You're doing demolition or concrete work and your cold chisel mushrooms on first impact, shatters mid-job, or rounds off so fast you're buying another one before the day's out. A 3/4-inch hex chisel that isn't built for impact work is just a piece of steel that wastes your time and your hammer. The 10-inch cold chisel with 3/4-inch hex shank is built for rotary hammer and demolition hammer use — the hex seats in the chuck and drives with impact energy rather than relying on the operator's arm. 10-inch overall length gives you reach without deflecting. The 3/4-inch hex is a standard size for SDS-Max and similar demolition hammer chucks. Key Specs Length: 10 inches overall Shank: 3/4-inch hex — fits SDS-Max and compatible demolition hammers Use: Concrete demo, masonry work, heavy-duty cold c Stocked at Crofton Lumber and Akron Lumber.
