Dewalt DWA1451 Tap Die Set 6-32 to 1/4-20 Unc 17 Pc

Product Description

The DEWALT DWA1451 is a 17-piece tap and die set covering UNC thread sizes from 6-32 up to 1/4-20. It includes both taps and hex dies machined from carbon steel, with a taper chamfer ground into each tap to aid thread starting. The set is sized for field and shop use by electricians, HVAC technicians, plumbers, and general maintenance trades who need to cut or restore threads on fasteners and tapped holes in ferrous and non-ferrous materials. At 0.54 pounds, the packaged kit is compact enough to carry in a service bag without adding significant weight.

This set is well suited to residential and light commercial service work where small-diameter machine threads are common — panel enclosures, electrical boxes, equipment frames, and mechanical assemblies that use 6-32, 8-32, 10-24, 10-32, or 1/4-20 fasteners. The included tap handle and hex die handle mean the kit is self-contained for most thread-cutting tasks without requiring separate tooling. It is practical for both cutting new threads and chasing damaged ones during equipment repair or replacement.

• Tap handle and hex die handle included — complete, self-contained kit

Compatibility

Designed for cutting and chasing UNC machine threads in the 6-32 to 1/4-20 range on standard ferrous and non-ferrous materials commonly encountered in HVAC, electrical, plumbing, and general mechanical service applications.

Installation Notes

Thread cutting should be performed by a qualified tradesperson familiar with proper tap and die technique. Always use an appropriate cutting fluid when tapping ferrous materials to extend tool life and reduce the risk of tap breakage. Back the tap off periodically during cutting to clear chips from the flutes. Inspect threads with a matching fastener before placing the assembly into service.
