Sirius Premium Dry Diamond Core Drill Set 11 Piece

The Sirius Premium Dry Diamond Core Drill Set is an 11-piece kit designed for heavy-duty drilling through brick, masonry, and concrete, supplied in a carry case for easy storage and transport.

The set includes five core drill bits in a range of diameters, two SDS adaptors, two hex adaptors, a pilot drill for accurate centre marking, and a drift key for safe bit and chuck removal. This combination of adaptors and accessories makes the set compatible with a wide variety of professional drilling systems, giving contractors greater flexibility on site.

Each core drill bit features highly concentrated diamonds bonded to precision-machined, premium-grade solid steel barrels. This construction is engineered to maintain drilling speed and extend working life even under the immense stress of drilling hard construction materials. The set is recommended for use with a mains-powered electric drill of at least 850W — cordless models are not suitable for these applications.

Suitable materials include medium soft facing brick, concrete blocks, hard sandstone, coarse sandstone, soft slate, breeze block, and lignacite blocks, making this set a practical choice for general construction, groundwork, and building maintenance trades.
