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 higher material removal and prevents the chisel from jamming. Additionally, the viper tooth design of the cutting edge allows for quicker progress. The chisel is intended 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 flat chisel with SDS plus has a 30% longer lifespan and a 15% higher material removal rate than conventional chisels. Total length mm: 250, chisel cutting edge mm: 20.
