Klein Tools 5191 Conduit Fitting and Reaming Screwdriver

The Klein Tools 5191 Conduit Fitting and Reaming Screwdriver is a professional-grade, dual-purpose tool engineered for electricians who demand efficiency, durability, and precision on every job. Designed specifically for use with EMT conduit, this tool seamlessly combines the functionality of a high-performance screwdriver with a dedicated reaming blade, helping you cleanly and safely prepare conduit ends while tightening fittings — all without switching tools.

Built from heat-treated, high-carbon steel, the reaming blade is precision-machined to smooth and deburr the inside of 1/2″, 3/4″, and 1″ EMT conduit, creating a clean edge that ensures secure connections and prevents wire abrasion. The heavy-duty shaft is securely anchored in a cushion-grip handle, delivering superior torque, comfort, and slip resistance — even in sweaty or gloved hands.

Whether you’re working in tight spaces, overhead installations, or rugged environments, the 5191 stands up to the challenge with a design that emphasizes both functionality and ergonomics. Its non-insulated shaft is ideal for mechanical applications where insulation is not required, making it a trusted choice for prepping conduit in residential, commercial, or industrial settings.
