Best of Both Worlds: Carbide’s Strength and Ceramic’s Speed
The phase-hardened ceramic substrate on Greenleaf’s XSYTIN-360 end mills provides ultra-high strength and wear resistance at twice the feed rate of carbide end mills when slotting, pocketing, and profiling high-temperature alloys and other difficult-to-machine materials.

Representing Greenleaf Corp.’s (Saegertown, PA) first foray into the solid round tool market, XSYTIN-360 end mills combine the company’s XSYTIN-1 phase-hardened ceramic substrate with a cutting geometry that’s up to 10 times more productive than solid carbide and ceramic products. The material’s strength enables the user to apply chip loads similar to solid carbide end mills with higher speeds common to ceramic machining, significantly increasing productivity when machining materials used by the aerospace, automotive, die and mold, and power generation industries.
Introduced in 2016, XSYTIN-1 machines a wider variety of materials than any other ceramic in the industry. The phase-toughened ceramic’s high wear and thermal shock resistance easily handle high-temperature alloys, 3D-printed sintered alloys, hardened steel, ductile cast iron, and compacted graphite iron (CGI), making the end mills highly predictable and very versatile.
In hardened steels, tool life is equal to carbide end mills when run at speeds up to 11,460 RPM while removing 73 cubic inches of material. Material removal rates (MRR) are 100% over carbide solutions.
A very broad application range means the end mills can be used in numerous machining centers.
Four-flute design optimizes tool life by reducing vibration in slotting, pocketing, and profiling applications. Their length provides the option for regrind capabilities.
Inch and metric end mills are available.
