Premium 1.25" Grooving & Parting System | KGER-1.25 with 10 MGMN400 Inserts
The Perfect Balance of Strength and Precision for Demanding Production
Bridge the gap between heavy-duty and extreme-duty cutting. The MGMN400 insert on the robust 1.25-inch shank delivers an unbeatable combination of exceptional edge security, excellent surface finish, and high metal removal rates. It’s the intelligent choice for high-performance shops that won’t compromise on reliability or quality.
This Complete High-Performance Kit Includes:
1 x KGER-1.25 Performance Blade Holder
Shank Height: 1.25 Inches (31.75mm) – Provides the rock-solid foundation needed for stable, high-feed cuts.
Tool Style: KGER (Right-Hand).
Build: Precision-engineered from high-tensile steel with a reinforced clamping system to handle the significant cutting forces of the MGMN400 insert.
10 x MGMN400 Carbide Inserts (Double-Sided)
Specification: MGMN400 (4mm inscribed circle) – The Optimal Mid-Range Powerhouse.
The Strategic Advantage: Offers 33% more edge strength than the MGMN300, with a more compact format than the MGMN500 for excellent accessibility and chip flow. Ideal for deep grooving and aggressive parting where both strength and precision are critical.
Edges: 2 cutting edges per insert = 20 high-performance cutting edges.
Grade: Typically supplied in a premium, multi-layer coated grade (e.g., AlTiN or TiAlN-based) optimized for high-speed machining of steels and cast irons.
Why the MGMN400 Kit is the Smart Choice for Advanced Shops:
⚖️ The Ideal Compromise: Maximizes strength and depth-of-cut capability without the bulk of the MGMN500, making it more versatile for a wider range of groove widths and machine powers.
⚖️ Superior Chip Control: The insert geometry is engineered for efficient chip formation at high feed rates, preventing bird-nesting and ensuring safe, uninterrupted production cycles.
⚖️ Enhanced Process Security: The combination of the ultra-stable 1.25" shank and the robust MGMN400 insert dramatically reduces the risk of sudden tool failure in demanding materials like 4140, 4340, and duplex stainless steels.
⚖️ Optimized for CNC Production: Designed for predictable wear and long tool life under consistent, high-parameter conditions, minimizing unplanned stoppages.
