SDS Plus Hammer Drill Bit DIAGER RockFaster 118, 3–6 Cutting Edges, for Reinforced Concrete

SDS Plus Hammer Drill Bit DIAGER RockFaster 118 stands out at the forefront of concrete drilling solutions. Designed for compatibility with SDS-plus rotary hammer drills, it is purpose-built for penetrating reinforced concrete and other dense masonry materials. The bit features a solid carbide head, ensuring reliable performance and precise hole formation even when encountering embedded steel rebar.

The RockFaster 118 series incorporates a variable cutting edge design, with diameters from 5 mm to 7 mm utilizing 3 cutting edges, and sizes from 8 mm to 20 mm equipped with 6 cutting edges. This tailored approach optimizes drilling efficiency and maintains the ideal bit geometry for each diameter. The robust steel body and thick core enhance torsional resistance, extending tool life during repetitive use on tough substrates.

Its triple-flute, U-shaped spiral design maximizes dust removal, keeping the drilling area clean and supporting consistent progress. The bit’s precise centering tip reduces wandering at the start of drilling, while the ShockSafe certification ensures balanced operation and minimizes hazardous vibration. Manufactured in France, the RockFaster 118 is suited for professional construction and installation tasks requiring accuracy and reliability.
