Note:

*Decrease both spindle speed and feed rate proportionally when the milling parameters exceed the machine’s maximum

spindle speed;

*Recommend oil coolant for Stainless Steels and Heat Resistance Alloys;

*Recommend using a non-contact measuring device to avoid damaging the precision tip point;

*Decrease both spindle speed and feed rate proportionally in case of chattering.

Engineered for Hardened Steels up to 65HRC – Exceptional Wear Resistance and Toughness
Crafted from premium carbide and coated with advanced high-performance layers, this end mill offers superior wear resistance and edge durability in hardened tool steels. Designed for long uninterrupted runs in demanding applications like mold making and high-precision part machining.
4-Flute Design for Higher Metal Removal Rates and Smoother Finishes
Compared to 2-flute tools, the 4-flute geometry provides more cutting edges, improving chip load distribution and reducing tool deflection. This results in higher productivity, better surface quality, and enhanced performance in finishing and medium-depth cuts on hard materials.
High Red Hardness Coating – Reliable in High-Speed and Low-Lubrication Machining
The tool features a heat-resistant coating that maintains cutting edge integrity at elevated temperatures, making it ideal for dry or minimal-lubrication machining. It meets the needs of modern, eco-friendly, and high-efficiency CNC operations.
Application-Specific Cutting Data Included – Maximize Performance and Stability
Each tool comes with optimized cutting parameters for 65HRC steel, including speed, feed rate, and depth of cut. This allows users to quickly set up efficient machining strategies, reduce trial-and-error, and improve overall productivity.
Versatile for Mold Making, Aerospace, and Medical Part Machining
Well-suited for finishing hardened steels and machining tight-tolerance features, this tool is a reliable choice across industries requiring precision and durability—including aerospace components, aluminum molds, and medical device parts.
