T Carbide Inserts, also known as Triangle 60° Inserts, are widely used in turning and facing operations. Their triangular design provides three cutting edges per insert, making them cost-effective and versatile.

The designation “T” refers to the shape code in ISO carbide insert standards, representing a triangular insert with a 60° included angle. These inserts are popular in general machining, offering an excellent balance of strength, accessibility, and economy.

⚙️ Applications of T (Triangle 60°) Inserts

T-style inserts are suitable for a wide range of CNC and manual machining applications, including:

• General Turning – Ideal for external and internal turning.

• Facing Operations – Produces smooth, flat surfaces.

• Light & Medium Machining – Effective for steels, stainless steels, and cast iron.

• Profiling – Triangular shape allows contour machining.

• Chamfering & Grooving – Can be used in multiple toolholders for different operations.

🔍 Types of T Carbide Inserts

T (Triangle 60°) inserts come in several variations depending on the geometry, edge prep, and application requirements:

1. TNMG Inserts – Negative rake, six cutting edges (most economical).

2. TPMR / TPMT Inserts – Positive rake, excellent for light cutting and finishing.

3. TCMT Inserts – Positive rake, sharp edge, best for stainless steel and aluminum.

4. TNMA / TNMM Inserts – Stronger inserts for heavy roughing.

5. Coated vs. Uncoated –

   • CVD-coated for steel and cast iron.

   • PVD-coated for stainless steel and finishing.

   • Uncoated for non-ferrous machining.
