Greenleaf Corporation is a leading developer of cutting tool technology, specializing in the manufacturing of high performance tungsten carbide and ceramic inserts as well as innovative tool-holding systems. Greenleaf continues to build on 60 years of innovation, which centers on supplying customers with productive solutions to every metalcutting situation.
Greenleaf Corporation is positioned to serve the evolving needs of companies in all major segments of the metalcutting industry including gas turbine, steel, medical, roll turning, automotive, machine tool and rail. Greenleaf's products are engineered to provide optimal performance against a wide range of materials under the most rigorous metalcutting conditions.
In addition to specially engineered tool holding systems and a comprehensive line of carbide inserts, Greenleaf offers high-quality ceramic and ceramic composite materials, which can be custom designed for specific machining applications.
Ideal for heavy-duty cutting in severe interruptions and uneven surfaces. Replaceable components maximize cutter life while providing deep depths of cut.
Also available as end mills, face mills and sinusoidal.
The Greenleaf Powersine® inserts are uniquely designed to have all four edge variations built into one insert, unlike other manufacturers who require sets of inserts. The sinusoidal or wave-type edge fits into the standard PowermillTM cutter body and is especially helpful when deal- ing with long spindle extensions and limited horsepower machinery.
Quiet and free-cutting mills with screw- on insert designs to make the most out of the available horsepower. The free cutting action results in longer tool life and improved surface finishes. Available in end mills and face mills in a wide range of small to large diameters.
High-speed ceramic or standard-speed carbide milling with positive and negative designs for a broad range of materials. 
High-velocity cutters with ceramic inserts for use in high-temp alloys, hard metals, cast irons at high speeds and accelerated feed rates. Precision nests provide multiple insert configurations and body protection. 
Standard screw-on and mechanically held indexable slotting cutters. Special application cutters designed to produce precise narrow width slots.
