Connecting the Right Pieces for a Complete Tooling System

Backed by 80 years of cutting tool experience, HARVI™ Solid Carbide End Mills continue to lead in industry technology and innovation

Making Your Job Easier and More Profitable

HARVI technology has increased customer productivity and provided cost savings in every type of application from general machining to aerospace applications, steels to high-temperature alloys, and roughing to finishing operations. HARVI end mills are designed to make your job easier and more profitable by extending tool life and eliminating time consuming finish passes.

With machine tools being able to operate at higher speeds and feeds than ever before, HARVI end mills can thrive in these conditions, but not alone. Taking advantage of increased operating parameters and high-performance milling techniques requires rigid tool holding and near-zero runout to push HARVI end mills to their full potential. Combining HARVI high-performance endmills with HydroForce Hydraulic Chucks completes this high performance system

The benefits of rigid tool holding, decreased runout, and tool dampening will all contribute to extending the life of HARVI end mills. HydroForce can provide these benefits not only for HARVI end mills, but for all round tool holding needs, increasing tool life up to 30 percent depending upon the application and setup.

HydroForce™ Hydraulic Chucks

Our most advanced and universal hydraulic chuck is your first choice for milling, drilling, and reaming applications. HydroForce hydraulic chucks require only two sizes for all tooling applications. Reducer sleeves are applied for all other diameters.

ERICKSON™ Safe-Lock™ Smart Coolant reducer sleeves are specially designed for secure clamping when used with end mills featuring Safe-Lock™ tool shanks. The special drive feature in the Safe-Lock™ reducer sleeve and grooves in the tool shank prevent the end mill from spinning and pulling out of the sleeve during extreme machining conditions.
