Sirius Premium Dry Diamond Core Drill Set 7 Piece

The Sirius Premium Dry Diamond Core Drill Set is a 7-piece kit designed for heavy duty drilling through brick, masonry, and concrete, supplied complete in a carry case. Each core drill bit is precision machined from premium grade solid steel and features highly concentrated diamonds for fast, effective cutting through demanding construction materials. The set includes three drill bit sizes, adaptors for both SDS and hex fitting systems, a pilot drill for marking the work surface, and a drift key for bit and chuck removal. Suitable for use with a professional standard electric drill of at least 850W — cordless drills are not appropriate for this application. The range of included sizes and adaptors makes this set well suited to contractors, groundworkers, and builders who need to core through walls and blocks across varied site conditions. Recommended materials include medium soft facing brick, concrete blocks, hard sandstone, coarse sandstone, soft slate, breeze block, and lignacite blocks.
