Changzhou SDK Precision Technology Co.,Ltd

The High Performance End Mill Series is engineered for manufacturers who demand stable machining, accurate finishing, and long-lasting tool life across a wide range of materials. Each product line is developed with specialized geometries, advanced coatings, and high-grade carbide substrates to maximize efficiency and reduce machining costs. Whether you are cutting steels, hardened steels, stainless steel, or aluminum, this series provides a dedicated solution for achieving consistent high-quality results.

The GM Series Carbide 4 Flute Square End Mill is optimized for alloy steel, carbon steel, and mould steel with hardness up to HRC45. Designed with a 45° helix and a premium Balzers ALCRN coating, it offers excellent wear resistance and smoother cutting at high speeds. The use of GESAC fine-grain carbide (0.6μm grain size) ensures strong toughness and stable performance in finishing operations. Compared with typical HRC55 cutters, the GM Series delivers two to three times longer service life, reducing tool changes and improving productivity.

For harder applications, the HM Series Solid Carbide 4 Flute Square End Mill is designed for hardened steel up to HRC60. This tool features ultra-fine German K44 carbide with 0.4μm grain size and 12% cobalt for superior hardness and toughness. The Balzers DR coating improves thermal stability and prevents premature wear during high-speed machining. Its optimized geometry allows smooth finishing even on demanding hardened steel components. With a lifetime 2–3 times longer than standard HRC65 cutters, it effectively lowers operational costs and improves throughput.

Stainless steel machining requires a tool with strong chip evacuation and vibration control. The SUS Variable Helix U-shape Carbide End Mill is engineered specifically for these challenges. The U-shape flute provides ample chip clearance for heavy feed machining, while the variable helix and pitch help reduce chatter for more stable surface finishes. Balzers AD coating and heat-resistant HELICA coating extend tool life for high-speed cutting. High-toughness carbide and polished flute surfaces reduce friction, enhance chip flow, and increase processing efficiency—ideal for stainless steel parts requiring precision and reliability.

For aluminum machining, the Solid Carbide U-shape DLC Coated End Mill provides excellent chip evacuation, minimal built-up edge, and superior surface finish. The DLC coating significantly reduces friction and heat generation, allowing higher spindle speeds with excellent wear resistance. Its U-shape design supports large-feed machining, while polished flutes keep chips moving smoothly to prevent sticking and improve machining stability. The combination of tough carbide substrate and advanced coatings results in longer tool life and improved machining performance on all types of aluminum alloys.

Together, these four series offer a complete cutting solution designed to help machinists achieve better efficiency, lower costs, and higher-quality results. Whether your work focuses on toolmaking, mould processing, automotive components, or general CNC machining, the High Performance End Mill Series provides the reliability and consistency needed for modern production.
