OTC

OTC (Owatonna Tool Company) is a professional automotive specialty tool and equipment brand with roots going back to 1904 in Owatonna, Minnesota. Now part of Bosch Automotive Service Solutions, OTC supplies dealerships, fleet shops, and independent technicians with specialty tools for diagnosis, service, and heavy-duty mechanical work — bearing and gear pullers, transmission jacks, engine stands, brake service tools, and diagnostic equipment.

OTC's tool portfolio emphasizes application-specific engineering: rather than general-purpose sets, OTC products are typically engineered to a specific service task (harmonic balancer removal, hub-bearing extraction, fuel injector work). The brand is a common sight in professional shop environments where specialty tools are purchased once and expected to perform for decades.
