Description
Product Overview
The MGMN400-M grooving insert is a precision‑engineered carbide tool designed for demanding internal grooving applications. Manufactured by FomaSP, a leader with over 15 years of experience in carbide technology, each insert features a high‑performance gray PVD coating that dramatically improves resistance to both abrasive and adhesive wear. This coating not only extends the service life of the insert but also maintains a consistently sharp cutting edge, reducing the frequency of tool changes and downtime. The insert dimensions—width 0.157″ (4 mm), radius 0.0157″ (0.4 mm), length 0.827″ (21 mm), and overall diameter 0.13″ (3.3 mm)—are optimized for the Korloy grooving holder, ensuring a secure fit and stable cutting performance. The package includes ten pieces, providing ample inventory for continuous production runs and allowing users to maintain a stocked supply of high‑quality inserts.
In addition to its robust construction, the MGMN400-M insert offers excellent thermal shock resistance, making it suitable for intermittent cutting cycles where rapid temperature fluctuations are common. Its high toughness and impact resistance enable it to handle the dynamic forces encountered during grooving of medium‑hard alloys, delivering smooth chip flow and minimizing the risk of chip adhesion on the cutting edge. The insert’s geometry is specifically tailored to reduce friction between the workpiece and the tool, resulting in lower cutting forces and improved surface finish on the machined groove.
Usage
The MGMN400-M inserts are ideally suited for a wide range of industrial machining scenarios, including aerospace component fabrication, automotive part production, and general manufacturing where internal grooves are required. They perform exceptionally well in machining stainless steel, titanium alloys, and other medium‑hard materials that demand precise groove dimensions and a high-quality surface finish. The inserts are compatible with the MGEHR/L and MGIVR/L grooving tool holders, making them a versatile choice for machines equipped with these standard holders. Users can expect reliable performance in both high‑speed production environments and smaller batch operations, thanks to the insert’s ability to maintain cutting efficiency over extended periods.
When used in intermittent cutting applications, the insert’s superior thermal shock resistance helps prevent cracking or deformation caused by rapid temperature changes. This makes the MGMN400-M an excellent option for operations that involve frequent start‑stop cycles or variable cutting speeds. The PVD coating also reduces the tendency for chip welding, which can otherwise lead to tool wear and poor surface quality. By selecting the MGMN400-M insert, manufacturers can achieve consistent groove dimensions, reduce post‑machining finishing work, and improve overall productivity.

FAQ
What materials can the MGMN400-M insert machine effectively?
The insert is designed for medium‑hard alloys such as stainless steel, titanium, and similar materials where precise internal grooves are required. Its PVD coating and carbide composition provide the necessary hardness and wear resistance for these applications.
How does the PVD coating improve performance?
The gray PVD coating creates a hard, low‑friction surface that resists both abrasive wear from the workpiece and adhesive wear from chip buildup. This results in a longer service life, fewer tool changes, and more consistent cutting performance.
Can the inserts be used in high‑speed machining?
Yes, the MGMN400-M inserts are suitable for high‑speed operations. Their geometry and coating are engineered to maintain stability and edge integrity even at elevated cutting speeds, delivering clean grooves with minimal surface defects.
What is the recommended replacement interval?
Replacement intervals depend on the specific material being machined and the cutting conditions. However, the enhanced wear resistance of the PVD coating typically allows for significantly longer intervals compared to standard carbide inserts.
Is there technical assistance available for setup?
FomaSP provides comprehensive technical support, including setup guidelines, optimal machining parameters, and troubleshooting assistance to ensure you achieve the best results with the MGMN400-M inserts.
