Overview
Known as “The Workhorse” in machine shops across the country, Kingston’s heavy-duty HR model has been the industry leader in its class for nearly 40 years. At the heart of this machine is a strong and rigid headstock with a hardened and ground main spindle, which features a 4.09” bore and a 3-point bearing support system for superior cutting capability. Operators benefit from the increased control that comes with 16 spindle speeds (8 – 800 RPM) and a wider range of feeds and threading choices. The unique rib structure of the 22” bedway is made with high-quality casting to ensure greater stability and accuracy in heavy-duty applications. The HR is available in 30”, 34”, or 40″ swing and lengths from 80” – 320”.
