Drilling deep, large-diameter holes for heavy-duty structural anchoring or piping rough-ins through dense masonry can easily ruin standard drill bits. Short or unhardened bits bend under high rotational load, lose their cutting edges against hard aggregate stones, or fail to clear thick dust from deep channels, which can overheat your tool. The Ingco DBH1212004 Professional SDS Plus Hammer Drill Bit is an industrial-grade masonry accessory engineered to handle high-impact, deep-reach drilling tasks. Featuring a heavy 20mm cutting diameter and an extra-long 450mm total length footprint, this high-durability core bit drives power directly into tough building substrates with clean tracking and absolute structural control.

The incredible breaking power and extended service life of this rotary hammer accessory come from its premium cemented carbide cutter head insert. This ultra-hard carbide tip retains its sharp geometry under extreme thermal friction and high-impact hammering forces, pulverizing dense stone and reinforced brickwork without fracturing. The solid steel body features a specialized deep-channel dual spiral flute layout that removes high volumes of dust and debris away from the drilling face, preventing binding and lowering running temperatures during deep boring. Outfitted with a standard SDS Plus drive shank, it seats firmly into quick-change rotary hammer chucks with zero slip, ensuring maximum axial energy transfer for professional masonry, foundation, and electrical installations!
