A hammer tacker works differently than a squeeze-style staple gun: you swing it like a hammer, and the staple fires on impact. That makes the DeWalt Carbon Fiber HMR Tacker a fast way to run through big jobs like house wrap, roofing felt, insulation, screen material, or carpet padding without stopping to reset your grip after every shot.The carbon fiber body keeps it light for repetitive swinging, while the 7-inch handle gives you reach and leverage on longer runs. It's built around DeWalt's T50 staples with a 3/8-inch crown, accepting fastener lengths from 5/16 inch up to 1/2 inch, so you can match staple depth to the material you're securing. This is a manual, non-electric tool, meaning no cords, batteries, or compressors to manage on the job.
