The flat chisel with SDS plus jams less and advances faster than conventional flat chisels. The self-sharpening reinforcement ribs create not only lateral but also vertical cracks in the material. This results in a higher material removal rate and prevents the chisel from jamming. Additionally, the viper teeth on the cutting edge allow for quicker progress. The chisel is designed for final adjustment work in concrete and masonry, for tearing down or removing walls, as well as for restoring joints and exposing reinforcements. It is compatible with the SDS plus attachment system. However, it can also be used directly with SDS plus hammers with a rotation stop. The SDS plus flat chisel has a 30% longer lifespan and a 15% higher material removal rate compared to conventional chisels. Total length mm: 250, chisel cutting edge mm: 20.
