The HIT Tool Spring Loaded Cold Chisel is a tool that uses a powerful spring that, when pulled back and released, delivers a striking force of 5,000 PSI to pop rivets and use in metal working. The days of awkwardly juggling a chisel in one hand and a hammer in the other are over thanks to hammerless impact technology. Made with durable steel materials for strength, this chisel comes backed by a limited lifetime warranty.
