Erickson™ Quick Change Flange Shank Tooling System

QC40 Series

With an Erickson QC locknut retrofitted to manual-loading milling machine spindles, the Erickson Quick Change Flange

QC Taper Tooling can be used as a quick-change system. These tools are manufactured from premium materials

and meet or exceed the latest ISO-1947 taper accuracy. The QC40 tools are balanced-by-design and will perform

effectively up to 8,000 RPM. For any applications higher than 8,000 RPM, WIDIA™ recommends that the complete

toolholder assembly (toolholder, collets, hardware, and cutting tools) be balanced as one identity.
