Bare-Tool Makita BCS550Z 18-Volt LXT Lithium-Ion Cordless 5-3/8-Inch Metal Cutting Saw for $139.99

Review Quickly cut through all-thread, rebar, metal conduit, steel studs, metal roofing, garage door track, unistrut, and other materials more accurately with this powerful little saw. It has a high torque, 3,400 rpm motor to cut faster than a portable band saw. When you’re up on the roof or on a high scaffolding, or there is no outlet nearby, cordless is the only way to go. Working with metal, cords can often snag on sharp corners, creating an electrical hazard.
