At CNC Tools Depot, we bring you a wide selection of SCMT Carbide Inserts engineered for general turning, roughing, and finishing applications. Known for their square shape and negative rake design, SCMT inserts are highly durable, making them a top choice for medium to heavy machining in steels, stainless steels, cast iron, and non-ferrous alloys.

We stock SCMT inserts from trusted brands like Korloy, Kennametal, Widia, Taegutec, Mitsubishi, and more, ensuring machinists and manufacturers have access to the best tool performance and longevity.

🔹 What are SCMT Carbide Inserts?

The SCMT insert designation provides key information about its geometry:

• S = Square shape (90° cutting edge).

• C = Relief angle (7° clearance).

• M = Tolerance class (Medium, general-purpose).

• T = Insert type.

This makes SCMT inserts a balanced, all-purpose insert—ideal for machinists who need both strength and surface finish.

🔹 Applications of SCMT Inserts

SCMT carbide inserts are widely used in:

• General CNC turning and facing operations.

• Medium to heavy cutting applications where tool strength is critical.

• Roughing operations on steels and cast irons.

• Finishing cuts with high stability and strong edge support.

• Stainless steel machining with coated SCMT grades.

• Non-ferrous metal machining when polished edge SCMT variants are used.

🔹 Types of SCMT Carbide Inserts

At CNC Tools Depot, we stock multiple SCMT variations depending on material and machining style:

1. Uncoated SCMT Inserts

   • Sharp cutting edge, ideal for aluminum and non-ferrous metals.

2. Coated SCMT Inserts (CVD/PVD Coating)

   • Extended tool life in steels, cast iron, and stainless steel.

3. SCMT with Chipbreakers

   • For improved chip evacuation and stable cutting.

4. SCMT Steel-Specific Grades

   • Designed for toughness and resistance to edge chipping.

5. SCMT Universal Grades

   • One insert for multiple materials and applications.
