Bosch PRO SPEED X SDS Max Masonry Drill Bit

Lasts up to 2x longer than a Bosch SDS max-2 drill bit, this 45mm diameter, 570mm long SDS max drill bit is made for drilling holes in concrete, limestone and masonry. The 45mm diameter is the largest in the range, ideal for big holes, while the 570mm length suits 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 count on its performance for a long time, even in reinforced concrete.
