Irwin IR26319 Tap and Die Set Standard Metric 17 Taps

Product Description

The IRWIN IR26319 is a 41-piece standard and metric tap and die set designed for cutting and restoring internal and external threads in trade and industrial applications. The set includes 17 plug-style taps and 17 hexagon-shaped dies covering UNC, NPT, and metric thread forms. Tap sizes span common UNC fractional sizes from 6-32 TPI through 1/2-13 TPI, one 1/8-27 TPI NPT pipe tap, and metric sizes from M4 x 0.75 mm pitch through M12 x 1.75 mm pitch. The kit ships with a full complement of drive handles and gauging tools, making it a self-contained threading solution for service technicians and maintenance trades.

This tap and die set is suited for residential and commercial maintenance work, mechanical contracting, HVAC service, plumbing rough-in, and general fabrication or repair tasks where both inch and metric fastener threads are encountered. The inclusion of NPT pipe tap sizing makes it relevant for pipe-fitting and fluid-system repair work. The broad size range covers the majority of fastener thread sizes found in equipment servicing across multiple trades.

Compatibility

Designed for use with standard UNC inch-series fasteners, NPT pipe fittings, and metric fasteners across the M4 through M12 diameter range. Compatible with common trade applications requiring plug-tap thread cutting or die thread chasing in steel, aluminum, and similar workpiece materials.

Installation Notes

Thread cutting and chasing work should be performed by qualified tradespeople following applicable safety practices. Always secure the workpiece before applying torque to the tap wrench or die stock, and use appropriate cutting fluid to extend tool life and improve thread quality. Inspect taps and dies for wear or chipping before each use, as damaged tooling can strip threads or break inside a blind hole. Store taps and dies in the provided case to prevent edge damage and corrosion.
