The swaging spin tool is designed for the most common tubing diameters in HVAC and it's recommended to both soft and hard copper. The high-temperature method preserves the copper's/aluminum's malleability while performing the swage, preventing cracks and leaks. The swaging spin tools allows you to connect tubes with ease and without the use of extra fittings; sleeves and unions, turning potential waste into actual profit. To top that, you can swages with the swage spin tools in just 5 sec! To perform the swage on copper/aluminum tubing, simply attach the corresponding spin tool size to a drill. Because they perform their job using high-temperature and friction, no clamping tools or holders are necessary. No more struggling with the swaging tool. The drill provides the strength, not your hands! Spin is the new evolution for HVAC swaging tools.
