MGMN carbide inserts are widely used grooving and parting-off inserts designed for precision machining in CNC turning operations. Known for their sharp cutting edges, excellent chip control, and high wear resistance, MGMN inserts are essential tools for industries requiring accurate groove cutting and cut-off operations.

At CNC Tools Depot, we provide a wide selection of MGMN inserts from trusted brands like Korloy, Widia, Kennametal, Taegutec, and more—ensuring consistent performance and long tool life.

What are MGMN Carbide Inserts?

MGMN inserts are double-ended grooving inserts primarily used in external grooving and parting applications. The “MGMN” designation typically refers to inserts designed for MGEHR/MGIVR type tool holders, making them highly versatile and widely compatible.

These inserts are commonly available in various widths such as:

• MGMN150 (1.5 mm)
• MGMN200 (2.0 mm)
• MGMN300 (3.0 mm)
• MGMN400 (4.0 mm)

Key Features of MGMN Inserts

1. Double-Sided Cutting Edges

Offers multiple usable edges, increasing tool life and reducing cost.

2. Excellent Chip Control

Special chipbreaker geometry ensures smooth chip evacuation.

3. High Precision Grooving

Delivers accurate groove widths and consistent results.

4. Strong Edge Strength

Designed to withstand cutting forces during parting operations.

5. Versatile Applications

Suitable for a wide range of materials and machining conditions.

Types of MGMN Carbide Inserts

MGMN inserts are available in different variations based on application:

1. Standard MGMN Inserts

General-purpose inserts for grooving and parting.

2. Coated MGMN Inserts

Feature coatings like TiN, TiAlN, or CVD for improved wear resistance and durability.

3. Uncoated MGMN Inserts

Best suited for aluminum and soft materials requiring sharp cutting edges.

4. Chipbreaker Variants

Different chipbreaker designs for:

• Finishing
• Medium cutting
• Roughing

5. Precision Ground Inserts

High-accuracy inserts for tight tolerance machining.

Applications of MGMN Inserts

MGMN inserts are widely used in CNC turning operations such as:

✔ External Grooving

Cutting precise grooves on outer diameters.

✔ Parting-Off Operations

Cutting off finished components from raw material.

✔ Internal Grooving (limited use)

With proper tool holders, can be used for internal grooves.

✔ Narrow Slot Cutting

Ideal for small-width groove machining.

✔ Mass Production

Highly efficient for repetitive CNC operations.
