Our 48mm High Speed diamond core bit with a 1/2″ Gas fit back end is designed for fast, precise drilling where speed and efficiency are critical. Manufactured in-house by Cutting Edge Diamond Tools in Sydney and Melbourne, this bit is built to exacting standards to ensure consistent performance across demanding applications. The 1/2″ Gas thread allows the bit to spin directly onto the internal thread of compatible core drills, providing a secure fit and smooth operation. Supplied in a standard 450mm length (with custom lengths available), these bits are kept on the shelf for immediate dispatch, backed by our exceptionally fast manufacturing turnaround.
This 48mm high speed core bit utilises the same premium crown design as our other small diameter bits, with the choice of soft bond or hard bond configurations depending on the material being drilled. A soft bond crown is ideal for harder materials, exposing fresh diamond for continuous cutting, while a hard bond crown is better suited to softer or more abrasive materials, extending the life of the bit. Engineered for durability, these bits are designed to last and can be retipped multiple times using our cost-effective retipping service—making them a reliable, long-term solution for professional concrete drilling.
