GREENLEAF CORPORATION introduced a new line of high-performance, solid-carbide end mills – Greenleaf-360 – complementing the XSYTIN®-360 line of solid-ceramic end mills. Greenleaf-360 end mills combine a proprietary flute design with a high-performance carbide substrate that allows for fast and efficient material removal with less stress induced into the part. A combination of strength, toughness, and heat resistance means that machining capabilities from roughing to finishing can be completed with extended tool life and predictability.

Greenleaf-360 high-performance end mills have shown speed and feed performance 25-50% higher than the competition with extended tool life, according to the developer.

The new end mills use a substrate that has proven capability in various materials, from low-carbon steel alloys to heat-resistant alloys. The sub-micron grade provides toughness and wear resistance in a single grade that can be applied in many different applications.

The novel PVD coating that is standard on all Greenleaf-360 end mills provides added productivity and performance. It offers a very low coefficient of friction with an extremely high service temperature range. This combination results in high wear resistance and allows for higher speed capabilities, especially in heat-resistant alloys.

“This high-performance carbide end mill line provides increased tool life and productivity for our customers, which ultimately leads to increased value. As a world leader in material science and tooling innovation, we worked hard to make sure that our carbide end mill introduction was one of true high performance,” stated Greenleaf Corp. EVP-Commercial Bernie McConnell. “The high-performance carbide end mill market opens up a whole new opportunity for Greenleaf to expand our presence and market share in new and existing customers.”

Unique features and benefits of Greenleaf-360 end mills include:
  A proprietary flute design that reduces cutting forces and provides maximum material removal;
  Full line of 4, 5, and 7 flute configurations provides solutions from full slotting to high-speed machining;
  Extended shank length options allow for effective completion of long-reach applications;
  High-performance substrate and coating combination offers versatility in machining various workpiece materials; and,
  Regrind capabilities to like-new condition for added cost savings and value.

Ideally suited for machining materials in the aerospace, automotive, die and mold, medical, and power generation industries, Greenleaf-360 inch and metric end mills are available now.
