Core Drill Adaptors

17 products

Core drill adaptors let you run any core bit on any drill. Most core bits use a 1/2" BSP or 1 1/4" UNC thread and most drills use SDS-plus, a keyed chuck or an M14 spindle; the adaptors here bridge every common combination, and extension bars add reach for deep holes.

Check the thread on your core bit and the fitting on your drill, then pick the matching adaptor. If you are unsure, the product descriptions list the exact fittings each adaptor converts between.

    More about this range

    In this category you will find our selection of high-quality adapters designed to suit all types of core drilling applications. It's not uncommon for drill bits or diamond core drill bits to be incompatible with certain core drilling systems or machines, creating unnecessary limitations.

    Our adapters provide the solution, allowing compatibility across a wide range of equipment. With these, you are no longer restricted to proprietary connections from specific manufacturers.

    We stock several Hilti conversions, plus BSP, UNC, UNF, M14, M16 and SDS+ adaptors. Once fitted, your machine will take any of our diamond core drill bits. Also see core drill spare parts and the full core drilling equipment range.
