Achieve professional pipe expansions with this essential Copper Pipe Swaging Tool Set! This versatile set is designed for expanding both hard and soft copper tubing. It reliably produces a clean, deep flare without causing damage or weakening the metal, ensuring a superior joint for soldering. The comprehensive tool kit simplifies the process of expanding HVAC piping systems. When used with your drill, the set helps maintain the integrity of copper and aluminum, preventing leaks and cracks. The Copper Pipe Swaging Tool Set includes 6 essential pieces with the following diameters: 1/4", 3/8", 1/2", 5/8", 3/4", and 7/8" (outer pipe diameter). It is effective for flaring soft and hard copper, as well as aluminum. The design allows for easy swaging of various pipe types. The built-in stopper ensures significant depth for a secure, precise fit. Key Features Drill Compatibility - These tools are engineered to work with standard drills and/or screwdrivers, requiring a minimum of 1,800 RPM and 500 watts for corded models, or 1,800 RPM and 18V for cordless models. Operating with less powerful equipment may impact performance. Friction-Generated Heat - This process preserves the copper's malleability, ensuring a leak-proof connection. Universal Drill Fit - Functions efficiently with most common drills and drivers*; always check the minimum power requirements. Rapid Operation - Complete flaring and swaging in approximately 5 seconds, up to 10 times faster than traditional methods. Crack and Leak Prevention - The high-temperature swaging process creates a perfect seal, preventing the metal from cracking or thinning. RISK-FREE SATISFACTION GUARANTEE!
