Diamond Core Drill Set 11pc Masonry Hex & SDS Plus Arbours

A practical diamond core drill set for cutting larger holes in masonry where a clean, tidy opening is needed. The 11-piece set includes laser welded core drills, both Hex and SDS Plus arbours, plus the main accessories needed to get started on common drilling jobs.

Used for trade work, renovation and general building jobs, this set suits builders, plumbers, electricians and maintenance users who need to drill for pipework, vents, cable runs and similar fittings. It is useful when working on brick, block and other masonry materials where standard drill bits are not suitable for larger openings. Having both arbour types means it can be used as an SDS core drill set or on the Hex arbour, depending on the drill you are using, which helps when moving between site work, workshop tasks and repair jobs.

The included core drill sizes are 38mm, 52mm, 65mm, 117mm and 127mm, covering a good spread of common hole sizes. A 150mm working depth is suitable for many standard applications, while the 25mm solid extension with 1/2in. BSP fitting adds useful setup flexibility where a little extra reach is needed. Angled rear slots and a helix barrel design help move dust out during drilling, which can make repeated use more straightforward and help keep the cut clearer as you work. The set also includes a 13mm taper drill, guide rod and drift key, with everything kept together in a carry case to help keep parts organised between jobs.
