Used in demolition hammers and stand-up breakers, the 1 1/8-inch Hilti hex connection polygon chisels feature a unique polygon design. This design creates durable chisels that stay sharper and can help customers improve their performance, productivity, cost savings and comfort. The self-sharpening chisels make resharpening and rehardening unnecessary, resulting in high performance levels throughout their life. The chisels increase the working length of flat and wide-flat chisels by 100 percent and the moil point can wear up to four inches in length while maintaining a point suitable for breaking concrete. Over the chisel’s life, a customers’ chiseling efficiency and removal rate increases by up to 30 percent compared with a standard chisel, meaning a tool will be used up to 30-percent less while accomplishing the same work. The chisel’s design helps prevent jamming in base materials, which helps reduce jobsite interruptions and the risk of tool damage.
