The industry's first cordless lithium-ion copper tubing cutter cuts up to 10X faster than conventional cutters. Engineered with plumbers, mechanical contractors and remodelers in mind, this versatile copper tubing cutter runs at 500 RPM for unmatched cutting speed. The M12TM Lithium-Ion Battery (sold separately) and ultra-efficient gearing allow you to make up to 200 cuts on a single charge. The patent-pending cutting mechanism automatically adjusts diameter to cut Type K, L and M copper pipes from 3/8" to 1" (OD from ?" to 1-1/8"). The unique rotating cutting head cuts installed copper piping with as little as 1-1/2" clearance, and the lightweight, inline design provides a longer reach and reduces wrist strain when you're working in confined spaces. A built-in LED light illuminates the cutting surface. The metal cutting head is corrosion and rust resistant, and sealed for water protection, while electronic overload protection and unibody construction provide additional durability. An onboard, real-time battery fuel gauge helps you monitor the charge precisely, so there's less downtime on the job.
