Product Description

The VALUE COLLECTION CCT1578 is a 39-piece tap and die set covering UNC thread sizes from 4-40 up to 1/2-20. Both the taps and round dies are manufactured from high speed steel (HSS), providing the hardness needed to cut threads in mild steel, aluminum, brass, and other common trade materials. The dies are adjustable and sized at 1 inch outside diameter, making them compatible with the included adjustable die stock. This set is suited for maintenance technicians, pipefitters, electricians, and general trade professionals who need a wide range of hand-tapping capability in a single organized kit.

Thread sizes included span standard UNC fractional and numbered sizes as well as 1/8-27 NPT, making it useful in both fastener repair and pipe fitting work.

Installation Notes

Hand tapping and die work should be performed with the workpiece secured and the correct cutting fluid applied for the material being threaded. Power down and de-energize any equipment before attempting thread repair on installed components. Follow applicable trade codes and manufacturer guidelines when rethreading fasteners or fittings in pressurized or load-bearing assemblies. Inspect taps and dies for wear or chipping before each use to avoid thread damage.
