with a positive rake angle, designed for both roughing and finishing operations. The ISO coding "TCMT" breaks down as follows:

• T = Triangle shape (60° included angle)

• C = Clearance angle (7°)

• M = Tolerance (medium, molded insert)

• T = Insert type (with hole, single-sided positive rake)

Unlike TCGT inserts (which are ground for higher precision), TCMT inserts are molded, making them more cost-effective and ideal for general-purpose turning.

⚙️ Applications of TCMT Inserts

TCMT carbide inserts are highly versatile and widely used in CNC turning:

• General Turning Operations – Suitable for steel, stainless steel, cast iron, and aluminum.

• Roughing & Semi-Finishing – Good balance of durability and cutting performance.

• Machining Non-Ferrous Metals – With polished/uncoated versions.

• Profiling & Contouring – Triangular shape allows multi-directional turning.

• Interrupted Cuts – Stronger edge makes them reliable in tough conditions.

🔍 Types of TCMT Inserts

TCMT inserts come in multiple variations to suit material and cutting needs:

1. Uncoated TCMT Inserts – Best for aluminum and soft materials.

2. PVD-Coated TCMT Inserts – Suitable for stainless steel and titanium.

3. CVD-Coated TCMT Inserts – Optimized for steel and cast iron.

4. Chipbreaker Variants – Available for finishing, medium, or roughing cuts.

5. Different Nose Radii –

   • 0.2–0.4mm → Precision finishing

   • 0.8–1.2mm → Heavy-duty turning

⭐ Advantages of TCMT Carbide Inserts
