Irwin IRW97606 Fractional Tap Hex Die Set 66 Pc

Product Description

The IRWIN IRW97606 is a 66-piece fractional tap and hex die set designed for threading operations on ferrous and non-ferrous materials. The set covers both cutting new threads and restoring damaged or worn threads on fasteners, fittings, and threaded rod. It is a bench-ready solution for machinists, maintenance technicians, pipefitters, and electricians who need a complete fractional threading kit in a single organized case. The set weighs 18.89 pounds, reflecting a robust assortment of hardened tooling suited for shop and field use.

This set is suited for general fabrication, mechanical maintenance, and trade applications where fractional inch thread sizes are required. Common use cases include creating threaded holes in metal stock, chasing corroded fastener threads on mechanical equipment, and re-threading plumbing or structural hardware. The fractional sizing makes it appropriate for standard inch-based fastener work across HVAC, plumbing, electrical, and general industrial maintenance environments.

Installation Notes

Taps and dies should be installed and operated by qualified tradespeople familiar with threading procedures and workpiece material requirements. Always secure the workpiece firmly before threading and use appropriate cutting fluid to extend tool life and produce clean threads. When chasing existing threads, inspect fasteners and fittings for structural integrity before re-threading. Follow applicable shop safety practices and relevant codes such as NFPA 70 or IFGC when threading components for electrical or gas system applications.
