Overview
Extremely popular in the oilfields and elsewhere, Kingston’s 7.09” bore HP model and 9.25” (or 10.1”) bore HPX model deliver superior power and cutting performance on large and long workpieces. At the heart of these machines is a strong and rigid headstock and 22” bedway made with high-quality casting for greater stability and accuracy in heavy-duty applications. The powerful 30 HP spindle motor features 16 spindle speeds and the gear box features 40 kinds of feed changes. Kingston’s HP model is bigger, stronger, more precise, and more reliable than 6” bore machines, and the larger HPX model is in a league of its own. Available in 34” and 40” swings and lengths from 80” to 280. Watch the video to see the HPX in action!
