SDS-max Pro 4 / 35 x 520 mm. Unmatched destructive power with an extremely robust and aggressive solid carbide cutting edge. Consistently long lifespan thanks to a short head with large-volume dust channels for frictionless removal of drilling dust and minimal heat generation. Maximum drilling speed is achieved through diagonally arranged secondary cutting edges for aggressive drilling progress. Optimal centering is ensured by a drilling-active centering tip that provides better guidance when drilling in concrete and reinforced concrete. Precise hole diameters are guaranteed by an innovative wear marking that serves as an indicator for dimensional accuracy. The vibration control features an optimized vibration value, making it ideal for the toughest demands on the construction site. Suitable for use in concrete, masonry, and natural stone.
