This Bosch PRO SDS plus-5X is a 17mm diameter, 465mm length masonry drill bit, built for large-diameter, deep drilling tasks in reinforced concrete. Supplied as a single bit. The 17mm bore suits substantial fixings, conduit entries, and service penetrations, while the 465mm length handles thick structural concrete walls with confidence — ideal for heavy trade and infrastructure work.
