A Guide to GCT’s 6 Series of High-Performance Milling Cutters
At GCT, we understand that precision machining starts with selecting the right tool for the material. Different metals and alloys have unique properties—hardness, toughness, thermal conductivity, and more—that demand specialized cutting solutions. To empower our customers with optimal performance and efficiency, we’ve developed six distinct series of milling cutters, each engineered for specific materials and applications. Here’s a breakdown of how our product line ensures superior results across a wide range of machining challenges.
1. N550 Series: Perfect for Aluminum and Soft Non-Ferrous Metals
Aluminum and soft non-ferrous metals (e.g., brass, copper) require tools that minimize heat buildup and prevent material adhesion. The N550 Series features sharp cutting edges, polished flutes, and advanced geometries to deliver smooth finishes, high chip evacuation, and extended tool life. Ideal for aerospace, automotive, and electronics industries where precision and surface quality are critical.
2. KP400 Series: Optimized for Low-Alloy Steels (Up to 42 HRC)
Low-alloy steels are widely used in general engineering and construction due to their balance of strength and machinability. The KP400 Series combines toughness and wear resistance to handle materials with hardness up to 42 HRC. Its robust design ensures stability in roughing and semi-finishing operations, making it a go-to choice for machinery components and structural parts.
3. M600 Series: Master Stainless Steel, High-Alloy Steels, Cast Iron, and Carbon Steel
Stainless steel, high-alloy steels (55–60 HRC), cast iron, and carbon steel pose challenges like work hardening and abrasive wear. The M600 Series tackles these with specialized coatings, heat-resistant substrates, and optimized cutting angles. Whether you’re machining valves, pumps, or heavy-duty equipment, this series ensures durability and consistent performance in demanding environments.
4. H680 Series: Conquer High-Hardness Steels (58–65 HRC)
Hardened steels, tool steels, and mold steels (58–65 HRC) demand extreme hardness and thermal stability from cutting tools. The H680 Series employs ultra-fine carbide grades and advanced coatings to resist wear and maintain edge integrity. Perfect for die/mold manufacturing, automotive tooling, and applications requiring tight tolerances on hardened materials.
5. S680 Series: Engineered for Titanium and Nickel-Based Alloys
Titanium alloys and nickel-based superalloys (e.g., Inconel) are notorious for poor thermal conductivity and high chemical reactivity. The S680 Series addresses these challenges with high-pressure coolant channels, variable helix designs, and coatings that reduce heat and built-up edge. Trust this series for aerospace, medical, and energy sector applications where difficult-to-machine materials are standard.
6. KP650 Series: Universal Precision for Finishing Operations
For high-precision finishing of alloy steels, carbon steels, and stainless steels, the KP650 Series stands out. Its versatile design balances sharpness and rigidity, delivering exceptional surface finishes and dimensional accuracy. As a general-purpose tool with excellent adaptability, it’s ideal for industries ranging from automotive to mold-making, where both quality and efficiency matter.
