Hole Saws & Core Bits – Product list
Hole saw arbors
An arbor connects a hole saw to your drill's chuck, and getting the right fitting matters as much as the hole saw itself. The Faithfull Holesaw Arbor SDS Plus Fitting 14-30mm and 32-210mm versions cover the full range of hole saw diameters with a direct SDS Plus connection, letting the rotary hammer's chuck drive the saw without a separate keyless adaptor.
Extension adaptors for deeper reach
When a standard hole saw or core bit can't reach through a thicker wall or floor, extension adaptors add length between the drill and the cutting tool. CorePlus offers hex extension adaptors in 88mm and 240mm, alongside SDS extension adaptors in 115mm and 240mm, giving you the reach to match the fitting type on your drill.
Core drill bits and drift pins
The CorePlus DCMD10200 Tapered Masonry Drill Bit gives a dedicated pilot for core drilling into masonry. Once a core is cut, the CorePlus Drift Pin knocks the spent core out of the bit body, a step that's easy to overlook but essential for keeping a core bit cutting cleanly on the next hole.
Hole saws and sets
The LENOX INT700G General Purpose Holesaw Set (7 Piece) gives a spread of common diameters for general cable, pipe and fitting holes in one purchase, while the Starrett A6-4 HSS Drill Hex Pack covers a wide 14-125mm range for varied hole saw needs.
Countersinks and pilot drills
For finishing screw holes cleanly, IRWIN's Pilot Countersink range, including No 8 and No 10, or the 3 Piece Set, drills a pilot hole and countersinks the screw head recess in a single pass, avoiding a separate countersinking step. The IRWIN Drive Plate & Pilot Drill serves as a replacement pilot component for hole saw arbors that have worn or need a diameter change.
Matching accessories to your hole saw system
Arbors, adaptors and pilot drills are typically matched to a specific hole saw diameter range and drill fitting (SDS Plus, SDS Max or hex), so check the stated compatibility on each product page against your existing hole saw and drill before ordering, since these components aren't universally interchangeable across brands.
