Hitachi 752225 SDS-Plus 24mm x 450mm Drill Bit

The Hitachi 752225 is a 24mm SDS-Plus drill bit built for punching through concrete, masonry, brick, and block. Its four-cutter carbide tip is the standout feature — where standard two-edge bits can wander or produce oval holes, the four symmetrical cutting edges keep the bit centred, reduce vibration transferred to the operator, and leave a cleaner bore. With a 400mm usable working length, it can handle deep anchor installations, conduit pass-throughs, and structural drilling in a single pass without needing an extension.

The SDS-Plus shank ensures tool-free bit changes on any compatible rotary hammer, which covers the vast majority of light- to mid-duty hammer drills from all major manufacturers. At 24mm diameter, this bit sits in a practical sweet spot for mechanical and electrical trades work. It is a straightforward, single-purpose tool — engineered to drill large-diameter holes in hard mineral substrates quickly and reliably.
