With the Bosch SDS-MAX-7 hammer drill bit, you can drill deep penetrations through thick walls and solid building materials with ease. Thanks to the 1200 mm working length, you penetrate deep structural walls without requiring extensions. The solid carbide 4-cutter head prevents jamming when striking rebar, delivering consistent speed in reinforced concrete, masonry, limestone, and natural stone. Its SDS-Max shank transfers high impact energy directly from your rotary hammer to the 40 mm drill tip. Additionally, the built-in wear indicator lets you verify that hole diameters remain within exact tolerances for secure metal anchor placement.
