What Kell-Strom tool does

Kell-Strom Tool Co. Inc., founded in 1942 and headquartered at 214 Church Street, Wethersfield, Connecticut, is a privately held specialty manufacturer of precision aerospace service tools and ground support equipment. The company's core capabilities span prototyping, calibration, precision manufacture, technical support, and repair of tooling used in turbine engine assembly, maintenance, and transport. Its product portfolio centers on engine build stands, wash rigs (e.g., the KS5562), custom foam cases for engine protection, and specialty tooling items (e.g., PWC40560) manufactured under license, plus spark plug and engine ignition tooling produced under license from Champion Aerospace.

The business operates an OEM licensing and channel-partner go-to-market: Kell-Strom holds direct licenses from Pratt & Whitney Canada to support the full PWC turbine engine product line (JT15D, PT6, PW100-PW900 series) and three Pratt & Whitney Aeropower APU models (APS2300, APS3200, APS5000), and a co-development partnership with GE Honda Aero Engines for the HF120 turbofan. The company maintains ISO 9001:2015 certification and CAGE Code 75245, and serves as a supplier to major global aerospace OEMs including Lockheed Martin, Northrop Grumman, Airbus, Honeywell Aerospace, Cessna Beechcraft, Pilatus Aircraft, AgustaWestland, and Honda Jet.

Revenue mechanics are enterprise, quote-based, and license-anchored: Kell-Strom manufactures under OEM licenses and ships through direct sales to OEMs and to aerospace MRO providers, with Aviall (a Boeing company) acting as its exclusive global distributor since 1970. The firm does not publicly disclose pricing, revenue, or headcount beyond a stated 11-50 employee range, and operates without disclosed outside capital, M&A activity, or diversification away from precision aerospace tooling.
