Bosch PRO SPEED X SDS Max Masonry Drill Bit

Lasts up to 2x longer than a Bosch SDS max-2 drill bit, this 40mm diameter, 570mm long SDS max drill bit is made for drilling holes in concrete, limestone and masonry. The 40mm diameter suits larger holes, while the 570mm length is a practical choice for general drilling where extra reach isn't needed. The robust carbide 4-cutter head punches into tough materials, while specially designed flutes help reduce vibration and remove dust effectively. You can rely on its performance for a long time, even in reinforced concrete.
