Hymnorq 5-in-1 Copper Pipe Swaging Tool Drill Bit, 1/4" to 3/4" HVAC Tube Expander, 1/4" Hex Shank Spin Set for Soft Copper & Aluminum Tubing Repair
5-in-1 Multi-Size Efficiency: Features a stepped design covering 5 common HVAC tubing sizes: 1/4", 3/8", 1/2", 5/8", and 3/4". Eliminates the need to switch between different bits, significantly speeding up swaging work for air conditioning and refrigerator repairs.
Friction Heat Swaging: Designed to work with high-RPM power drills. The tool generates friction heat to soften the copper pipe locally, creating a uniform, crack-free expansion. This ensures a tight fit for brazing without the need for extra coupling fittings.
Secure 1/4" Hex Shank: Equipped with a standard 1/4-inch hex shank that fits securely into pistol drills and impact drivers. The design prevents the bit from slipping in the chuck under high torque, ensuring consistent power transfer.
Cost & Time Saving: By swaging the pipe end to connect two tubes directly, you eliminate the need for copper coupling fittings and reduce brazing points by 50% (one joint instead of two), lowering material costs and leak risks.
Durable Performance: Crafted from blackened high-carbon steel for heat resistance and durability. The laser-etched size markings remain visible after extended use. Note: Intended for soft copper and aluminum tubing only; not for hard copper.
