Duratool D03383 12mm x 460mm SDS-Plus Long Drill Bit

The Duratool D03383 SDS-Plus drill bit provides the reach and precision needed for demanding masonry and concrete work. With a 12mm diameter and a 400mm effective drilling length, this tool is built for deep holes, cable routing, and conduit runs where standard bits fall short. Designed for heavy-duty fixings, it ensures clean and accurate clearance holes for anchors and bolts. Built for longevity, the bit features a fully hardened chrome-alloy steel body with an HRC 48 rating to reduce breakage and extend service life on site. The tungsten carbide tip maintains high cutting efficiency even when working through tough aggregates. To prevent heat build-up and maintain drilling speed, the 4-flute helix design allows for rapid dust removal during operation. Whether you are working on professional construction sites or DIY projects, the shot-peened surface adds extra structural strength to help prevent stress fractures. This bit is compatible with all SDS-Plus rotary hammer drills, making it a versatile addition to your power tool accessories.
