Flint Machine Tools

HK-30

The Kingston HK series is the definitive hollow spindle lathe engineered for the most demanding oil country and heavy-duty applications. The HK-30 model features a 30-inch swing over the bed and a generous 125-inch spindle bore to accommodate large diameter and long workpieces such as drill pipe and downhole tools. This machine is built for maximum stability with a shorter swing that provides a lower center of gravity during heavy cutting.

It is equipped with a powerful 20 HP 6-pole Mitsubishi inverter-driven main motor providing high torque and 16 spindle speeds ranging from 5 to 300 RPM. The machine is double chuck ready with an ASA A2-20 spindle nose and features hardened and ground bedways for lasting precision.

Standard features include a hydraulic brake system, 4-way rapid traverse, and comprehensive threading capabilities for Whitworth Metric Module and DP threads. Optional accessories like the semi-automatic air threading attachment enhance its capability for specialized oilfield work.
