What Setco does

Setco, legally Setco Sales Corporation, Inc., is a US-headquartered precision machine-tool components manufacturer and service provider founded in 1912 and operating today as a wholly owned subsidiary of Holden Industries, a 100% employee-owned conglomerate. The company designs and manufactures precision spindles (belt drive, direct drive motor, motorized internal motor, parallel gear, worm gear, and robotic spindles), milling heads (rotary, automatic, fixed, manual, and Headtec), and precision slides (dovetail, hardened way, and linear bearing), alongside NADCAP-approved spark erosion grinding and proprietary upgrades such as Airshield bearing seals, RotoShield coolant unions, and TensionSet systems.

The company generates revenue through two complementary streams: new spindle/milling head/slide manufacturing — including custom engineering and OEM contract work — and a large aftermarket repair and rebuild service covering more than 350 machine tool brands, with rapid (QTA) turnaround options. Since 2012 Setco has expanded internationally via the acquisitions of Ultra Precision Spindles in India and NEO Precision in Taiwan, opening additional service centers in China, India, and Mexico, and consolidating acquired brands (MASTER, POPE, WHITNON, NEO, HEADTEC, GTI). The 2023 acquisition of GTI Spindle Technology added a predictive-maintenance and spindle-analysis-tools portfolio (VibePro, BalancePro, ThermoPro, PowerReader, VibePro 24/7 real-time monitoring) under the GTI Predictive platform.

Setco sells primarily through direct enterprise field sales and inside-sales quote-based pricing, supported by 10 service centers and 325,000 sq ft of global production space across North America and Asia. Customers include machine-tool OEMs and CNC machining operations in aerospace, medical device, automotive, construction, mold, plastics, woodworking, stone cutting, and general metalworking, with named enterprise users such as Doosan, Kessler, Makino, Mazak, Mori Seiki, and OKK. The company is ISO 9001:2015 certified, employee-owned, and operates with a stated workforce of approximately 450 employees.
