Bosch PRO SPEED X SDS Max 4 Cutter Head Masonry Drill Bit

The Bosch PRO SDS max-7 Drill Bit in 52mm x 570mm is the largest diameter in the range, with a 570mm length. It is the one to choose when you need big holes in concrete, limestone and masonry, such as for larger openings and heavy-duty work. The robust carbide 4-cutter head punches into tough materials, while the specially designed flutes help reduce vibration and remove dust effectively. It lasts up to 2x longer than a Bosch SDS max-2 Drill Bit, so you can keep drilling efficiently, time and again.
