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, 920mm long SDS max drill bit is designed for drilling holes in concrete, limestone and masonry. Combining a larger 40mm diameter with a 920mm length, it suits bigger, 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. That means dependable performance over a long working life, including in reinforced concrete.
