The Marcrist Diamond Core Drill Bit 127mm is a professional-grade diamond core drill bit engineered for large-diameter rotary drilling in concrete, brick and block. Designed for demanding trade applications, this high-performance core drill bit delivers smooth starts, efficient cutting speed and extended service life. Equipped with precision diamond segments, this rotary core solution ensures accurate entry and consistent drilling performance in dense concrete and masonry materials. The unslotted, dynamically balanced steel barrel reduces vibration, improves control and produces cleaner holes during operation. Designed for rotary action only, this diamond core drill bit connects via a 1/2″ BSP (female) fitting and is compatible with SDS Plus machines (using suitable adaptors) and standard 3-jaw chuck drills. Suitable for wet or dry applications, it can also be paired with dust extraction equipment for cleaner and safer working conditions. Built for professional use, the Marcrist 127mm core drill bit delivers durability, reliability and high-performance results in heavy-duty concrete drilling environments.
