Eagle Cutting Tool TDS-CS-4/40-1/2 Tap Die Set

Product Description

The EAGLE CUTTING TOOL T&DS-CS-4/40-1/2 is a carbon steel tap and die set sized for 4-40 thread forming in 1/2-inch configurations. This set is designed for cutting and chasing both internal and external threads on fastener-scale hardware common in electrical panels, enclosures, and mechanical assemblies. Carbon steel construction provides adequate hardness for threading soft metals, plastics, and light-gauge steel. Electricians, HVAC technicians, and maintenance professionals reach for a set like this when field repairs require re-threading damaged fastener holes or fabricating new threaded connections on small-diameter hardware.

This tap and die set is suited for trade professionals working on residential and light commercial installations where 4-40 machine screw threads are standard. Typical applications include threading work on electrical enclosures, control board mounting hardware, small mechanical brackets, and instrumentation components. The compact 1/2-inch die size makes it practical for tight-clearance work common in HVAC and electrical service environments.

Installation Notes

This tool is typically used by electricians, HVAC technicians, and general maintenance trades. Before threading any component, de-energize and lock out all electrical circuits in the work area per NFPA 70E guidelines. Use appropriate cutting fluid when threading metal to extend tool life and produce clean threads. Inspect taps and dies for wear or chipping before each use to avoid thread damage or tool breakage.
