Bosch PRO SPEED X SDS Max Masonry Drill Bit

Lasts up to 2x longer than a Bosch SDS max-2 drill bit, this 35mm diameter, 920mm long SDS max drill bit is designed for drilling holes in concrete, limestone and masonry. The 920mm length gives you extra reach over the 570mm option, which suits deeper holes in tough materials. The robust carbide 4-cutter head punches into tough materials, while specially designed flutes help reduce vibration and remove dust effectively. You get dependable performance for a long time, even when drilling reinforced concrete.
