At CNC Tools Depot, we bring you the largest collection of DCMT Carbide Inserts, designed for precision, performance, and durability in CNC machining. Known for their 55° diamond-shaped geometry, DCMT inserts are widely used for turning, profiling, and finishing applications on steels, stainless steels, cast iron, and non-ferrous materials.

Whether you are using Korloy, Kennametal, Widia, Taegutec, Mitsubishi, Sandvik, or Iscar tooling systems, we have the right DCMT insert to fit your machining needs.

What are DCMT Carbide Inserts?

• Shape: Diamond-shaped insert with 55° angle

• Relief Angle (C): 7° clearance, ensuring smooth cutting

• Tolerance (M): Medium tolerance for balanced accuracy

• Chipbreaker & Grades: Available in multiple geometries and coatings (CVD/PVD) for roughing to finishing operations

This makes DCMT inserts one of the most versatile and widely used insert types in CNC lathes and turning centers.

Applications of DCMT Carbide Inserts

DCMT inserts are engineered for precision turning operations, delivering excellent surface finishes and long tool life. Key applications include:

• External Turning – Ideal for finishing and semi-finishing operations

• Profiling – Perfect for contouring and complex geometries

• Copy Turning – Smooth surface generation on curved surfaces

• Grooving & Chamfering – Suitable for light grooving, facing, and chamfer applications

• Material Versatility – Works efficiently on steels, stainless steels, cast iron, aluminum, titanium, and exotic alloys

Types of DCMT Inserts (Based on Chipbreaker & Grade)

1. DCMT with Finishing Chipbreaker (F) – Delivers high precision & smooth surface finishes

2. DCMT with Medium Chipbreaker (M) – Best for general turning & profiling

3. DCMT with Roughing Chipbreaker (R) – Handles higher cutting forces & material removal

4. Coated DCMT Inserts (CVD/PVD) – Enhanced tool life, wear resistance, and heat protection

5. Uncoated DCMT Inserts – Preferred for soft materials like aluminum and non-ferrous metals

Advantages of Using DCMT Carbide Inserts

• High dimensional accuracy with 55° diamond geometry

• Excellent chip evacuation with specialized chipbreakers

• Longer tool life due to advanced carbide grades & coatings

• Compatible with multiple tool holders & brands

• Versatility – supports finishing, semi-finishing, and profiling in one insert type
