HK/HG
Oil Country Lathes
Hydraulic Brake System
Apron Overload Protection Device Incorporates a Clone Clutch
Semi-Automatic Air Threading Attachment with Taper
HK/HG 2-Speed Tailstock
Overview
The HK and HG models are the heavyweight champs of Kingston's manual line. Available in 12.5” and 14.7” spindle bores, respectively, the HK and HG thrive under the most demanding of work conditions. The HK (available in 30” or 34” swing) consistently leads the industry in heavy-duty oil country applications—with the shorter 30” swing being the most popular for its lower center of gravity and maximum stability during heavy cutting—while the larger HG is available in swing sizes up to 40”. These models are equipped with a powerful 20 HP Mitsubishi inverter-driven main motor (6P) and a hydraulic braking system, with a semi-automatic air threading attachment (complete with taper) as a popular option. Kingston's commitment to building powerful, big bore, heavy duty machines is legendary; the HK and HG are Kingston’s maximal efforts – showcasing our largest spindle bore sizes, heaviest loading capacity, and massive amounts of torque. The HK and HG come front-and-rear-chuck ready (A2-20 spindle nose), with lengths from 120” to 280” between centers.
