SPIN Tools P3000 3-Piece Swaging Spin Set for Plumbing, 1/2, 3/4, & 1in. The Swaging SPIN Tools for Plumbing are designed for the most common tubing diameters in Plumbing, and is recommended for L, K, and M pipe types. For tubing sizes 1/4", 3/8", and 1/2" with wall thickness up to 0. 8mm (1. 0mm for 5/8" tubing dia. ). The high-temperature method preserves the copper's malleability while performing the swage, preventing cracks and leaks. Because they perform their job using high-temperature and friction, no clamping tools or holders are necessary. Pre-heating of pipes with 7/8" dia. and up will make the swage process even easier. The Swaging Spin Tools Plumbing Edition allows you to connect Plumbing pipes with ease and without the use of extra fittings; sleeves and unions, turning potential waste into actual profit. To perform the swage on copper tubing, simply attach the corresponding SPIN Tool size to a drill (not included). The SPIN tools are designed to work along with drills or screwdrivers, with minimum of 1, 800 RPM and 500 watts for corded drills, or superior and 1, 800 RPM and 18V, or superior, for cordless drills. Using the SPIN tools along with less powerful equipment may result in high decrease of performance.
