The decision turns on two factors: rig type and site conditions. Dry diamond core bits suit hand-held machines and situations where running water to the drill head is not practical, typically lighter masonry or single-trade work. Wet diamond core bits are used where the rig supplies a continuous water feed, which is standard on larger, production-grade rigs drilling reinforced concrete or high-aggregate material at wider diameters. Check your rig's water-feed capability before selecting a bit category.
The key connection point is the thread or bayonet fitting on the bit's barrel, which must correspond to the drive unit's arbor specification. Common thread standards include 1 1/4 inch UNC and M16, but manufacturers vary. Check the drive unit's arbor spec against the bit's listed connection type before ordering. If the product page does not make this clear for your particular machine, use Ask Simon on the relevant product page for an instant fitment check.
At minimum, most rigs require a pilot drill to centre the bit at start-up and prevent walking on the surface. Depending on your setup, you may also need an adaptor to bridge a thread-size difference between bit and drive unit, and a core ejector to clear the slug from inside the barrel after each hole. These items are listed under the Dry Core Accessories child category within this section.

Diamond Cores
Core drilling through concrete, brick, or stone calls for tooling that holds its geometry and cuts cleanly rather than wandering or overheating under load. Diamond Cores is the section within PartsForMachines where trade buyers find the full working assembly: the bits that do the cutting, and the accessories that keep the rig running correctly between jobs.
Three child categories cover the range. Dry Diamond Core Bits carries the tooling used without water cooling, suited to hand-held rigs and lighter masonry applications where a wet supply is impractical. Wet Diamond Core Bits covers the larger-diameter and production-grade cutters that rely on a continuous water feed to flush swarf and manage heat at the cutting face. Dry Core Accessories holds the ancillary items: pilot drills, adaptors, core ejectors, and the connectors that tie a bit to the drive unit. Abracs lines account for the diamond cores in this section.
Selecting the right bit involves matching three variables: the core diameter required by the installation, the material being drilled (concrete hardness, aggregate type, reinforced or unreinforced), and whether the rig supplies water or runs dry. Segment specification varies between manufacturers for exactly these reasons, so checking the bit's published material suitability before ordering avoids a wasted run. If the specification on the product page leaves any doubt about fitment to your particular drive unit, use Ask Simon on the relevant product page for an instant fitment check.
