Technical Information Screw-On Adapters Screw-On Adapters The universal design of WIDIA™ Screw-On Milling Cutter Adapters enables old and new tool styles to be used interchangeably yet maintain a rigid connection. All adapters offer superior runout accuracy, high metal removal rates, and through-coolant capability. Screw-On Milling Cutter Adapters can be used with WIDIA’s wide range of best-in-class inserts to guarantee excellent cutting results, performance, and productivity. Screw-On products can also be used with a variety of machining applications ranging from low-speed milling applications to rates greater than 20,000 RPM, with the added feature of coolant directed to the cutting edge. The system’s accuracy, repeatability, and stability should be equal or greater to the performance of any similar systems on the market today in all applications.
