Feature: The product is made of high quality alloy with high hardness and good wear resistance. It is suitable for dressing and grinding the surface of concrete to enhance the adsorptive force of ceramic tile on the wall. With the use of electric hammer, you can greatly improve your work efficiency. When the initial construction of a concrete building is just completed, there will be a large amount of residual concrete on the surface. In the construction of ceramic tiles, it is necessary to remove these uneven concrete. Strong alloy material, long service life. Specification: Material: Alloy Type: 9 teeth; 12 teeth(Optional) Package list: 1 * Hammer head Note: The actual product color may deviate from the photo due to light.
