Overview

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.

Pros & Cons

👍 Pros

  • Four cutting edges produce cleaner, rounder holes with less vibration than two-cutter designs.
  • 400mm working length handles deep drilling applications in a single pass.
  • SDS-Plus shank fits the widest range of rotary hammer drills on the market.
  • 24mm diameter suits common anchor bolt and pipe-pass-through sizes.
  • Robust carbide tip construction built for repeated use in hard concrete.

👎 Cons

  • 450mm overall length makes it bulky for work in tight or confined spaces.
  • 24mm diameter is a single fixed size with no versatility for other hole dimensions.
  • SDS-Plus shank is not compatible with standard keyless or keyed drill chucks.
  • Heavy-duty concrete work at this diameter demands a rotary hammer with adequate power, limiting use with smaller tools.

Frequently Asked Questions

This bit fits any rotary hammer drill with an SDS-Plus chuck system, which is the most common SDS format for light to mid-duty hammer drills.
The 400mm working length is the maximum drilling depth you can achieve. The extra 50mm accounts for the SDS-Plus shank that sits inside the chuck.
It is designed for concrete and masonry. It can also drill through brick and block, but it is not intended for steel, wood, or tile.
Yes. Four cutting edges remove material more evenly, reduce vibration, and produce a rounder, cleaner hole compared to standard two-cutter SDS-Plus bits.
Use it in hammer-drill (rotary plus percussion) mode. Do not use it in drill-only mode, as the carbide tip is designed to work with impact action.
