VCMT carbide inserts are one of the most widely used indexable turning inserts in CNC machining. Known for their versatility, sharp cutting edges, and high-precision finishing capabilities, VCMT inserts are ideal for both high-speed and general-purpose turning.

At CNC Tools Depot, the world’s largest marketplace for carbide inserts and cutting tools, you’ll find a comprehensive selection of VCMT inserts from leading global brands like Korloy, Kennametal, Widia, Taegutec, Mitsubishi, Sandvik, and more.

🔹 What Does VCMT Stand For?

Each letter in VCMT follows the ISO insert naming system:

• V – Insert Shape: 35° Diamond (Rhombic)

• C – Relief Angle: 7° clearance

• M – Tolerance Class: Medium precision

• T – Type: Single-sided insert with a hole

This geometry makes VCMT inserts perfect for applications requiring fine surface finish and detailed profiling.

🔹 Applications of VCMT Inserts

VCMT carbide inserts are widely used in:

• Finishing operations – delivering excellent surface finish.

• Semi-finishing turning – for precision machining of close tolerances.

• Profiling & contouring – sharp point allows machining of intricate shapes.

• External & internal turning – suitable for both OD and ID operations.

• Light cutting of steels, stainless steels, cast iron, and non-ferrous metals.

Industries using VCMT inserts include aerospace, automotive, medical devices, oil & gas, and general engineering.

🔹 Types of VCMT Inserts

Depending on the chip breaker, grade, and coating, VCMT inserts are available in different types:

1. Uncoated VCMT Inserts

   • Best for non-ferrous materials like aluminum and copper.

   • Provides sharp cutting edges and burr-free finishing.

2. CVD Coated VCMT Inserts

   • Durable coating for steel and cast iron machining.

   • Ideal for longer tool life in high-speed turning.

3. PVD Coated VCMT Inserts

   • Thin and sharp coating for stainless steel and superalloys.

   • Prevents built-up edge and enhances chip evacuation.

4. Finishing VCMT Inserts

   • With sharp chip breakers for smooth surfaces and accuracy.

5. Semi-finishing VCMT Inserts

   • Slightly stronger edge, suitable for moderate cutting depths.

6. Brands & Series Variations

   • Korloy VCMT160404, VCMT160408

   • Widia VCMT-PM Series

   • Kennametal VCMT-KC5010, KC5510

   • Taegutec VCMT-P Series
